Edge surface grinding of CFRP composites using rotary

The conventional surface grinding (CSG) usually generates surface damages, leading to reduced service life and load-carrying capability of the parts. 2.2 Surface roughness modeling. The Rayleigh parameter σ of UCT under different working conditions is determined by the above mathematical model, and it is added to the surface roughness model.

Face grinding with the end surface of wheel was carried out for 100 paths. Three types of coolant supply were tested—namely, dry grinding, coolant supplied with external nozzle, and internal coolant supplied through the grinding wheel.The double disc straight groove grinding method for precision machining of cylindrical roller rolling surface was proposed by Ren’s team [ 101 ]. The machining principle and the physical layout are shown in Fig. 19. This method employs two grinding discs, one on top and the other on the bottom.Advance on surface finishing technology of precision bearing

Design and evaluation of an internal-cooling grooved grinding wheel

1. According to the principle of internal cooling, an internal cooling bowl-type grinding wheel has been developed, which sets the internal-channel outlet in the center of the abrasive zone to enhance the flowability of the coolant. The internal structure of the grinding wheel is optimized as a two-stage cavity with eight transitional holes by CFD.In view of the defects such as material bonding, work hardening, and tensile residual stress on the ground surface due to excessive temperature during grinding of superalloys, an internal-cooling grooved grinding wheel was designed and fabricated. Several abrasive patterns with different geometries (random, oblique, circular staggered, Performance of the internal-cooling grooved grinding wheel with

Introduction. Grinding is applied for surface finishing and to achieve high material removal rates (MRR). For both, a suitable coolant supply is mandatory to achieve the required workpiece quality, to avoid thermal damage and to reduce tool wear. As a consequence, the coolant supply in grinding has always been a well-researched topic [1].Improved coolant supply through slotted grinding wheel

Residual stress in grinding ScienceDirect

Conclusions. 1. The grinding coefficient B combining power density and wheel/workpiece contact time was developed to predict residual stress in surface grinding. 2. A linear correlation between coefficient B and maximum residual stress was found experimentally. It was confirmed for several workmaterials.Abstract. Metal is removed from the workpiece by the mechanical action of irregularly shaped abrasive grains in all grinding operations. This article discusses three primary components of grinding wheels, namely, abrasive (the cutting tool), bond (the tool holder), and porosity or air for chip clearance and/or the introduction of coolant.Grinding, Honing, and Lapping Machining ASM Digital Library
