Abstract
Abstract: This paper deals with the Quality Circle Case study carried out at Tecumseh Product Company Compressor Manufacturing Division. The company has been sending Kit Assembly to their customer Tupelo. The customer assembles stator on Kit by tightening the 4 bolts with the help of Nut runner and some of the bolts were broken while assembling at customer end. The kit is rejected as a tapping defect and cost is debited to supplier plant. It was observed that the customer end PPM which was more than the target from AW Kit Assembly line. Victory Tecumseh quality circle working in this area took up this problem for study. A systematic application of quality control tools was used to find out the solution for the problem identified. The problem was analyzed and found the root causes as spring loaded tap adaptor travel incomplete depth and Chips getting trapped in stator holes due to Manual air jet cleaning of stator holes. Manual air cleaning of stator hole chips leading to missing & solidification of chips in the tapping holes. Based on the analysis the team suggested different solutions and develop a fixture to remove Chips from crank case fixing holes and providing sensor at machine spindles the problem could be overcome. Based on the suggested Developing solutions for the Root Causes the team adopted a concept of feeding air jet into crank case blind hole 3/4 depth and blow high pressure air through convergent nozzle by which the scrap blows out from the gap around jet. The suggested Solution has been implemented and the tangible and in tangible benefits have been encouraging.
Keywords- Customer end PPM, Kit, Quality Circle, Quality Control tools
