1. Reasonable choice of CNC precision machining
The amount of cutting is important to make the most of the potential of the machine, the cutting performance and cutting performance of the tool, and whether the cutting amount (AP, F, V) is reasonable. Achieve high quality, high throughput, low cost and safe operation.
When the car is not running smoothly, the first thing to consider is to choose a large number of rear cutters, then select a larger feed rate, and finally determine the appropriate cutting speed. Increasing the number of rear cutters can reduce the number of knives, and increasing the feed rate can eliminate chips. Therefore, according to the above principle, the cutting amount of the roughing car is conducive to improving production efficiency, reducing tool consumption and reducing machining costs.
When repairing the car, the machining accuracy and surface roughness are high, and the machining allowance is small and uniform. Therefore, when choosing the cutting amount of fine turning, more attention should be paid to how to ensure the machining quality and improve productivity. Therefore, a small (but not too small) rear tool and feed device F should be selected, and a tool material with good cutting performance and reasonable geometric parameters should be selected to increase the cutting speed V as much as possible.

2. Reasonable choice of CNC precision machining tools
1) When using the blank lathe, the tool with high strength and good durability should be selected to meet the requirements of large back cutting and large feed of the blank lathe. CNC programming for 980CNC precision machining
2) When finishing machine tools, high-precision and durable tools should be selected to ensure machining accuracy.
