Due to the high precision and high speed of spindles for machining centers, thermal issues cannot be avoided. The temperature rises of the spindle shaft, which is the rotating component, causes issues such as increased thermal displacement in the tool axis direction and an increase in friction torque, leading to limitations on the spindle speed. Heat removal or heat diffusion methods are effective in reducing the temperature of the spindle shaft. The former method of removing heat from the rotating shaft requires complex peripheral devices for cooling. Here, the latter method of diffusing heat is examined. Specifically, a method for reducing the temperature of the high-temperature part and the temperature difference generated in the shaft will be examined.

Aiming at the problem that the basic impedance control has great impact force and is difficult to cope with environmental changes when it contacts with the tooth surface of worm gear, an adaptive impedance control method based on genetic algorithm was proposed. The influence law of spindle speed, feed speed and grinding force on the surface quality of worm gear tooth surface is analyzed. With material removal rate as the optimization objective, an optimization model of grinding process parameters is established based on particle swarm optimization algorithm, and the optimal grinding process parameters for industrial robot grinding worm gear tooth surface knife marks are obtained: Spindle speed (n=3087.82r/min), Feed speed (vf=0.51mm/s), Normal grinding force (F=19.9N). The experimental results show that the roughness of worm gear tooth surface is increased from 0.941 to 0.719 by using the optimized grinding process parameters. Moreover, this method can effectively suppress the external force influence of industrial robots in the process from free space to constrained space, and the force fluctuation is significantly reduced after contact stabilization, and it has stronger environmental adaptability and force control performance.
