ESTIMATION OF HARD PLAIN RUBBER ROLL MANUFACTURING PROCESS TIME USING LINEAR REGRESSION METHOD

Competition in the industrial world today requires producers to compete in providing good quality products with short production times and relatively low production costs. This relates to production machines which have an important role to produce products with good quality. PT. Voith Paper Rolls Indonesia is a service and manufacturing company engaged in roll repair and manufacture of roll cover materials. One of the production processes carried out during roll repair is the turning process which is carried out twice. In the turning process, there is often a significant time difference between the actual time and the estimated time obtained from the existing formulation. Therefore, this report will focus on efforts to improve the calculation formulation for the estimation of turning process time on lathe A on hard plain rubber roll by analyzing the effect of surface area on processing time using a simple linear regression method through the IBM SPSS application.
