High Speed Grinding

Increasing the structural reliability at ultra-high-speed grinding is an important problem because it defines safety of metalworking. The purpose of work is to achieve the cutting speed up to 400-500 m/s by developing a new design of the grinding wheel with the possibility of using different grinding materials. Grinding wheel design for ultra-high-speed grinding was developed based on calculations carried out using the tear design method, which allows determining the maximum possible circumferential speed, and finite element method used to determine the equivalent stresses, plastic deformations, circumferential and radial movements . The possibility of development of a grinding wheel design for ultra-high-speed grinding has been tested experimentally. The developed designs of grinding wheels show may poddibly be used on super high-speed technological equipment for processing of parts made of hard-to-machine materials. Calculations and comprehensive experimental tests of the design of grinding wheels for ultra-high-speed grinding carried pit in this work allow determining the serviceability and the maximum possible cutting speed and provide useful information for the further development of grinding tools.

Grinding Conditions

There are strong demands for a machining process capable of reducing the surface roughness of sliding parts, such as auto parts and other components, with high efficiency. In this work, we attempted to grind hardened steel to a mirror-like surface finish with high efficiency using an ultra-high speed grinding process. In the present study, we examined the effects of the work speed and the grinding wheel grain size in an effort to optimize the grinding conditions for accomplishing mirror-like surface grinding with high efficiency. The results showed that increasing the work speed, while keeping grinding efficiency constant, was effective in reducing the work affected layer and that the grinding force of a #200 CBN wheel was lower than that of a #80 CBN wheel. Based on these results, a high-efficiency grinding step with optimized grinding conditions was selected that achieved excellent ground surface quality with a mirror-like finish.

The future development of the manufacturing is using VR technology to make the machining simulation before the actual machining process made. The machining simulation of Ultra High-speed Grinding Machine Tool is researched in this paper. Firstly, using UG/NX software and VRML, the geometric modeling of machine tool is modeled. Secondly, through using Java and Javascript language, the operation and display of machining process of ultra high-speed grinding are realized. The main technologies include NC codes compiling, collision detection and material removal. Thirdly, the example of machining simulation using virtual ultra high-speed grinding machine tool can be obtained in the paper. Compared to other CNC machining simulation methods, the method in the paper has reality display, rich features, a good man-machine interaction, etc., and it does not rely on expensive CAD/CAM software. The system files generated by the machining simulation have the small size and can be transferred on the network easily.
