How To Make A Reasonable Selection Of Cutting Amount For CNC Lathe Machining?
How To Make A Reasonable Selection Of Cutting Amount For CNC Lathe Machining?
The three elements of cutting conditions: cutting speed, feed and cutting depth directly cause tool damage. With the increase of cutting speed, the tip temperature will rise, and mechanical, chemical and thermal wear will occur. Increasing cutting speed by 20% reduces tool life by 1/2.
The user should choose the cutting speed to be used according to the material being processed, hardness, cutting status, material type, feed amount, cutting depth, etc. As follows: The selection of more suitable processing conditions is selected on the basis of these factors. Regular and stable wear is the ideal condition to reach the end of life. However, in actual operation, the choice of tool life is related to tool wear, changes in processed dimensions, surface quality, cutting noise, processing heat and so on. When determining the processing conditions, research needs to be carried out according to the actual situation. For difficult-to-machine materials such as stainless steel and heat-resistant alloys, coolants or rigid blades can be used.
