The goal of "Clean Manufacturing" (CM) is to eliminate waste, aiming at zero waste, by integrating environmental best practices into the manufacturing process. CM is a continuous preventive strategy, which concentrates on resources and manufacturing processes to eliminate waste. One of the biggest benefits to companies is that CM reduces operating costs, especially in the areas of chemical management, wasted raw materials, waste collection and treatment, and pollution control. CM increases the efficiency of the manufacturing process and the productivity of the company. It provides opportunities to reduce regulatory obligations, risks, and costs. The idea of implementing CM could be suggested or encouraged by internal or external sources. Finally, there's the driving force behind much of what a manufacturer does - the client requests it! The main goal of the project was the reduction of chip sticking in the inner part of a machine tool. New coatings and surface modifications have been applied. With standard coatings (modified DLC) as well as new coatings based on nanoscale metallic fluoride powders - the amount of sticked chips at the sheet metal surface after machining of steel and aluminum alloy was reduced up to 45percent. The machining results are compared with laboratory tests and also with the measurement of surface energy of the coatings in relation to four selected lubricants.
