The technicians of JC-Tooling have shared information about the different methods and processes used in machining mechanical drawings, which is helpful in understanding the CNC part machining process. These methods can be chosen depending on the complexity of the part, accuracy requirements and the production process. Below is a summary of the machining methods and processes you have mentioned:
Tool Focused Sequencing Method: This method divides the process based on the tools used. A tool to complete all the machining processes that can be done on the part, and then gradually use other tools to avoid frequent tool changes, improve machining efficiency and reduce positioning errors.
Roughing and finishing sub-processing method: first roughing or semi-finishing, and then finishing operations. In the machining process, attention should be paid to setting up a buffer time between roughing and finishing, in order to allow the deformation of the parts to be restored, improve machining accuracy and finished product qualification rate.
According to the machining part of the sequential method: This method is based on the complexity of the machining part and precision requirements to divide the process. Simple geometric shapes are processed first, and then the complex parts are processed, or low-precision areas are processed first, and then the high-precision parts are processed.
As for the process of CNC parts machining, you mentioned different ways of handling different types of parts. For small parts, methods such as punching and CNC machining can be used; while for large parts, more processes may be required, such as opening punching, burning, sanding, painting and assembly.
In short, the choice of machining methods and the design of the process flow depend on the nature of the part, its requirements and the production environment. Understanding these different methods and processes can help improve machining efficiency and product quality.
