To high obedience metal cutting processing, processed material, cutting, cutting condition is about three element. These determine the processing time, tool life and processing quality. Economic useful processing method must be a reasonable choice of the cutting condition.

Cutting condition of three elements: the cutting speed, feed and cutting depth directly caused the damage. Accompanied with the progress of cutting speed, the tip temperature will rise, incubating machine hope for machinery, chemical, thermal wear. Progress rate of 20%, cutting tool life out half.

Feed conditions and tool wear on the back of involvement within the category of small breeds. But feeding, cutting temperature rise, wear and tear on the back. It is smaller than the effect of cutting speed on tool. Cutting depth on cutting tool is not the influence of cutting speed and feed, but in small cutting depth, by cutting the material breeds hardening layer, will also affect the service life of cutting tools.

The user credentials by processing the material, hardness, cutting condition, material selection, feed and cutting depth etc using cutting rate.

Proper selection of processing conditions are selected on the base of these factors. There are rules, solid wear to life's ambition.

However, in the real operation, the choice of the tool life and tool wear, machining size change, appearance quality, cutting noise, heat and so on. When processing conditions were determined, the necessary credentials to reality environment research. Deal with stainless steel and heat resistant alloy hard processing material, can accept coolant or choose good rigid blade.
