Five-axis linkage machining is a mode of CNC machine tool machining, which adopts linear interpolation movement of any five coordinates in X, Y, Z, A, B, and C. Below, the editor will introduce you to more knowledge about five-axis linkage machining.

Technical problems of five-axis linkage machining CNC technology:

Five-axis CNC programming is abstract and difficult to operate

Generally speaking, in addition to linear motion, five-axis CNC programming also needs to coordinate calculations related to rotary motion, such as rotation angle stroke check, nonlinear error check, tool rotary motion calculation, etc. , the amount of information to be processed is very large, and the NC programming is extremely abstract. The operation of five-axis simultaneous machining CNC machining is closely related to programming skills. If the user adds special functions to the machine tool, the programming and operation will be more complicated. Only with repeated practice can programming and operators acquire the necessary knowledge and skills. At present, the lack of experienced programming and operators is a major obstacle to the popularization of five-axis CNC technology.

The five-axis CNC machining technology has strict requirements on the CNC interpolation controller and servo drive system. The five-axis CNC program verification and tool radius compensation are still problems that cannot be overcome by the current technical level in our country.

Note: In the five-axis linkage CNC program, the tool length compensation function is still valid, but the tool radius compensation is invalid. The ultimate solution to this problem depends on the introduction of a new generation of CNC systems that can recognize workpiece model files in common formats (such as STEP, etc.) or CAD system files.
