Abstract
One of the main solutions for reducing NC tool-setting time is based on the use of tool measuring machines (TMM). However, when the tool data are available, a number of issues still remain as to how to transmit the data to the NC tool-data register. The tool information is usually sent to the NC machine on printed labels, resulting in inadequate integration in the manufacturing system. In addition, there is no standard format for storing the tool-setting data in the NC memory, resulting in a wide variety of tool data formats. While it is possible to find commercial solutions for integrating TMM to a large number of NC systems, such solutions require a large postprocessor database. Furthermore, the solutions provided by TMM developers are proprietary, making it difficult to integrate these to other upstream and downstream systems. The main purpose of this work is to propose a methodology to promote this integration on the shop-floor using an open format. This study is based on a review of the related literature and on a survey carried out in 27 metalworking companies. The implementation details of a system for integrating tool-setting data—data integration for tool setting (DITS)—and the successful results of tests carried out on a shop-floor are presented and discussed in this paper.
