It is said that CNC processing is good, the good reason is here.
CNC machining,also known as CNC machining,requires process analysis of the machined parts before programming,drafting the machining plan,selecting the right tool,and determining the amount of cutting.In programming,some process problems such as tool points and machining routes need to be processed.Therefore,process analysis in programming is very important.When machining a part on a general machine tool,the procedure or process card is used to specify the operating procedure for each process,and the operator processes the part according to the steps specified on the process card.When machining parts on CNC machine tools,the entire process,process parameters and displacement data to be processed are programmed into a program to control machine tool processing.The machining process of CNC machine tools is basically the same in principle as the machining process of ordinary machine tools,but the whole process of CNC machining is automatic,so it has its own characteristics:
1.The content of the process is complicated.This is because the numerical control machine tool is more expensive than the ordinary machine tool.If only the simple process is economically uneconomical,the more complicated process is usually arranged on the numerical control machine tool,even the process which is difficult to complete on the ordinary machine tool.
2.The arrangement of the work steps is more detailed.This is because the problems that need not be considered in the processing technology of the ordinary machine tool,such as the arrangement of the work steps in the process,the determination of the tool point,the tool change point and the processing route,etc.The machine tool processing technology can not be ignored.
3.Rely on the process to complete all processes.
4.The CNC machining program is the instructional document of the CNC machine tool.
5.The CNC machine tool is controlled by the program instructions,and the whole process of machining is automatically performed according to the program instructions.
6.The CNC machining program not only includes the process of the parts,but also the process parameters necessary for the completion of the process,such as the cutting amount,the feed route,the tool size number and the movement process of the machine tool.
7.CNC machining has high efficiency,high machining precision,low labor intensity and strong adaptability to different workpieces.
