Once OP3 completed its task, part will be transferred manually for threading process on OP4. OP4/1 is a Fanuc Robodrill
machine while OP4/2 is using KIRA VTC 309. The requirement for two separate machines to carry out this process is
because of the long machining time of this process. Whenever the processes accumulate too much work-in-progress (WIP),loader on existing OP3 which is equipped with a sensor shall automatically stop machine OP1, OP2 and OP3. The operator
shall need to wait to unload parts onto these machines.
