This study aims to determine the replacement schedule of chisels (tools) that exist on a machine. Generally in the computerize numerical control machine installed several different types of cutting tool. If the chisel is replaced in long time, it will affect the low quality of the products, meanwhile when the chisel replaced often will increase replacement cost and the losses due to interruption of the machine frequently. In general, replacement models have been developed only consider the replacement cost of preventive and corrective replacement costs. At the phenomena occurring in the replacement chisel there are three costs to be considered in determining the replacement schedule that is a quality costs, preventive replacement costs and corrective replacement costs. Based on the model that’s developed by Jardin, in this research will develop the model considering the three of costs. The company where this study was conducted in Majalengka manufacturing company, PT. WIKA Industry and Construction. The output of the study is in the form of an optimization model to determine the replacement schedule tools in combination (group replacement), and the optimal schedule for the replacement of existing tools in the enterprise.
