1. 3 CASE STUDY ON BMW Z-4 - CHANDAN NAGARAJA 1RVO8ME021

3. As volume increases we must have some strategy in production method so as to reduce high cost and manufacture lead time. This give rise to use of AUTOMATION PROCESS.

6. In BMW Z4 car engine main part are temporarily stored (buffer storage) in Munich, German plant until Crank case of engine is manufactured and arrived from Landshut (German).

7. In Spartanburg country, USA car parts like windows, steering, chassis all are separately manufactured and stored in buffer storage until Engine unit arrives from Landshut (German).Work-Station 2 Work-Station 1 Buffer between work stations

8. Engine buffer storage Car Body part buffer storage

9. WORK PART TRANSPORT Asynchronous Transport Method ; This is a method in which work part is loaded at work cells while the conveyor system waits till the operation is completed at each work cell. The conveyor moves to the next cell, only after completion of operation time requirements at each work cell. This method is flexible & suited, so it is used in BMW Z4 Engine transfer line in Spartanburg plant. Its used to assembly body operation of car and also in paint shop.

11. WORKPART MECHANISM In Spartanburg plant special type of workpart mechanism is used which is combination of linear and rotary mechanism BMW call it as “Tilt and Wear” Work part is conveyed from one station to the other and also used to index at equal angular positions according to requirement along 360 degree. It is used assembly of Car parts so workers will have ease of access to all parts of car. It also have Automated Walking Beam Transfer System and Belt Drive Conveyer mechanism in transfer line of car.
