- Using the appropriate milling cutter with Cu or Al part
To ensure a longer lifetime of cutter and smoothness of parts, the smoothing tool must be distinguished and the allowed using time of it should be reasonable.
- Testing the cutter
It is necessary to test if the swing range of cutter is under tolerance before the machine works. Besides, the cleanliness of tool bit and lock tip influences the degree of accuracy and qualify of parts.
- Making a normal program list
The pattern number, name, program name, machining content, cutter size, smoothing tool, and the safety length of cutter clamping should be included in the program list.
- Reconfirming the date
The 2D or 3D CAD file must be included in the program list before machine works. Rechecking the dates of X, Y and Z axis and marking the tolerance to test.
- Controlling the speed of machine tool
The speed of machine tool must be controlled strictly, S axis and F speed should be adjusted at the same time, the rotational frequency of S axis increases with the F speed.
Finally, the CNC machining part must be in accordance with the type and name of program when it is clamping. Attention the material, size, and the height. Checking the reference angle direction of tooling, which in accordance with the CNC machining program and 3D CAD file.
