CNC Milling Machine Coordinate System Movement Direction
Ningbo Minsheng Machinery Co.,Ltd | Updated: Nov 01, 2017

In the CNC milling machine programming operation, in order to more clearly describe the movement of the machine form, CNC milling machine coordinate system and the direction of movement has been standardized.

First, the relative movement of CNC milling machine provisions

In order to allow the programmer to consider the machining process according to the part drawing without considering the specific movement of the workpiece and the tool on the machine tool. It is also stipulated that the tool is always assumed to move relative to the stationary workpiece coordinate system.

Second, the equipment coordinate system requirements

In the CNC milling machine on the processing of parts, the machine is running by the CNC system to issue instructions to control, in order to be able to ensure that the movement of the machine movement and movement direction, the coordinate system is called calibration coordinate system. CNC milling machine coordinate system using the right hand Cartesian coordinate system.

Third, the direction of CNC milling machine movement

The direction of movement of the CNC milling machine workpiece can show the direction of the distance between the tool and the workpiece. Where Z coordinate is the movement of the machine tool is determined by the spindle that transmits the cutting force, that is, the coordinate of the parallel and spindle axes is Z coordinate.

The X-coordinate is generally parallel to the clamping surface of the workpiece. Is generally horizontal. This is the main operating coordinate of the movement of the tool or workpiece positioning plane. The Y coordinate is the coordinate perpendicular to the X and Z axes. Additional coordinate systems, if there are other coordinates different from the three coordinates outside the basic Cartesian axes X, Y, Z, the additional Cartesian coordinates are specified as U, V, W and P, Q, R this way.
