From the production process of steel structure cooling tower (Cooling Tower), version SPC-200 steel Department. Bookkeeper group has made a theoretical studies framework, related to the project. The cause of death in the steel Department. Which the Group selects the piece "in the lower arch is water tray" version SPC-200 study and analyzed for cause of death, from which the study found that there are several possible reasons why. And make a score ratings came out, making it apparent that is causing the problem. The following rating 1 is the standard to measure the curve because there is no equipment to measure the degrees of arc, and a rather specialized employees. Make the bottom piece curved shower tray has been staggering, it often causes of broken up (Rework) In this second section steps is not continuous because the bending piece is lifted from bending machine- Before the improvements, so the standard time before adjustment of Thai wooden rhythm instrument cycle. Welding, cutting and bending is equal to 35.42 seconds, 44.92 Seconds and 1254.1 seconds, respectively, and the bottom curve is given 3 rating plate water-induced distortions due to bending that would exceed the limit line degree curve. It causes of broken up (Rework), which improve the rank 1 and rank 2. 3.
.Therefore, When you know the reason that caused the problem, and the Group has to do is update already. It has made the display of updates in the lower arch is water tray. From the average of the resulting adjustment is equal to 77.8%, and the average loss after adjustment equal to 19.70% and from the adjustment makes it possible to reduce the time it takes to produce pieces of work in the process of bending pieces of work. By bending pieces of process standard time after updating to 705.40 seconds
