Abstract

The outer-blade slicing parallels the cut-off grinding and the creep-feed grinding in configuration. But it quite differs from them in that a very thin cutting blade is used, which undergoes an elastic deformation. From this viewpoint experimental studies have been carried out using GC grit blades 0.5mm thick and the following results are obtained. (1) An upward grinding force occurs in up-cut slicing process, which may be due to side face grinding following the elastic deformation of blade. (2) The upward grinding force has a usual sensitivity for grinding conditions. (3) Attritious wear predominates in the wheel wear under a small v/V ratio, while bond fracture does under a large v/V ratio. (4) The grinding performance of cutting edges on the side face has an important influence on chipping of the workpiece.
