Calculation of cycle times

There are four methods of estimating the time to perform a task by a robotic system: simple, intermediate, most exact and parts tree. All are based on the fact that robot performance is predictable and repeatable, and that when the dynamics and control algorithms of a particular robot are known, it is a straightforward procedure to calculate assembly times.

Cycle Time Estimating

Apr 28, 2015Cycle Time Estimating. You have to know how many square inches per hour you can cut with the size wire you are using (also dependent on the thickness of your work piece), divided into the number of square inches on the job to come up with a number of hours (or minutes) required to do the job. If you take a rough and several skims,

How to Measure Cycle Times

Oct 06, 2015Most definitions for cycle time I have found online are rather basic, defining cycle time often as the time required to complete a cycle (Merriam Webster). However, for practical terms, this definition is way to broad. A much more useful definition for me is: The cycle time is the fastest repeatable time in which you can produce one part.

Adapting takt time to the job shop

Jul 11, 2019Accounting for breaks, the average 8-hour shift has 450 minutes available. To calculate takt time, divide 450 units by 100 minutes. This results in a takt time of 4.5 minutes per unit. To determine the correct number of operators, divide the total cycle time (8 minutes) by the takt (4.5 minutes). The result is 1.78, representing 1.78 operators required.
