The positioning accuracy of CNC machine
The positioning accuracy of CNC machine is refers to the position accuracy of each axis of the CNC machine tool under the control of CNC device. The positioning accuracy of CNC machine can also be understood as the motion accuracy of machine tools. The position accuracy of the common machine tool is determined mainly by the reading error, while the movement of the CNC machine tool is realized by the digital program instruction, so the positioning accuracy is determined by the CNC system and the mechanical transmission error. The motion of the moving parts of the machine tool is completed under the control of the numerical control device. The precision of the moving parts under the control of the program instruction directly reflects the precision that the parts can reach. Therefore, the positioning accuracy is an important test.
