Abstract :

 On the shop–floor of small and medium make–to–order companies, NC machining start–up still remains highly dependent on humans. There are essentially two tasks that have to be carried out before machining starts: the first is to set up the workpiece on the machine table, and the second to set up the cutting tools. When these are done manually, a significant amount of time is required for the machine operator to intervene and the flexibility and productivity of the process is adversely affected. Tool offset is important in high–precision machining, as the tool–origin can become changed by the tool replacement. The required relationship between the NC machine origins (references) can only be determined after the workpiece and tool settings have been completed. In particular, the tool setting task can be highly time consuming when small batches of complex parts are involved, mainly because frequent tool–set changes at the NC machine are required. In this project, a new design of tool holder is suggested for a 2–axis turning center (LMW LL20T L5) and thereby it minimizes the tool setting time for all the turning tools used in the machine. The main purpose of this work is to propose a design of tool holder where presetting of the tool is done quickly and accurately compared to the conventional method and the manual procedure of tool offset measurement can be eliminated. As the job is being changed frequently, Z–offset is not considered and only the X–offset has been taken into account for compensation. A methodology for the design of tool holder is made and analysed. Implementation details and the results of tests carried out on the machine are presented and discussed.
