被动打磨通常也被称为高速打磨，又称为托磨或者滚磨，其英文全称为high speed grinding(简称HSG)。这种打磨技术是磨具无自转动力，通过调整磨具轴向与轨面的夹角和压力，在打磨车牵引下磨具在轨面形成非纯滚动的相对运动，从而实现磨具对轨面的磨削。X(θ) is the feed displacement of grinding wheel on the X-axis, and C is the rotation angle of workpiece on the C-axis. By taking the first derivative of X(θ), the X-axis feed speed of grinding wheel can be calculated.The data calculated by the model were incorporated into the CNC grinding machine. 2.3 Experimental system.

Grinding force is one of the significant parameters to assess machining behaviors. Fig. 2 shows the effects of grinding parameters on the F n ’ and the F t ’ under various high-speed grinding steps. The results show that higher F n ’ and F t ’ can be seen at higher v w and a p under different high-speed grinding steps, as expected. TheLow-speed grinding tests are performed for pyrite and quartz at three different feed sizes (-3.35+2.36 mm, -2.36+1.7 mm, and -1.7+1.18 mm).

The second set was conducted with a grinding speed ranging from 60 to 260 m/s and is referred to as high-speed grinding tests (HSGTs). All CGTs were performed in down cut plunge surface grinding mode using a Teknoscuola SRT600 grinding machine.

Then, the influence of headstock rotating speed and grinding depth on thread surface quality was studied under the high-speed grinding condition with grinding wheel linear speed of 80 m/s. The test factors and levels are shown in Table 2. The grinding depth range is 0.01–0.05 mm, and the headstock speed range is 1–5 rpm.High-speed grinding is newly developed as a powerful tech-nique for achieving good component quality combined with high productivity [1, 2]. The increase in grinding speed can reduce the undeformed chip thickness, thus resulting in a reduction in grinding forces, wheel wear, and in workpiece surface roughness [2].

Abstract. High-speed grinding is an important process for high-performance machining of advanced materials due to its capability for high-efficiency and excellent surface integrity. In this chapter we introduced the fundamentals of high-speed grinding, followed by a review of our practices of high-speed grinding in recent years.Grinding is a choice for obtaining high surface quality and closer dimensional tolerance. For meeting this objective economically, the material removal rate (MRR) must be sacrificed to certain extent. The MRR could be increased by either increase in wheel speed, depth of cut, and feed rate. An increase in MRR increases the surface High Speed Grinding of EN31 Steel with Alumina Nanofluid
