1. Determination of the processing route
Proper and concise processing routes are the basis for ensuring processing quality and efficiency. When selecting the machining route of the part, the principle of determining the machining route must be followed in order to achieve the purpose of improving production efficiency. The principle of determining the processing route is mainly: it should ensure the processing precision and surface roughness of the parts, and the efficiency is high; the processing route should be minimized as much as possible, so that the program segment can be reduced and the tool idle time can be reduced. ; should make the numerical calculation simple, the number of blocks is small, to reduce the programming workload. In addition, when determining the machining route, it is also necessary to consider the machining allowance of the workpiece and the rigidity of the lathe and the tool, and determine whether it is a single pass or a multiple pass to complete the machining. At the same time, it should be done once in a single clamping, multi-directional processing, one-time processing. In this way, the number of times the workpiece is mounted can be reduced, and the time for handling and clamping can be effectively shortened. In this way, the processing efficiency can be effectively improved and the positional accuracy requirements of the parts can be well ensured.
2. Choose the right tool
The selection of the tool should take into account the processing capability of the CNC lathe, the content of the process, and the material of the workpiece. The tool selected by CNC lathe not only requires high hardness, high wear resistance, sufficient strength and toughness, high heat resistance and good processability, but also requires dimensional stability and convenient installation and adjustment. Therefore, CNC machining tools should be manufactured with new high-quality materials, and the tool parameters should be optimized so that the size of the tool matches the surface size and shape of the workpiece being machined.
