A MACHINING SUCCESS STORY

One of the reasons that we teach all employees the concept of Theory of Constraints is because of the success rate it has of solving problems. A recent use of the concept in the Machining Department is another example of the way it works for us.

IDENTIFY

Problem: Production on the CNC Lathes was not at optimum cycles per shift and needed to be increased approximately 14%.

EXPLOIT

Causes: Some of the causes were identified as gauging and inspection time, material handling, machine cycle time, running scrap parts, maintaining the machine, etc.

Investigate possible Cures: reorganize the work station, review the program, keep staging area full, making the maintenance faster, improve gauging time, etc.

Actions Required: Chart performance of the CNC lathes, add wheels to the chip barrel, employee assigned to clean the machine each week, 5S the area, etc.

Improvement: The CNC lathes are now producing 18.5%! more cycles per shift.
