How to reasonably control the cutting amount of a CNC lathe
For efficient metal cutting, machining data, tools, and cutting conditions are three key elements. These determine processing time, tool life, and processing quality. An economical and effective machining method must be a reasonable choice of cutting conditions.
Factors affecting cutting conditions: cutting speed, feed rate, and cutting depth directly lead to tool damage. As the cutting speed increases, the temperature of the tool tip increases, and mechanical, chemical, and thermal wear occurs. Increasing the cutting speed by 20% can shorten the tool life by half.
The relationship between feed conditions and tool wear occurs in a small range. However, with large feed rate, cutting temperature increases, and back wear is large. Cutting depth has no effect on the tool's cutting speed or feed rate, but at micro cutting depth, the rigid layer generated by cutting parameters can also affect the tool's life.
The user should select the cutting speed based on the CNC lathe processing data, hardness, cutting status, data type, feed rate, cutting depth, etc. Select appropriate processing conditions based on these elements. Regular and stable wear is ideal. However, in practice, the selection of tool life is related to factors such as tool wear, machining size changes, surface quality, cutting noise, and machining heat. Stop the discussion based on confirming the processing conditions and requirements. For refractory materials such as stainless steel and heat resistant alloys, coolant or rigid blades can be used.
