Small CNC lathe manufacturers introduced CNC milling machine coordinate system
In the numerical control milling machine programming operation, in order to be able to more clearly describe the movement of machine tools, CNC milling machine coordinate system and movement direction has been standardized.
1, CNC milling machine relative motion requirements
In order to allow the programmer without considering the machine tool and tool specific movement, in accordance with the parts drawings to determine the process. In addition, always assume that the tool moves relative to the stationary workpiece coordinate system.
Equipment coordinate system
CNC milling machine in the processing of parts, machine tool operation is issued by the CNC system to control the order, in order to ensure that the movement of the machine movement and direction of movement, the coordinate system is called the calibration coordinate system. Coordinate system of CNC milling machine adopts right hand Cartesian coordinate system.
3, CNC milling machine direction of movement requirements
CNC milling machine workpiece machining direction of movement can show the direction of the distance between the tool and the workpiece. Where the Z coordinate is the machine tool movement is determined by the transfer of the cutting force of the spindle, that is parallel to the axis of the axis coordinate Z coordinate.
X coordinates are generally parallel to the workpiece clamping surface. Generally horizontal. This is the main running coordinate of the movement of the tool or workpiece in the plane. The Y coordinate is a coordinate perpendicular to the X and Z axes. Additional coordinate systems, if there are other coordinates of these three coordinates in addition to the basic Cartesian axes X, Y, Z, the additional Cartesian coordinates are specified as U, V, W and P, Q, R this way.
