This paper investigates the application of the high-pressure jet assistance (HPJA) in rough turning of Inconel 718 with coated carbide tools. The region of operability, which sets the boundaries of the process parameters, has been experimentally determined using the tool-material pair (TMP) methodology. The assessment of HPJA machining performance is based on response surface methodology (RSM), which integrates a design of experiment (DOE) and a regression modelling technique for fitting a model to experimental.

The increasing demands of the industry and cultural sculpturing for complex shaped products in natural stone makes the use of flexible and completely automatic machines such as CNC machining centers necessary. These machines mainly use diamond tools such as synthesized diamond mills, circular blades, polishing tools, etc. For the machining of stone, diamond tools are becoming increasingly important and suitable, especially for the machining of granite and other hard stones.

An experimental study has been performed to investigate the capabilities of dry, conventional and high pressure jet assisted turning of two different hard-to-machine materials, namely hard-chromed and surface hardened Ck45 and Inconel 718. The capabilities of different hard turning procedures are compared by means of chip breakability, technological windows, cooling lubrication efficiency, and cutting forces. All machining experiments are performed under conventional cutting speeds using coated carbide tools.

The paper presents methods for achieving production sustainability on a machining technology level. In order to tackle the sustainability issues, the paper promotes sustainable production via the improvement of machining technologies that have a high potential to cut costs and improve competitiveness by reducing resource consumption and thus creating less waste. The idea is confirmed by a case study on the implementation and sustainability evaluation of innovative cryogenic and high pressure jet assisted machining processes in comparison to conventional machining process.
