Embodiment Construction

[0097] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0098] Such as image 3 As shown, an optimization method of plunge grinding process parameters based on the grinding removal rate model, the specific steps are:

[0099] 1. Establish the theoretical model of plunge grinding removal rate

[0100] Due to the elastic deformation of the plunge grinding system, the actual feed rate in the grinding feed stage always lags behind the feed rate set by the NC command. During the plunge grinding feed process, due to the normal grinding force F n The resulting elastic deformation δ can be expressed as:

[0101]

[0102] In the formula, F n is the normal grinding force at the contact point between the grinding wheel and the workpiece, δ is the elastic deformation, k e is the equivalent stiffness of the system.

[0103] Normal grinding force F in plunge grinding n and actual feed speed Subject to a certai...

Description

technical field [0001] The invention relates to a method for optimizing process parameters of plunge grinding based on a grinding removal rate model. Background technique [0002] Plunge grinding is often used to grind workpieces with high quality requirements. Although it has been widely used, for plunging grinding, the process is complicated and there are many influencing factors, so it is still one of the cutting processes that have not been deeply understood. . The process parameters of plunge grinding not only directly affect the processing efficiency, but also have a great influence on the quality of the ground surface. In recent years, many researchers have carried out a lot of research work on the optimization of grinding process parameters and related applications. Aiming at various situations of plunge-cut grinding process, different mathematical optimization models of process parameters have been proposed and verified under relevant experimental conditions. The ...
