The precise grinding combined control method is scientific and reasonable, has great adaptability to the variation of grinding wheel states and different material properties of the part, and can realize a target of carrying out the combined machining of the precise profile and the high-quality surface at a time.

Description

technical field [0001] The invention belongs to the category of mechanical methods, in particular to a precision grinding compound control method for relatively difficult-to-machine materials. Background technique [0002] Precision grinding is one of the important processing methods in the field of machinery manufacturing, and is widely used to process precision parts to obtain high-precision dimensions, contours and smooth surfaces. However, in recent years, with the development of new materials and advanced functional components, the proportion of difficult-to-machine materials such as superhard alloys, hard brittleness, and high plasticity in precision grinding applications has become higher and higher, and precision grinding equipment has become more and more difficult. It can meet the comprehensive index requirements of contour accuracy and surface quality, which leads to the widespread use of precision grinding and grinding and polishing manufacturing processes in ser...

Problems solved by technology

[0003] The above-mentioned segmented manufacturing process of precision grinding and grinding and polishing not only affects the grinding efficiency of difficult-to-machine parts, but also hinders the further improvement of the processing effect during the transfer process of the processed parts between equipment

For parts that are difficult to machine such as superhard alloys, hard and brittle, and high plasticity, there is still a lack of an efficient and compound precision grinding method
