The main considerations for PCD insert selection are surface accuracy, shape accuracy, dimensional accuracy, tool deformation, reduced duty cycle, reduced downtime, 

increased tool life, hard materials, tool costs, reduced investment, and others.

Cutting parameters of PCD Inserts:

(1) Cutting speed Vc

PCD tools can be machined at extremely high spindle speeds, such as speeds of up to 1000 m/min for turning silicon-aluminum alloys and 3000 m/min for high-speed milling;

(2) Feed Fr

The PCD tool should select the appropriate feed according to different processing conditions. If the feed rate is too large, the surface roughness will be affected, and the cutting temperature will increase.

(3) Cutting depth ap

The PCD tool should select the appropriate cutting depth according to the processing technology, and the cutting depth will affect the tool life.
