Abstract The method of calculating the surface roughness parameters for an external cylindrical grinding is considered. The offered calculation relations are taken account of production mode parameters the grain size of the grinding wheel and the change of state of the tool working surface during machining.
Jun 08 2010 New to Cylindrical Grinding. Hi All This is my first post so please be gentle We have just purchased a second hand 1993 CNC Tschundin Pl-31 cylindrical grinder with Fanuc OG control. We currently make a few small shafts that we have been sending out for grinding we wanted to bring them in house. Ill be honest I have no clue in the best .
In the grinding process due to the elastic deformations of grinding machine and grinding wheel the ground depth of cut is smaller than the applied depth of cut. Consequently the ground depth of cut has to be controlled in spark-out grinding process. However the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint in this study using specific .

Feb 28 2008 Lets say I have a 20 workpiece mounted in the center on a cylindrical grinder with a 60 table with center pivot. I indicate the left and right extremities closest to zero and take a small .003 cut. Grinding wheel removes material on entire length. I take a micrometer to it and get a .010 taper exagerated of course. My question is this
