Performance is how the equipment is performing against its capacity. In this calculation, we use the ideal cycle time and operating time to determine how many parts the machine can produce under ideal operating conditions. We then calculate the ratio of how many parts we actually produced versus the capacity. Capacity Formula:
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 force in the first spark-out pass, a calculating method of the real ground depth in continuous pass process is proposed. And, this method is experimentally evaluated.
Oct 24, 2018· 2. Continuous dressing, which is beneficial in large-quantity production in materials that are difficult to machine or grind.The continuous dressing enables the grinding wheel to stay sharp constantly, while maintaining intricate forms. Continuous-dress creep-feed grinding uses an overhead diamond dressing roll to plunge dress continuously during the grinding cycle.

OEE can also be calculated using the simple calculation. Formula: ( Good Count × Ideal Cycle Time) / Planned Production Time. Example: (18,848 widgets × 1.0 seconds) / (420 minutes × 60 seconds) = 0.7479 (74.79%) The result is the same in both cases. The OEE for this shift is 74.79%.
How to Calculate Cycle Time. In short, cycle time is the total elapsed time you need to move a task from the moment it enters the "in progress" (working) stage to the moment it is considered finished. So the simplest way to measure the cycle time of an assignment is to count the number of days it spends being worked on.

Mar 01, 2011· The calculator is developed in Microsoft Excel and available in inch and metric units. Table 1 shows its computational worksheet (inch units) before the required values for computation of the cutting time are entered. Table 2 shows the calculator after process parameter values have been entered and cutting time calculated.
Balance and run-out of the grinding wheel are mechanical properties that must be addressed at the time of each grinding wheel mounting. Regardless of the overall rigidity of the machine, surface finish and grinding performance will not be maximized if the grinding wheel is not running true and is not dynamically balanced.
It can be seen from Figure 8 that the cycle time decreased very quickly with infeedrate with k = 1. The cycle time for the first workpiece took an unusually long time of 74 seconds probably due to this being the first workpiece to be ground after changing the grinding wheel. CBN wheels often have a poor grinding efficiency just after dressing.
Cycle Time example (+ Cycle Time Calculator in Excel) Let's take the doll factory example once again, and look at the Cycle Time for Doll# 1 (Jessica). We'll take the same Net Production Time, and assume that 45 dolls are really made during this time: Net Production Time = 550 minutes.
