1.What is 3+2 positioning processing

When a 3-axis milling program is executed, the two rotary axes of the 5-axis machine are used to hold the cutting tool in a tilted position. This is where the name 3+2 machining technology comes from. This is also called positioning 5-axis machines because The fourth and fifth axes are used to orient the tool in a fixed position, rather than continuously during machining.

The principle of 3+2 positioning machining is essentially the realization of the three-axis function at a specific angle (that is, "positioning"). Simply put, when the machine tool rotates the angle, it is still processed in the ordinary three-axis manner.

2.What is 5-axis simultaneous machining

According to ISO regulations, when describing the movement of CNC machine tools, a left-handed Cartesian coordinate system is used; the coordinate axis parallel to the main axis is defined as the Z axis, and the rotation coordinates around the X, Y, and Z axes are A, B, and C, respectively. Usually five-axis linkage refers to the linear interpolation motion of any 5 coordinates in X, Y, Z, A, and B.

3.The difference between 3+2 positioning and 5-axis simultaneous

3+2 positioning machining and 5-axis simultaneous machining are suitable for different industries. 5-axis simultaneous machining is suitable for curved surface machining, and 3+2 positioning machining is suitable for plane machining.
