Which is good for precision parts processing

Thus obtaining good CNC lathe machining quality. Stable cutting load. Based on calculations, stable cutting layer area and material removal rate can be obtained for non-standard stamping parts processing. Currently, many CAM software developed can adhere to stable cutting standards through the following measures. Maintain a balance between cutting load and tool damage speed to improve tool life and machining quality. Avoid suddenly changing the orientation of the cutting tool. Avoid burying cutting tools in the workpiece. When processing the mold cavity, it is advisable to avoid inserting the tool vertically into the workpiece, and instead choose the inclined downward cutting method at an angle of 30 °. Spiral knives should be selected as much as possible to reduce tool load; When processing mold cores, try to cut from the outside of the workpiece and then enter the workpiece. When using cutting tools to enter and cut workpieces, it is advisable to choose inclined or curved entry and exit, avoiding vertical entry and exit. The main goal of semi precision machining molds is to make the workpiece contour smooth and the surface precision machining allowance symmetrical. This is very important for tool steel molds because it affects the changes in the cutting layer area and tool load, thereby affecting the stability of the cutting process and the quality of the precision machined surface. According to the intermediate information of the machining model before precision machining, the remaining machining residue on the initial machining surface is unknown in automotive parts CNC machining. Therefore, the semi precision machining strategy should be optimized to ensure that there is uniform remaining machining residue on the workpiece surface after semi precision machining.
