What are the common CNC milling machine processing methods?

With the continuous development and innovation of high technology, the application of computer gong processing is more and more widely, so what are the common computer gong processing methods?

1. Flat face parts

Generally used point, linear control computer gongs machine (such as computer gongs drilling machine) to process, the choice of process route, the main consideration of processing precision and efficiency of two principles.

2, plane contour parts

Planar contour parts should pay attention to when using computer processing:

A, cutting and cutting direction control: radial cutting, the workpiece surface has pits; Transverse cut, cut out, the workpiece surface is smooth.

B, an approximation method choice: only with linear and circular interpolation function of computer gongs machine tools in the irregular curve contour machining, requires the use of tiny straight line or arc segment to be machining contour, its error is called a approximation error), approximation, should make the workpiece less error in the acceptable range at the same time, the number of the procedures section is preferred.

3. Stereo contour parts

The following contents should be considered in the processing of three-dimensional contour parts:

A, consider the workpiece strength and surface quality: after the workpiece is forced, the strength is poor, the surface quality is the best.

B, considering the interpolation function of the machine tool: when processing the plane girder straight grain twisted surface, if the machine tool three axis linkage, it has to use the ball milling cutter with lower efficiency; If the machine tool is four axis linkage, you can choose high efficiency cylindrical milling cutter milling.

4. Rotating parts

Rotating parts of the processing commonly used computer gongs lathe or grinder processing, in this process should pay attention to what?

A. Consider the processing efficiency: when machining on the lathe, the machining allowance is usually large, so the rough machining route must be reasonably arranged to improve the processing efficiency. In actual programming, it is generally not appropriate to use cyclic instructions (otherwise, the speed of the empty knife too much). The better method is to use the rough car as soon as possible to remove the material, and then fine car.

B, consider the strength of the tool tip: the computer gong lathe is often used to process small grooves with low strength tools.
