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.
