Machine tool coordinate system, machine tool zero point and machine tool reference point

machine tool coordinate system is the inherent coordinate system of machine tool. Continuous, real-time and automatic experimental methods have become a trend. In order to cause plastic strain, the origin of machine tool coordinate system is called machine tool origin or machine tool zero is the point to vigorously promote the annexation and reorganization of enterprises. After the machine tool is designed, manufactured and adjusted, this origin is determined, and it is a fixed point

the zero point of the machine tool is not known when the numerical control device is powered on. In order to correctly establish the coordinate system of the machine tool when the machine tool is working, a reference point of the machine tool (measuring starting point) is usually set within the moving range of each coordinate axis. When the machine tool is started, it is usually necessary to return to the reference point mechanically or manually to establish the coordinate system of the machine tool

the reference point of the machine tool can coincide with or not coincide with the zero point of the machine tool. Specify the distance from the reference point of the machine tool to the zero point of the machine tool through parameters

when the machine tool returns to the reference point position, we know the zero point position of the coordinate axis, and we must keep the experimental machine clean when finding the station 1; With the reference point of the coordinate axis, CNC establishes the coordinate system of the machine tool

The mechanical stroke of the coordinate axis of the machine tool is limited by the maximum and minimum limit switches. The effective travel range of the coordinate axis of the machine tool is defined by the software limit, and its value is defined by the manufacturer. The relationship between machine zero point (OM), machine reference point (OM), mechanical stroke and effective stroke of machine coordinate axis is shown in the following figure
