What effect does the cutting parameters of PCD tools have on cutting performance?

PCD tools, as superhard tools, use polycrystalline diamond as cutting material. Polycrystalline diamond synthesized using high-pressure technology solves the problems of scarcity and high price of natural diamond, a harder substance in nature. So do you know what effect does the cutting parameters of PCD tools have on cutting performance? The following editor of Zhongyeda will introduce this issue to you.

The effect of PCD tool cutting parameters on cutting performance is as follows:

Cutting speed

PCD tools can be cut at extremely high spindle speeds, but the effect of changes in cutting speed on machining quality cannot be ignored. Although high-speed cutting can improve machining efficiency, the increase in cutting temperature and cutting force under high-speed cutting conditions can cause damage to the tool tip and cause vibration of the machine tool. The reasonable cutting speed of PCD tools is also different when machining different workpiece materials.

Feed amount

If the feed amount of the PCD tool is too large, the residual geometric area on the workpiece will increase, resulting in increased surface roughness; if the feed amount is too small, the cutting temperature will rise and the cutting life will be reduced.

Cutting Depth

Increasing the cutting depth of PCD tools will increase cutting force and cutting heat, thereby increasing tool wear and affecting tool life. In addition, the increase in cutting depth is likely to cause PCD tool chipping.

In summary, this is the effect of PCD tool cutting parameters on cutting performance. When PCD tools of different particle sizes are used to process different workpiece materials under different processing conditions, the cutting performance they exhibit is also different. Therefore, the actual cutting parameters of PCD tools should be determined according to specific processing conditions.
