摘要:
以40CrNiMo钢为研究对象,对原有磨削工艺进行优化,探讨减少工作台进给次数、去掉半精磨工艺对磨削质量的影响.结果表明:原有粗磨+半精磨+精磨工艺改为粗磨+精磨两道工艺是可行的,且在保持总磨削余量一定的条件下,通过减少工作台进给次数的方法可以降低粗磨过程多次走刀造成的磨削表面硬化,同时提高了加工效率;粗磨产生的磨削表面硬化对降低半精磨、精磨后的磨削表面粗糙度有利,但表面硬化伴随着磨削亚表层金相组织变化和残余应力等不利因素.
Abstract:
The effects of reducing frequency of strokes and eliminating semi-fine grinding process on the grinding quality of 40CrNiMo gear steel were investigated. It was found removal of the semi-fine grinding process from existing coarse/semi-fine/fine processing sequence is feasible and at a constant total grinding allowance,a decrease of strokes number can successfully reduce surface hardening and subsequently improve the machining efficiency. It was also evidenced that the surface hardening left by coarse grinding can reduce the surface roughness of semi-fine and fine grinding however the undesirable sub-surface damage and residual stress would associate. These findings are of practical significance for optimization of grinding process.
