In a certain grinding operation, the grade of the grinding wheel should be ‘‘M'' (medium), but the only available wheel is grade ‘‘T'' (hard). It is desired to make the wheel appear softer by making changes in cutting conditions. What changes would you recommend?
An aluminum alloy is to be ground in an external cylindrical grinding operation to obtain a good surface finish. Specify the appropriate grinding wheel parameters and the grinding conditions for this job.
