During the machining process of CNC drilling and milling centers, there are many factors that affect the machining accuracy and productivity of parts, especially for complex parts. How to improve productivity while ensuring machining accuracy? Based on years of experience in CNC drilling and milling machining centers, Dahe Machine Tool Factory feels that using automatic programming can improve the utilization rate of machine tools, improve programming efficiency, and ensure programming quality. Therefore, CNC programming and parameter determination are very important.
CNC programming methods can be divided into two categories: manual programming and automatic programming.
1. Manual programming
Manual programming is the use of manual writing of workpiece processing programs. For workpieces with relatively simple geometric shapes, there are not many required programs, coordinate calculation is also relatively simple, and the program is not too long. In this case, using manual programming is both economical and timely. Therefore, manual programming is widely used in the machining of wheel feet composed of point straight lines and straight lines and arcs. However, when the contour of the workpiece is relatively complex, especially for non arcing curves, curved surfaces, ｏｒ long machining sequences, using manual programming is cumbersome and time-consuming, and prone to errors. It often leads to situations where manual programming cannot keep up with CNC drilling and milling machining, which affects the utilization rate of CNC drilling and milling centers. At this point, using automatic programming can effectively solve programming problems.
2. Automatic programming
Automatic programming, also known as computer-aided programming. During automatic programming, numerical control language is used to describe the relative motion, trajectory, and some machining processes of the cutting tool and workpiece during cutting. The programming only needs to use the specified numerical control language to program a brief workpiece source program, and then use the computer ｏｒ draw a diagram on the software. The programming system automatically completes the calculation of the motion trajectory and the programming of the machining program.
