Abstract
Computer numerical control (CNC) technology has received high level of investment around the world. Considering machine tool for machining operations, almost one third of those installed in Brazilian industrial companies is composed of CNC machines. About 46% of them are less than ten years old and belong to a generation of machine tools that should have a higher density of automation, incorporating features and advanced production techniques that suppose efficient management. However, there is a low rate of utilisation of available resources, such as tool presetting, in-process measurement systems and automatic load and unload to reduce idle time. Additionally, there is a reduced use of techniques to achieve higher maximum cutting speeds and longer tool life. There is also a low rate of use of low environmental-impact techniques such as dry machining, and a very low percentage of companies that treat and reuse cutting oil.
