Design difficulties:
When designing, it is necessary to avoid large-scale machining to avoid affecting the machining performance of the workpiece.
It is necessary to design elements such as ribs and ribs to improve the rigidity of the workpiece.
When designing, consideration should be given to the clamping structure, such as process holes, process tables, etc., and if necessary, sealing or removal should be carried out.
Difficulties in material selection:
Due to the tendency of thin-walled components to fail due to deformation during clamping or processing, high rigidity materials should be given priority when selecting materials.
For different materials, such as stainless steel, aluminum alloy, copper alloy, etc., suitable materials should be selected, and attention should be paid to the combination and use of materials.
Difficulties in machine tool equipment:
Machine tools need to have a high rigidity design and be equipped with various vibration reduction measures to reduce vibration.
The use of zero gap assembly with pre tightening can further improve the stability of the workpiece.
Difficulties in tool selection:
The selection of cutting tools should not only consider the degree of sharpness of the blade, but also the variation of strength to achieve optimal performance.
Difficulties in the processing process:
The rigidity of components in ultra-thin walled shell structures is poor, and slightly increasing cutting force during the machining process can cause bending deformation or even fracture of the parts.
To ensure the accuracy of the parts, it is necessary to effectively control internal stress deformation, clamping deformation, cutting force deformation, and cutting thermal deformation during the machining process.
The processing of certain special parts, such as deep inner ring grooves, narrow through holes, etc., may encounter difficulties in processing, which requires special clamping design and processing strategies.
Material processing difficulty:
Materials such as nickel based alloys are difficult to cut due to their high strength and toughness, resulting in fast tool wear and high cutting vibration
