1. Reduce transmission error in the transmission chain
(1) Fewer transmission components, shorter transmission chain, and higher transmission accuracy;
(2) Adopting a reduced-speed transmission is an important principle for ensuring transmission accuracy, and the closer the transmission pair is to the end, the smaller its transmission ratio should be;
(3) The precision of the end components should be higher than that of other transmission components.
2. Reduce tool wear
(1) The tool must be re-sharpened before the tool size wear reaches the rapid wear stage
(2) Use dedicated cutting oil for sufficient lubrication
(3) The material of the cutting tool should meet the process requirements
3. Reducing the stress deformation of the process system
(1) Improve the rigidity of the system, especially the rigidity of the weak links in the process system;
(2) Reduce the load and its variations
4. Reduce thermal deformation of the process system
(1) Reduce heat generation and isolate heat sources
(2) Equilibrium temperature field
(3) Adopt reasonable machine tool component structure and assembly benchmark
(4) Accelerate to achieve heat transfer equilibrium
(5) Control the ambient temperature
5. Reduce residual stress
(1) Add a heat treatment process to eliminate internal stress;
(2) Reasonably arrange the technological process.
The above are methods to reduce errors in processing workpieces. Reasonable arrangement of processes can effectively improve the precision of the workpieces.
