Based on this work, the author has successfully developed the GrindSim software to set-up and optimise cylindrical grinding processes. Two possible criteria can be used to design a centerless grinding cycle: 1) Minimise the process cycle time or 2) Adjust the cycle to a previously established process time, minimising wheel wear.

Cycle Time = Net Production Time/Number of units made. Cycle Time = 550 minutes/ 45 dolls = 12,22 minutes/doll. Further observations about this Cycle Time example Currently, with a Cycle Time of 12,22 minutes, you're running 2,22 minutes behind for each doll — considering that your Cycle Time is longer than your Takt Time.
Here are some representative process data to illustrate a NCD creep-feed grinding calculation: Max. diameter of wheel: 16 inch. Min. diameter of wheel: 10.5 inch. Usable abrasive (radial): (16 – 10.5) / 2 = 2.75 inches. Dress amount per part (radial): 0.006 inch. Wheel life is then 2.75 / 0.006 = 458 parts per wheel.
A grinding wheel with SiC grains lapped with a carbide chip was applied for the infeed centerless grinding of the glass cylinders. The ground cylinders were visually transparent with no macro-cracks on the ground surface . The grinding time T g was set to 57 s (including a spark-out time of 5 s).
The purpose of this article is to demonstrate the calculation of wheel life in creep-feed grinding. Calculating wheel life is essential for forecasting wheel usage and the abrasive costs associated with a grinding process. In order to calculate the wheel life, it is essential to know which dressing methodology is being used.
The centerless process is commonly used for high volume production, and it's also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right).
