During the processing of the linear stage, the stage base will be easily deformed. This is mainly because the forces are mutual, and any object will produce stress when it is stressed. The deformation of linear stage will affect the straightness and parallelism of the stage, and the longer the stage is, the greater the impact will be, which will not only affect the assembly, but also affect the normal operation of the whole stage. The following distribution can effectively avoid the deformation of linear stages.
1. Reducing the cutting depth of aluminum profile can effectively reduce the generation and stress of aluminium scrap and reduce the heat and deformation.
2. Use a sharp tool, and the tool with severe wear will affect the cutting force when processing aluminum profiles, which will increase the heat generated and make it easy to roll the edge.
3. The use of cutting fluid can play the roles of lubrication, chip removal, cooling and so on, which can effectively avoid the phenomenon of thermal expansion, and at the same time, it can also avoid the damage to the workpiece surface caused by aluminium scrap.
4. Optimizing the tool path and machining sequence, and optimizing the feed route can avoid the deformation that affects the machining when the cutting margin is large, and the uniform machining sequence can effectively avoid the situation of concentrated high temperature.
