Description
technical field [0001] The invention relates to a method for reducing the deformation of milling plastic materials, and belongs to the field of milling processing. Background technique [0002] Plastic materials have the advantages of low price, low density and easy processing, and are widely used in medical, aerospace, automobile manufacturing, food processing and other fields. However, the plastic material will generate more burrs during cutting, and at the same time, due to the small elastic modulus of the plastic material, a large amount of deformation will be generated, resulting in poor processing quality of the plastic material, thus failing to meet the requirements for use. Therefore, in order to improve the processing quality of plastic materials, it is necessary to optimize the processing technology and key cutting parameters of plastic materials. The deformation of plastic materials is mainly caused by excessive cutting force during the cutting process. Therefore...
