In-process monitoring of the relevant physical properties of the ground surface such as the texture state of surface and sub-surface layer, residual stress and grinding burn is decisive to guarantee the manufacturing quality of the machine parts. But at the present time it is difficult to realize in production.In surface grinding experiments of casehardened 16MnCr5 a close correlation between the related grinding power Pc" and the maximum average temperature Tmax in the contact zone between workpiece and grinding wheel is determined. The texture state of surface and sub-surface layer and the occurrence of grinding burn are mainly influenced by this contact zone temperature. To identify these states, the comparatively simple and measurable related grinding power Pc" is used. The ground surface layer maintains the normal acicular martensite if Pc" does not exceed a specific threshold PcI". In case this value PcI" is exceeded, the slope of the tangential grinding force curve increases. If the related grinding power exceeds a second threshold PcⅡ", a decoloration of the ground surface due to the grinding burn occurs.The texture state and the microhardness of surface and sub-surface layer verify the different workpiece conditions. The results indicate that the related grinding power Pc" can be proposed as a reliable characteristic quantity for in-process monitoring to estimate the texture state of surface layer and grinding burn in production.

磨削过程中零件表层物理特性如金相组织、表面残余应力、磨削烧伤等的过程监测是为确保零件制造质量的重要课题,但目前尚难于在生产过程中实现。 在平面磨床上进行大量磨削16MoCr5表面硬化钢的试验后发现,单位面积磨削功率P″_c与砂轮—工件接触区最高平均温度T_(max)间有极好的函数对应关系。而磨削表层金相组织状态和发生烧伤主要决定于接触区的温度,因而可以应用相对容易测量计算的单位面积磨削功率P″_c来识别这些状态。如果P″_c没有超过某一特定的临界值P″_(cⅠ)时,磨削表层保持正常的针状马氏体组织。在超过P″_(cⅠ)的情况下,切向磨削力的斜率增加,当P″_c又超过第二临界值P″_(cⅡ)后,磨削表面由于烧伤而出现了变色层,表层金相组织和显微硬度证实了工件的这些不同的情况。试验结果表明,单位面积磨削功率P″_c,可以作为磨削过程监测和预报表层金相组织状态和磨削烧伤的可靠的过程特征参量,在生产实践中应用。

An experimental platform for grinding rough surfaces was setup. It consists of a MOTOMAN robot, 6D force (moments) measuring system and vibration measurement. The grinding forces and vibrations during the processes for grinding rough surfaces were measured. The resemblances and differences between the rough surface grinding and normal surface grinding were analyzed based on the experimental data. The significant deference between rough surface grinding and ordinary grinding is that the tangent force in rough surface grinding can be much larger than normal force. It depends on the features of the material and the roughness of the surfaces. The rougher the grinding surface, the larger the tangent force induced.

组建了由MOTOMAN机器人、六维力 (力矩 )测量系统和振动测量组成的粗糙表面磨削实验平台 ,进行了磨削力的测量及振动的测试 ,分析了MO TOMAN磨削机器人系统的磨削力及振动响应。结果表明 ,粗糙表面磨削与普通表面磨削的显著区别是 :切向磨削力与法向磨削力不成比例 ,切向磨削力可能比法向磨削力大很多 ;影响切向磨削力大小的最主要因素是被磨削材料的表面质量 ,表面越粗糙 ,则切向磨削力越大
