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

Five-axis linkage machining CNC technical problems:

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 related calculations of rotational motion, such as rotation angle stroke check, nonlinear error check, tool rotation motion calculation, etc. , the amount of information processed is huge, and CNC 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, programming and operation will be more complicated. Only through repeated practice can programmers and operators master the necessary knowledge and skills. Currently, the lack of experienced programmers and operators is a major obstacle to the popularization of five-axis CNC technology.

Five-axis simultaneous machining CNC technology has strict requirements on CNC interpolation controllers and servo drive systems. The CNC program verification and tool radius compensation of five-axis CNC are still insurmountable problems at the current technical level in my country.

Note: In the five-axis linkage NC 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.
