First of all, the design and development of the processing process are carried out
Before CNC machining, it is first necessary to design and formulate the processing process of the product. According to the requirements and functions of the product, the designer uses CAD (computer-aided design) software to design the product. Then, the process engineer formulates the machining process according to the shape, material and processing requirements of the product, including the selection of appropriate cutting tools, cutting parameters, cutting paths, etc.
Secondly, the processing program is written
The machining program is the core of CNC machining, which contains the action instructions, cutting parameters, cutting paths and other information of the machine tool. Writing a machining program requires the use of CAM (Computer Aided Manufacturing) software to convert the design files of the product into a machining program. When compiling the processing program, it is necessary to consider the cutting performance of the material, the rationality of the process and other factors to ensure the efficiency and quality of the processing process.
Then, machine set-up and tool set-up are carried out
Before CNC machining, the workpiece needs to be clamped on the machine and the appropriate tool is selected for cutting. Machine tool clamping is the process of fixing a workpiece on a machine tool, which needs to take into account the shape, size and machining requirements of the workpiece. Tool set-up is the process of attaching a tool to a machine and requires the selection of the right tool type and size, as well as the correct installation. The accuracy and stability of machine clamping and tool clamping have a significant impact on machining accuracy and efficiency, so they need to be carefully adjusted and checked.
Next, the machining operation is carried out
After the machine clamping and tool clamping are completed, the CNC machining operation can begin. The operator inputs the written machining program into the CNC machine controller, and then through the instructions of the controller, the machine tool cuts according to the path and speed specified in the program. In the machining process, operators need to monitor the machining status and adjust the cutting parameters and tools in time to ensure the quality and efficiency of the machining.
Finally, the processing inspection and trimming are carried out
After CNC machining, the machined parts need to be inspected and trimmed. Inspection can be carried out with measuring tools and equipment to verify that the machined part meets the requirements. Dressing is the process of trimming, grinding or polishing the machined parts to eliminate possible processing defects and improve the accuracy and surface quality of the machined parts.
