6. SPEED LOSS

These are losses that occur because the equipment speed is slow. They can be defined as follows:
• Losses due to a difference between the design speed (or standard speed for the item concerned) and the actual speed
• Losses caused when the design speed is lower than present technological standards or the desirable condition

As an example of the first type of losses, if the standard cycle time is set at 40 seconds, and the actual operation time is 50 seconds, the speed loss is 10 seconds.
As an example of the second type of losses, if the set cycle time is 60 seconds, but it could be shortened to 50 seconds based on current-level improvements, the speed loss is 10 seconds.

Reasons for speed loss

-We mistakenly believe that the current machine cycle time is normal.
-We must slow down the machine cycle time to avoid problems.
-The equipment was poorly designed .





Reduction of Speed Loss

– Capacity balance of each process
– Actual cycle time measurement
– Reduction of cycle time
– Problem analysis for cycle time w.r.t. part quality.
