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 grinding force obtained by measured grinding

The plus symbol (+) in the denominator is used for external grinding while the minus symbol (-) is used for internal grinding. This means that you can apply similar practices to similar operations to achieve the same result.

Cycle Time Throughput Yield The time to complete a task or collection of tasks. The desired process throughput is inverse takt time. The amount of processing cycle 9/04 --
Read MoreCycle 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.

This model, based on the mechanics of the plastic deformation of metals in the cutting zone, covers the main factors that affect the cutting forces. This model provides the basis for a model of the margin actually removed, which permits calculation of the number of passes and the cycle time with specified cutting conditions, when the
Read MorePerformance = (Ideal Cycle Time × Total Count) / Run Time. Ideal Cycle Time is the fastest cycle time that your process can achieve in optimal circumstances. Therefore, when it is multiplied by Total Count the result is Net Run Time (the fastest possible time to manufacture the parts). Since rate is the reciprocal of time, Performance can also be calculated as:
