Reasonable choice of cutting amount
For high-efficiency metal cutting processing, the processed material, cutting tool, and cutting conditions are the three major elements. These determine the processing time, tool life and processing quality. The economical and effective machining method must be the reasonable choice of cutting conditions.
The three elements of cutting conditions: cutting speed, feed rate and depth of cut, these three directly affect the damage of the tool. The most suitable processing conditions are selected on the basis of these factors. Regular, stable wear and longevity are the ideal conditions. However, in actual operations, the choice of tool life is related to tool wear, dimensional changes to be processed, surface quality, cutting noise, and processing heat. When determining the processing conditions, it needs to be studied according to the actual situation. For difficult-to-process materials such as stainless steel and heat-resistant alloys, coolants or blades with good rigidity can be used.

Choose a tool reasonably
1. When roughing, choose a tool with high strength and good durability, so as to meet the requirements of large-back tooling and large feed when roughing.
2. When finishing turning, choose tools with high precision and good durability to ensure the requirements of machining accuracy.
3. In order to reduce the tool change time and facilitate tool setting, machine clamped knives and machine clamped blades should be used as much as possible.

Choose fixtures reasonably
1. Try to use general fixtures to clamp the workpiece, avoid using special fixtures;
2, the parts positioning datum coincide to reduce the positioning error.

Processing route
The processing route is the movement track and direction of the tool relative to the part during the processing of the index-controlled machine tool.
1. The machining accuracy and surface roughness requirements should be guaranteed;
2. The processing route should be shortened as much as possible to reduce the idle travel time of the tool.

Fixture installation points
       At present, the connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by a tie rod. The main points of hydraulic chuck clamping are as follows: First, use a moving hand to remove the nut on the hydraulic cylinder, remove the pull tube, and pull it out from the back of the spindle. Use a moving hand to remove the chuck fixing screw to remove the chuck.
