1. Reasonably design cut-in and cut-out routes
When using a CNC machining center to process parts, design the cut-in and cut-out route to optimize the cutting angle of the machine tool. In order to achieve the effect of reducing the marks of the cutter and ensuring that the quality of the surface is not affected, it is necessary to plan the cutting of the cutter. The cutting point of the tool is mainly from the periphery of the part to ensure a smooth contour surface. The cutting tool should be as small as possible to choose the feed rate, let it keep cutting at a slow speed, so that the cutting transition smoothly, so as to ensure the cutting quality.
2. Correctly choose the cutting method
When using a CNC milling machine for processing, there are two ways of down milling and up milling. The finishing effect of down milling is better than that of up milling. Therefore, in the processing of parts, when conditions permit, try to choose down milling to improve the surface quality of the parts. In the turning of shaft parts, it is also necessary to select the same turning tool as much as possible for the machining of different journals, so as to better reduce the marks caused by the tool connection.
3. Use new high-efficiency tools
The efficiency and performance of CNC machining centers are inseparable from tools. For the machining of parts with high precision requirements, not only the perfect technological process must be paid attention to, but also the selection and use of new high-efficiency tools. Today's tool optimization design can use new tool concepts, which can more reasonably solve the problems of machining safety, accuracy, surface roughness, high-speed cutting, and the ability to optimize cutting paths.
4. Use the best CNC machining program
Optimize the CNC machining program to provide the best CNC data for processing, which can better improve the quality. Compared with ordinary machine tools, CNC machining centers not only require operators to have a higher level of operation in the processing of parts, but also need to have a higher level of programming and process analysis. In order to ensure machining accuracy, it is necessary to optimize and streamline the program in order to improve production efficiency.
