Precautions for post mold processing
1. The sequence of the tool path of the back mold: how thick is the grooving tool path on the surface of the broad knife? Is the pocket knife limited to the surface grooving rough? Clear corner? Big knife (ball knife) public number: UG programming base camp parallel milling cutter road smooth? Small knife (ball knife) parallel milling tool path limit range clear angle, smooth knife? Flat knife contour profile knife path clearing angle
2. The material used for the rear mold is the same as that of the front mold, and the round nose knife (knife handle) is used as far as possible.
Precautions for CNC machining A. Mould and product matching tolerance 1. The matching positioning of the upper and lower shells is guaranteed by the spigot, and the tolerance of the concave spigot and the convex spigot is generally 0.1 on one side.
2. Usually the accessories (such as transparent mirrors) on the big body of the shell are 0.1-0.2 smaller than the size of the big body on one side.
3. The shape of the movable accessories (such as buttons) on the big body is 0.1-0.5 smaller than the shape of the big body.
4. If the surface shape of the accessories is the same as that of the big body, it can be trimmed from the corresponding position on the body surface.
