Increased Production: 315 pcs/shift
Scrap reduced: 715 pcs/month
Total Savings: $4000/ month
Part: Internal sprocket with three flanges.
Operation: Machine flanges.
Tolerances: .170mm runout between the flange faces and the ID.
Production Requirements: 15,000/Month
Part Issues: .001mm of misloading (from machine automation) results in .0025mm of runout. Tried: Original method was to use a 3 Jaw chuck, relying on machine automation to load the part square against the workstop.
Recommendation: Switch to Positrol Drawdown Chuck that centers and pulls back to eliminate dependancy on machine automation.
