SCZY have rich experience on CNC milling parts. But how to conduct the CNC milling machining process?

First, we need to compile the processing program of the workpiece. If the processing program of the workpiece is long and complicated, it is best not to program on the machine tool, but to use a programming machine or computer programming, in order to avoid occupying the machine for long time, and it should also be used for short programs.

Fourth, we should adjust the processing program according to the storage medium of the program, which it can be input by paper tape reader, cassette tape machine, programming machine or serial communication. If it is a simple program, it can be input directly on the CNC control panel using the keyboard. If the program is very simple and only one piece is processed, there is no need to save the program. The MDI method can be used to input and process section by section. In addition, the workpiece origin, tool parameters, offsets, and various compensations used in the program must also be input before processing.

Fifth, we need to edit the program. If an input program needs to be modified, the program is edited. At this point, put the mode selection switch in the edit position, and use the edit key to add, delete and change. See the corresponding instruction for editing methods.
Sixthly, if the machine is locked, the program will be run. This step is to check the program. If there is any error, it is necessary to edit it again.

Seventh, the continuous movement or manual wheel movement of the machine tool is adopted for loading the workpiece and aligning the tool. Make the starting point to the beginning of the program, and set the tool benchmark.
Eighth, start to coordinate feed for continuous processing generally uses programs in the memory for processing. This method has a lower failure rate than the program on paper tape. The feed rate during processing can be adjusted by the feedrate override switch. During processing, you can press the feed hold button to pause the feed movement, observe the processing conditions or perform manual measurement. Press the cycle start button again to resume processing. To ensure that the program is correct, it should be checked again before processing. In the milling process, for the plane curve workpiece, a pencil can be used instead of the cutter to set the contour of the workpiece on the paper, which is more intuitive. If the system has a tool path simulation function, it can be used to check the correctness of the program.
Ninth, operation display utilize the various screens of CRT to display the position of the workbench or tool, the program and the state of the machine tool, so that the operator can monitor the processing situation.
Tenth, after the program output processing, if the program is necessary to save, it can be left in the CNC memory. If the program is too long, the program in the memory can be output to an external device.
Finally, in general, the machine tool should be shut down before shutting down the system. Any need for customed CNC milling parts, CNC turning parts, Grinding Machining Parts, just feel free to contact with us. We will give you the best solution within 24 hours.
