Next, determine the inches per minute feedrate: 458 times 0.008 is 3.664 ipm. Finally, determine the time required in minutes: 3 inches of motion divided by 3.664 ipm is 0.8187 minutes. To determine the number of seconds, divide 0.8187 by 0.01666 - this comes out to 49.141 seconds. Fixed diameter machining versus changing-diameter …

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, …
When it comes to machining time calculation, the formula is as follows: Machining Time = Length of Cut (mm) / Feed (mm per revolution) x Revolutions Per Minute. Revolutions Per Minute = 1,000 x Cutting Speed (mm per minute) / π x Diameter of Rod (mm) Depending on the project, you may need to replace millimeters with inches.
Creepfeed/surface grinding: Increase wheel speed. This is a good starting point. However, be sure the wheel is rated to run at the new speed. The maximum operating speed (MOS) will be stated on the side of the wheel. Reduce feed rate. Reduce depth of cut. Increase the number of spark-out passes.
