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.

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.

Basic Modeling Rules

Modeling Rules: Bending Example
The sheet metal thickness must be uniform.  
  • Design inner radius (Rinner) of a bend as follows: 0 ≤ Inner radius ≤ ThicknessDesign outer radius (Router) as follows:Inner radius Rinner + Thickness
  • *Automatic quotation is not possible for models with non-uniform thickness. The model modification function can be used to fix these models and may allow automatic quotation.
    For more information, please click here.
 
Feed bending (FR bending)
  • The inner bending radius should be 10 or more. The outer bending radius should be inner radius + thickness.
  • Please refer to the following section for the range of the bending radius.

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.

Hanging Holes for Plating/Painting

When uploading a part in meviy and selecting a plating or painting, please note that a small hole, which should be between Ø 4 to Ø 5.2 mm, needs be added in one corner of your part so that the part can be manufactured with the desired plating or painting. 

If the part exceeds a length of 420mm or the weight of 8 kg, please make sure that at least 2 holes are added to the 3D CAD model to hang the part.

 

Depending on the size and shape of the part, additional holes may need to be added for hanging.

 

If the part cannot be offered automatically, you are welcome to contact us to find a solution.

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.

  • *1 The hole may be deformed if it is below the minimum value.

    The dimensions are therefore inaccurate, but will be processed as they are.

  • *2 If the distance is under the minimum value, re-tapping will be necessary and the fit may be affected.
Example

If there are internal angles of less than 90°, machining may not be possible even within the safe value range. If this is the case, meviy Support will contact you.

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 Rules Example
  • 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

Confirmation of nut interference during bending

  • In the interference analysis during bending, the analysis is performed with the 3D shape of the nut reproduced for the part where the nut can be mounted.
  • If interference with the die is found as a result of the analysis, the area will be judged that the nut cannot be attached.

Sheet Metal Quoting Error Troubleshooting

  • When uploading a model to meviy, a “Quotation failure” error may occur.
  • Below is an overview of why these errors occur and how to resolve them,as well as some example errors.

What is a quotation failure?

When uploading a model to meviy, an error may occur where the model cannot be auto-quoted.

How to check for errors in the project list

  • After uploading a model to meviy, the “” or “” icon will appear if the model cannot be auto-quoted.
  • In this case, please go to the 3D Viewer and confirm the details of the error from the Precaution column.

How to check error messages in the 3D Viewer

  • Please open 3D viewer and check “Precaution”.
  • If you click “Check”, you will see error messages and a range for auto-quotation.
  • Depending on error cause, a range for auto-auotation may not be displayed.

How to locate an error

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.

Quality Control of Nut Mounted Products

Regarding the appearance of nut mounted products

Product with press-fit nut

  • EN 1.0330 equiv. (Electrolytic Zinc Plating) and EN 1.0330 equiv. (Galvanized) may have some plating peeling due to nut mounting.
  • Installation of nuts near the edge of the plate may cause the edge to swell.

Product with weld (spot) nut

  • For products with spot-welded nuts on steel materials,remove burns by using a file or similar tool. Scratch marks may appear due to the filing.
  • EN 1.0330 equiv. (Electrolytic Zinc Plating) and EN 1.0330 equiv. (Galvanized) may have some plating peeling due to nut mounting.
    Spot-welded nuts on stainless steel will be removed the burn marks by electrolytic polishing.

    Also, polishing to remove burns is not performed because it causes plating to peel off.

  • The projection part of the weld nut may be eluted, but the following items are inspected to confirm that there is no problem with fastening.

    Finish marks may remain.

  • – Bolts can pass through
  • – The projection part is not convex more than the material thickness

Regarding the Strength Warranty for Nut mounted Products

Product with press-fit nut

  • We do not guarantee the strength of products with press-fit nuts, but we will ship them after confirming that there are no problems with fastening.

Product with weld (spot) nut

  • We do not guarantee the strength of products with weld (spot) nuts, but we will ship them after confirming that there are no problems with fastening.In addition, periodic evaluations are conducted in accordance with JIS B1196.

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

  • 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
