Coordinate system of CNC turret punch
The use of CNC turret punch is different from ordinary punching machine. The platform of the fixed sheet material can be moved arbitrarily on the plane, while the punch is relatively fixed to the plane and can only move up and down. In order to complete the work, the control system is being programmed. Coordinate transformation is required when using software.
coordinate system
The coordinate system of the CNC turret punch press is an inherent coordinate system on the machine tool. Its origin is determined by the electrical and mechanical structure of the machine tool. In the CNC turret punch press, the origin of the machine coordinate system is determined by triggering the origin position sensor. When the machine is installed and fixed and debugging is completed, the origin position sensor is fixed, so the machine coordinate system determined by it is also fixed. The CNC turret punch machine coordinate system is the coordinate system of the machine operation. During the processing of the workpiece, the CNC system will convert any other coordinate system into the machine coordinate system for processing.
workpiece coordinate system
The workpiece coordinate system of the CNC turret punch press is used by the programmer during programming. It is translated by the machine tool coordinate system. The programmer can use any point on the workpiece drawing as the origin to establish the coordinate system. The workpiece coordinates established during programming In-system programming, without considering the actual position of the workpiece in the machine tool.
absolute and relative coordinate programming
Absolute coordinate programming and relative coordinate programming are based on workpiece coordinates. Both can be used in programming. Programmers can choose the type of coordinate system reasonably from the perspective of machining accuracy requirements and programming convenience. The CNC machining of the CNC turret punch press is based on the numerical calculation, that is, the calculation of the coordinates of the workpiece contour point. To describe the coordinates in digital quantities, it is necessary to establish a coordinate system to correctly grasp the definition of the coordinate axis and the movement direction of the CNC punching machine.
Through the transformation of the coordinates of the CNC turret punch control system, it can make it better to process the workpiece. If the transformation is not done, the work cannot be completed normally, which affects the work efficiency and work quality.
