Design of a High Accuracy 3-Axis Coordinate Measuring Machine Working on the Shop Floor

Article Preview

Abstract:

One of the key features of advanced manufacturing technologies is the metrology of geometric quantities. Coordinate measuring machines (CMMs) now are widely used to perform relevant measurements. Normally, the use of CMMs in traditional quality control rooms, isolated from the production floor, often proves unsuitable for effective and timely feedback on the manufacturing process. However, CMMs are sensitive to environmental factors such as humidity, suspended dust and oil, vibrations, and especially temperature. For this reason, measuring machines must to be designed with features that make them more resistant to the environmental influences on shop floor operations. The main goal of this work is to enhance accuracy of a CMM working on the shop floor conditions by design improvements and error compensation. A 3-axis CMM will be built with some improved designed features and a software compensation technique will be applied to enhance the machine accuracy.
