CNC machining cutting consumption refers to the amount of material consumed by cutting tools during CNC machining. There are many factors that affect cutting volume, some of the main factors include:

1. Material hardness: The hardness of the CNC vertical lathe workpiece material directly affects the cutting amount. Typically, harder materials cause the tool to wear out more quickly and increase cutting effort.

2. Cutting speed: CNC vertical lathe cutting speed is the speed of relative movement between the cutting tool and the workpiece. Too high or too low cutting speed may lead to increased tool wear and affect the cutting amount.

3. Feed rate: The CNC vertical lathe feed rate is the distance the tool moves along the workpiece surface per unit time. A reasonable feed rate helps control the cutting amount, but an excessive feed rate may cause rapid tool wear.

4. Cutting depth: The cutting depth of CNC vertical lathe is the depth of the tool cutting into the workpiece. A larger depth of cut usually increases the cutting effort because the tool has more cutting area inside the workpiece.

5. Tool materials and coatings: The materials and coatings of CNC vertical turning tools have a significant impact on the cutting amount. Tool materials with high hardness and good wear resistance, as well as tools with good lubrication and anti-wear coatings, can extend tool life and reduce cutting requirements.

6. Use of coolant: Proper use of coolant in CNC vertical lathes can help reduce the working temperature of the tool and slow down the wear rate of the tool, thus affecting the cutting amount.

7. Tool geometry: The geometry of CNC vertical turning tools, such as tool tip angle, edge curvature, etc., has an impact on the cutting amount. Reasonable selection of tool geometry can reduce cutting costs.

8. Process stability: The stability of the CNC vertical lathe cutting process also affects the cutting amount. Good process control can reduce cutting impact and reduce tool wear.

9. Initial condition of the tool: The initial condition of the CNC vertical turning tool, including the sharpness of the cutting edge and the microstructure of the cutting edge, directly affects the cutting amount.

10. Environmental conditions: The temperature, humidity and other conditions of the CNC vertical lathe processing environment may also have a certain impact on the cutting amount.

In CNC machining, reasonable selection of cutting parameters, optimization of cutting tools and workpiece materials, and use of appropriate coolant are all key factors in reducing cutting consumption.
