What are the main factors that affect the accuracy of machining workpiece in the precision manufacturing?
In the precision manufacturing, the impact of the workpiece machining accuracy of the main elements are listed below:
(1) Tool dash shape error and its equipment error on the machine.
(2) The workpiece on the machine tool error.
(3) Machine tools in the processing of the existing errors.
(4) During the cutting process, the vibration, elastic deformation, thermal deformation and tool wear of the machine tool-tool system.
(5) Machine dash error.
(6) Transmission error of machine tool chain.
