Basic Modeling Rules

Modeling Rules Example
The plate thickness must be uniform. Example
Model the inner radius (R) of a bend to be 0 or more and the plate thickness or less. Model the outer radius (R) to be [inner radius R] + [plate thickness]. Example
  • *Bending inner radius should be 10 or more, and bending outer radius should be inner radius + plate thickness.
  • *For the range of bending radius, please refer to the “Range of Bending Radius“.
Example

Hole Identification Specifications

  • After CAD data is uploaded to meviy, it is internally converted into a neutral file format. During this conversion, the hole type information (tapped hole, countersunk hole, etc.) is lost.
  • As a default hole recognition setting, hole diameter and shape features are detected and compared to the hole information database to infer the hole information that will be carried over to the meviy platform.

However, Solidworks users can use a new function that allows you to change user settings to directly transfer original hole information from CAD data to meviy.
Please click here for more information.

Modeling Rules for Keyhole Type Holes

When a keyhole shaped element is detected, it will be identified as a keyhole type hole.

Modeling RulesExample

Model the keyhole type hole to meet all of the following conditional expressions:

d1 ≥ 4.5, d2 ≥ [2 × d1 + 2], h > 0

Example

Suspension Holes for Plating/Painting

If you select plating or painting for the surface treatment, suspension holes for the surface treatment will be required.
If the model does not have holes already, be sure to add through holes near the corners or end face of the part.
*Model the holes so that they are around ø4 to ø5.2 mm.
*For models with a length of 420 mm or greater, or for models with a weight that exceeds 8 kg, add at least 2 holes to the model.

 

Depending on the size and shape of the part, you may need to add more holes or change the suspension holes.
You will be contacted if this is the case.

Tapped Hole Identification and Selectable Sizes

Tapped Hole Identification

  • Hole diameter information in meviy’s hole information database is registered corresponding to the nominal diameters of tapped holes from each uploadable file extension. Detected hole diameters are checked against the table below (Table 1).
  • *If the detected diameter does not match any entry in the table, the hole will be treated as a through hole. However, you can change the hole type or nominal diameter when configuring the quote settings.
  • *If a diameter corresponds to multiple nominal diameters (below, 5.00 mm), the larger nominal diameter (M6) will be prioritized and selected.

Modeling Rules for Perforated Metal

Modeling RulesExample

When requesting a quote for perforated metal parts, model the part using either no holes or only through holes (mounting holes).

(There is no need to model the staggered/lattice-like hole patterns characteristic of perforated metals.)

Hole Identification Specifications

Friction Drilled/Tapped Holes Modeling and Sizes

Friction Drilled/Tapped Holes Modeling Rules

When a cylindrical flange shape element is detected, it will be identified as a friction drilled/tapped hole.

Modeling Rules Example
The inner diameter (d) should follow the same rules as for Tapped Hole Identification described above. Model the flange height (h) and thickness (t) to be less than or equal to the plate thickness. Example

Friction Drilled/Tapped Hole Size Selection

Countersink Modeling and Selectable Sizes

Modeling Rules for Countersunk Holes

When a conical shape element is detected, it will be identified as a countersink.
Modeling Rules Example
Model the angle of the conical shape to be 90°. The ratio between the outer hole diameter (D) and inner hole diameter (d) must be as follows: If d ≤ 4.0 mm, the ratio must be above 1.4, If d > 4.0 mm, the ratio must be above 1.7. Example

Countersunk Hole Identification

The countersunk hole is recognized through two steps below.

STEP1

  • The pilot hole diameters for countersunk holes for each CAD package are registered in the meviy hole information database. Detected hole diameters will be checked against this during modeling (see table below).

  • *2 Pilot hole diameter for Siemens PLM-NX ISO model

STEP2

Once the countersunk hole is recognized according to the aforementioned modeling rules, the nominal diameter is determined according to the pilot hole diameter range. (Table below)

If the detected hole diameter does not match any of the entries on the list of pilot hole diameters, the hole is treated as a through hole (or tapped hole).

However, you can change the hole type or hole diameter when configuring the quote settings.

Bending Conditions

Bending Interference

  • For sheet metal parts, the meviy platform performs interference analysis for the bending process.
  • The forming will be deemed impossible if the results of the analysis suggest there will be interference with the die.

Example 1) Model image before and after bending during normal conditions

曲げ加工の干渉

Example 2) Model image where die interference occurs

Bending interference
  • If a warning message is displayed, check the part for any interference using “Check the interference image” and consider changing the shape. 
  • After taking corrective action, re-upload the 3D model and check the revised quotation results. 
  • The design guidelines for C-bends and stepped bends (Z-bends) are provided below as more detailed examples. See below.

Design Guidelines for C-Bends and Stepped Bends (Z-Bends)

To prevent die interference, design models with reference to the standard shapes shown below.

Modeling RulesExample
  • When outer dimension A is less than or equal to outer dimension C, set inner dimension B so that it is greater than A.
  • Outer dimensions A and C must be at least the minimum bending height (See machining limits: minimum bending height, mentioned above)
C-bend
  • The stepped bend height should be equal to dimension A plus double the plate thickness (t).
  • Dimension A must be equal to or greater than the minimum bending height (See machining limits: minimum bending height, mentioned above).
C-bend

However, the meviy platform determines whether it is possible to manufacture the model based upon positive results of the interference analysis. (Examples given below)

Example 3) C-shaped bending interference: Adjust the size of the channel web in order to clear any interference (the figure on the right shows the analysis image).

 Example 4) Stepped bending interference: Adjust the bending height to clear any interference (the figure on the right shows the analysis image).

Presence of Edges Parallel to the Bend Line

Any backgauges used in the bending process, along with the edges of parts, are taken into consideration in the interference analysis of the bending process. The angle of the part during the bending process may not be stable if there are no edges parallel to the bend line, creating a risk that the bend may not be made in the correct position. If the below message is displayed, consider changing the shape such that the model includes edges parallel to the bend line.

Example 1) No edges parallel to the bend line

 Example 2) Edge parallel to the bend line [automatic quoting available]

Minimum distance between cutout and bend

  • The bending process is carried out by placing the workpiece (to be bent) on a die and punching it from above.
  • However, if the shape of the workpiece does not align on both ends of the die, it cannot be bent.
  • For the minimum distance between the cutout and the bend, we recommend the following.
  • Please note that if the value falls below the minimum value, the bending line may shift because part of the workpiece is no longer covered by the bending die.
  • The dimensions will be inaccurate, but will be processed as they are.
  • In the case of a part that falls below the limit value, it may not be possible to process it. In this case, we will contact you.
  •  
Modelling rules Location
  • For plate thickness t, the limit value of h should be as follows
  • 0.8 ≦ t ≦ 2.0, limit value = 5t
  • 2.3 ≦ t ≦ 9.0, the limit value = 4t
  • For plate thickness t, the minimum and limit values of b should be as follows
  • 0.8 ≦ t ≦2.0, guaranteed value = 2t, limit value = t
  • 2.3 ≦ t ≦ 9.0, guaranteed value = none, limit value = 2t

Range of Machining Limits

The limits for machining and the size ranges are defined for each standard part. Make sure that any models you create fall within the standard range.

About Hairline Direction

  • EN 1.4301 equiv.(single-sided hairline finish) has a hairline finish on the main appearance surface. (See the figure on the right)
  •  
  • The polishing direction of the hairline finish is called the “hairline direction,” and in the meviy sheet metal service, the longitudinal direction of the unfolded drawing created by expanding the 3D model shape is used as the hairline direction.
  •  
  • If you would like to use a different direction, please contact meviy support for a quote.

Logic to determine the longitudinal direction of the development
Calculates the maximum rectangle of the unfolded drawing, and develops horizontally in the direction of the longest side of the rectangle.
Logic to determine the longitudinal direction of the development
Shape with arbitrary hairline direction
In some cases, the maximum rectangle of the unfolded drawing is not defined, or the longest side of the rectangle cannot be defined (See the figure on the right.). For such shapes, the hairline direction is optional, and you can specify the desired direction in the quotation in meviy support.
Shape with arbitrary hairline direction
Effects on unfolded dimension calculation
  • The effect of expansion due to bending must be taken into account when calculating the unfolded dimensions for manufacturing.
  •  
  • In the case of EN 1.4301 equiv.(single-sided hairline), the expansion is about twice the thickness of the plate at each bending point, so the unfolded dimensions become shorter by that amount. As a result, please note that the longitudinal direction in the 3D model and the unfolded drawing may be switched. (See the figure on the right)
Effects on unfolded dimension calculation

About Painted Sheet Metal

  • Hanging jig marks may be left when painting (see diagram on right).
  • The iron phosphate coating is used for surface preparation, and the paint is applied with a thickness of 80µ ± 30 (excluding thickness tolerance).
  • However, this is not a guaranteed value as the coating thickness of the film may vary depending on the shape.
  • We carry out checks with coating thickness gauges, pull-offs with tape and cross-cut adhesion test. We also visually check the appearance of the product by referring to the “Dirt comparison chart” to check for color, dirt, and dimples.
  • To clean, wipe with water and a soft cloth or sponge, or wipe with a diluted neutral detergent, then wipe with a dry cloth. Please refrain from using alcohol and petroleum solvents such as thinner, and benzene.

Dimensional Changes for Clear Resin

Unlike metal, resin is a material that easily deforms as a result of temperature and humidity and changes in dimensions. Accuracy is assured in the following way:
  • Testing is conducted in a temperature- and humidity-controlled environment
  • Accuracy assurance is based on the results of inspections performed immediately before shipment.

Quotable Shapes

Machining Direction

The machining direction can be perpendicular and parallel to the 6 rectangular faces.
Machining at an angle against the direction of the rectangular faces requires dedicated equipment and is not possible with meviy.

*With 3-axis milling, it is not possible to machine at angles that run diagonal to the 6 faces.

Machining Direction

Machining Positions

The green areas below indicate points that can be machined. The yellow areas indicate points that cannot be machined and are therefore not possible with meviy.

Yellow areas can be adjusted or deleted to make an eligible shape.

(1) Pocket Shapes

The shape of a pocket (area cut by the end mill) varies depending on the placement of chamfers and curves (convex and concave). Here are some examples:

The green areas indicate points that can be machined. The yellow areas indicate points that cannot be machined and therefore cannot handled by meviy.
Yellow areas can be adjusted or deleted to make an eligible shape.

(2) Closed Pockets

With pockets that are enclosed by 4 faces, concave curves are required on all 4 corners (whether it is a through pocket or blind pocket), as shown in the left image below.
(Because pockets are machined with an end mill, sharp corners are not possible.)

When adding chamfers as in the images below, up to C15 is possible.
(Chamfers above C15 are machined with end mills, so a conical shape like that below is not possible.)

(3) Open Pockets ①

For pockets not surrounded by 4 faces, some shapes can be created without concave curves.

However, curves are required if the pocket is a blind hole. (This is because a curve will always be formed in the machining direction.)

When adding chamfers as in the images below, up to C15 is possible.
For shapes like the image on the right below, an end mill can be used for chamfering, so chamfers above C15 are possible.

Shapes like those below are machined with a chamfer cutter, so a curve like the left or middle images above will be made at the chamfered intersection.

(5) Holes ①

Unlike pockets, multi-directional machining can be used for holes.
It is possible to add multiple smaller holes or a slotted hole in the lower step of a counterbore hole.

(6) Holes ②
Multi-step holes with more than two steps are not possible. As in the left image below, the hole in the middle step must be the narrowest (in order to work with our system). The shapes shown in the middle and right images below (multiple stepped holes or the largest diameter in the middle step) are not possible with meviy.
(7) Slotted Holes ①

As with round holes, multi-directional machining can be used for slotted holes, and counterboring can be used to create multi-stepped holes.

(8) Slotted Holes ②

More than 2 steps are possible.
The middle step cannot be the longest hole, as in the right image below. However, unlike round holes, slotted holes can feature multiple steps that narrow from the top down, as in the middle image below.

(9) Holes + Chamfers or Curves ①

Chamfers around the mouth of a round or slotted hole are possible up to C15.
It is not possible to add convex curves to the rim of round or slotted holes.

(10) Holes + Chamfers or Curves ②

If the corner of a round or slotted hole is curved, the radius of curvature cannot exceed 0.5.

If a corner is C-chamfered or has a radius of curvature below 0.5, the end product may differ from the model. (If adding a curve and chamfer to a counterbore like the left image below, the hole is machined with an end mill, producing a corner that is sharp or within a 0.5 radius of curvature. For a precision or tapped hole with a pilot hole, like the right image below, the hole is machined by a drill, producing an angled surface.)

It is not possible to add a chamfer or curve to an already curved surface.

Shape Disparity between 3D Model and Finish

In general, the product will be true to the 3D CAD data. However, in the following cases, there may be differences between the 3D CAD data and the actual product.

Internal/External Sharp Corners

tgt04_fac_136_EN
  • If an external corner is sharp or is less than C0.5, the finish will be as follows:

    · External corner C0.1 to 0.5 or less

    For internal sharp corners, the finish will be as follows:

    · Internal corner R0.1 to R0.5 or less

The bottom shape of the blind hole

  • Even if the bottom of the model is flat, the finished product may be a cone shape due to processing characteristics, and vice versa. This may cause the hole to penetrate, interfere with other shape elements, deform, or bulge.
  • If not acceptable, please fill the comment field of hole information instructions with “hole diameter(Φ), depth, flat bottom” and request a manual quotation from meviy support. We will shortly provide you a formal quotation.

Pilot Hole for Tapped/Precision Hole

The pilot-hole depth may not be machined exactly as shown in the model, and if the effective depth (h) exceeds the reference value [model depth minus pilot-hole remaining depth] the pilot hole may penetrate through and interfere with other shape elements.

The pilot-hole diameter may also not be machined exactly as shown in the model.

Pilot hole for tapped/precision hole
Pilot-hole depth reference value = pitch × 2.5 + 2 mm
Pilot hole for tapped/precision hole
Pilot-hole remaining depth reference value = 2.7 mm

Points of Note when 3D Modeling

The manufacturing process takes the 3D CAD data to be exact.

Do not forget to model the following shape elements.

Radius (R) Required for End-Mill Trajectory End Point/Turnaround Point.

The end-mill trajectory will always have an R at the end point and the turnaround point.

Please model an R of at least 1.25 based on end-mill diameter and blade length.

The R required for an automatic estimate depends on the depth of the pocket machining.

The larger the R, the larger the diameter of the end mill that can be used. This means a shorter machining time and a lower cost.

 

No Modeling Required for End-Mill Nose R

Do not model nose R.(The nose R is the minuscule R at the corner of the end-mill tip.)

If a nose R is present, the machining direction cannot be accurately determined, and an automatic estimate is not possible.

Chamfers Over C0.5 Must be Modeled

Chamfers greater than C0.5 must be modeled.

For external sharp corners or corners of C0.5 and smaller, this finish will be C0.1 to 0.5 or less.

Hanging Holes for Surface Treatment Must Be Modeled

  • For black oxide coating, electroless nickel, trivalent chromate, and all anodized aluminum, the part requires holes from which it can be hung and immersed in the treatment material.
  • Model the hanging holes with a combination of two or more of the following shapes. You can use any of the shapes multiple times in the same combination.
  • • Through holes of ø3.5 or greater (precision holes cannot be used)
  • • Slotted holes with a width of 3.5 or greater (precision slotted holes cannot be used)
  • • Closed pockets with width 3.5 or greater
  • • Tapped through-holes of M5 or greater

Recognizing Different Types of Hole

Shape Elements Identified as Holes

In the machining service, the following shape elements are identified as holes. Elements identified as holes can be switched to straight holes or precision holes. If the hole diameter meets certain criteria, you can also switch to tapped holes, insert holes or countersunk holes. For one-step holes and two-step holes, the hole type can be changed at each step. See here for positions where a chamfer can be created in one-step and two-step holes. You can also specify the dimensional tolerance from the hole center.

Recognizing Straight Holes

Any shape that is identified as a hole, but is not initially recognized to be a tapped hole or a countersunk hole, is identified as a straight hole.

Settings for Precision Holes

Any shape identified as a hole can be changed to a precision hole by changing the hole diameter tolerance type of the straight hole. See here for more information about how to switch to precision holes.

Recognizing Tapped Holes

meviy sets the pilot-hole diameter based on the user-set “Tapped Hole Identification Settings” and the file extension (see table below). If the model’s hole diameter matches the settings, it is identified as a tapped hole.
If holes have not been automatically assigned as tapped holes at initial upload, you can also change the hole type manually as long as the hole diameter is within the threshold.
You can also change from tapped holes to straight or insert holes.
See here for the Tapped Hole Identification Settings.

  • Select “User Settings” in the user menu in the top-right of the screen.
  • You can change the settings from the “Tapped Hole Identification Settings” menu.

*If the native file is different from the CAD software settings, the CAD software setting logic will be used for recognizing tapped holes.
Please note

It is recommended that you use the hole commands to model holes. The machining service is designed for modeling generated with the various CAD hole commands, and using the hole commands improves the accuracy of the automatic assignment of tapped holes.

 

(Automatic tapped-hole assignment can also be used when modeling with cutting. However, if there is any discrepancy in the logic, tapped holes cannot be automatically assigned, and holes may end up as straight holes or other types of hole.)

 Please note (SolidWorks users only)

The machining service refers to the CAD names in the SolidWorks Tapped Hole Identification Settings as “SolidWorks(A)” and “SolidWorks(B).” The differences between the two are as shown below.

Select according to your modeling specifications.

If a user of modeling specification “SolidWorks(B)” has set the CAD name to “Use file type” in the Tapped Hole Identification Settings, the “SolidWorks(A)” logic will take precedence.

“SolidWorks(B)” users must set the CAD name to “SolidWorks(B).”

The tapped hole identification logic for the machining service is shown below.

*The machining service’s tapped hole identification logic is designed to round to three decimal places.

*The CAD in the following tables assumes the default versions of the following are used.

It may not work, depending on version upgrades and personal settings.

Settings for Insert Holes

When the quoted material is made of aluminum or resin, the machining service can select insert holes within the threshold using logic equivalent to the tapped-hole identification logic.

The insert material is EN 1.4301 equiv.

There are four nominal lengths for each diameter: 0.5D, 1D, 1.5D and 2D.

However, the number of selectable diameters is M2 to M12, unlike for tapped holes.

Recognizing Countersunk Holes

Conical shapes that meet the following conditions will be identified as countersunk holes.

 

Model the conical shape with an angle of 90°.

Set so that the hole diameter ratio D/d is:
greater than 1.4 (D>1.4d) when d is 4.0 [mm] or less.
greater than 1.7 (D>1.7d) when d is greater than 4.0 [mm].

Recognizing Other Types of Hole

The shapes shown below are recognized as other types of hole. The service is not available if these other types of hole are present.

Decreasing two-step hole
Non-90° entrance chamfer
Tapered hole
Oblique hole
Fillet at entrance
Machined thread

Thin-Wall Judgment Logic

As shown below, if there is a thin wall below the machining limit, out of tolerance will occur due to tearing or shape deformation during manufacturing. *If there is an overlap between the limit values, the larger value will be given priority.

If the thin wall is below the limit, the “Quality Agreement” will be displayed on the screen. Please check the relevant area on the 3D viewer and answer whether you agree with tears, deformations and out of tolerance.

If you disagree, we will not be able to provide an automatic quotation. If you disagree but still want the same quality as the model, please write “disagree with the quality agreement” or something similar in the comment box and request a manual quote from meviy support. After that, you will receive an official quotation response shortly.

Default General Tolerance Standards

The cutting service does not display dimensions or tolerances when 3D CAD data is uploaded other than external dimensions and hole information, assuming that the customer specifies tolerances of their choice.

This section describes the finish of parts where dimensions and tolerances are not displayed.

Default General Tolerance Standards for Machined Dimensions (From Excerpts of JIS B 0405:1991/JIS B 0419:1991)

The following standards are applied to the origin according to machining standards.

The origin can be moved to any position.

Resin Precision Assurance

Unlike metal, resin is a material that easily changes shape or dimensions due to factors such as temperature and humidity. Due to this, precision assurance is performed under the following conditions:
· Inspections are performed in temperature-controlled environments.
· Precision assurance is based on the results of inspections performed immediately before shipment.

Surface Roughness

The surface roughness reference value is √Ra6.3 (√Rz25).

The surface roughness is displayed in the lower left corner of the 3D viewer and the roughness symbol can be changed in user settings.
