Aug 03, 2021· Finally, calculate the cycle time. Using the formula we find the cycle time to be 1000/480 = 2.083 min/part. FAQ. What is cycle time? A cycle time is a measure of how long it takes to produce a given part. For example, a part may take 20min to run 10 parts. The cycle time is then described as 2 min per part.

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:

Face grinding cycle time is a function of robot system time constant and grinding process parameters. •. Robot compliance increases the face grinding cycle time and the system time constant. •. For given robot stiffness and wheel hardness, cycle time decreases with increasing wheel speed and infeed rate. •.
