From that we have studied about Turning Process of Unfold spin board at M.A.P. Engineering
and Product Co., LTD. This company will product with customer order they not have the main line
production. They product about cutting, folding, turning and structural welding work. Our group has
going to study the process of unfold spin board production. We have studied since production process till
packing to prepare for customer. For this case study, we use another method for study Method Study and
Work Measurement. This method is studies orderly so we can bring the data from this study method to
analysis to find the efficiency of operation and can apply to improve the production process. The method
that we use for this case study include 1. Production Process Chart, it is used to record production process
so that make us understand the process easily. 2.Flow Process Chart is used to record step of flow process
so this recording make us can find number of operation and delay or free time obviously. We have seen
15 point of operation and 2 point of delay in this chart. 3.Left and Right Hand Chart, this chart is used to
record cutting steel 45 angle. According to this chart it shows us about operation and unemployment
obviously. In this cutting steel process have unemployment of left hand 15 point that is delay more than
14 point. So, when we have studied working process done. Next we have gathered the data to analysis
and figure out the efficiency for making us know the problem of work and can find the way to improve it
later. For improvement, we use principles of improvement that we have learned by this step first we use
Why-Why Chart to looking for the exact cause of problem and then this method show us that the problem
has cause from cutting angle and using the cutter machine. Later we have used principles of improvement
and design new method for reduce and adjust the problem. So, we have used 1. ECRS principles to
improve part of cutting work piece with Simplify principles by design Jig for holding work piece and use
check sheet to inspect the fault before send to other working part 2. Principles of motion economy we use
this principle to design working area by adding platform for set the machine suitable with staff. Also, we
have improved more working other part such as while staff is waiting for machine working they should
do some independence work concurrently, they should add the tools that use for assembly enough to
47
reduce waste time for waiting, they should have the table to put the work piece for reduce movement that
may make staff be tired, final they should have holder for measurement process that make them can cut
steel without measurement. For this case study that we have studied working process and suggested the
way to solve the problem with other method for Unfold spin board production will make the company
have production that efficiency extremely.
