Thrufeed Centerless OD Grinding: Parameters and Troubleshooting
With increased angle, quicker rounding occurs, but it also weakens the blade rigidity. The most common top angle used in centerless grinding is 30 degrees. As the diagram below indicates, lower angles are used when grinding heavy workpieces, which help minimize vibration. Workrest top angles typically range from 45 degrees down to 20 …

Cycle Time for Centerless and Internal Grinding
Allow enough stock for the grinder to set up and kiss-off the part. Leave only enough stock to clean up all surfaces with a safety factor agreed on with the grinder operator. Remember to have good centers and surfaces to hold onto for ID and OD grinding. Work out the stock allowance for centerless grinding with the CG operator also.

Speed Distance Time Calculator
distance = speed x time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time. distance = rate x time. To solve for speed or rate use …
