Investigation of cutting parameters influence during milling process applying cold compressed air

Cutting fluids are necessary for implementation of metal machining process. They have a huge impact on the tool life cycle, reducing the temperature in the cutting zone, elimination of separated chips and improvement of the product quality. Using of cutting fluids results in increase of the production cost and in detrimental impact on the environment and human health. Due to the reduction of negative impacts and implementation of environmental laws, the industry is forced to reduce the use of coolants. Alternative types of cooling in combination with new materials for making tools and special coatings represent an appropriate replacement of the cutting fluid. In this paper the influence of cutting parameters (cutting speed vc, radial depth of cut ae, feed per tooth ft) on the surface roughness in the procedure of end milling along with dry machining, the use of emulsion cooling and compressed air cooling will be examined. Based on the change of input parameters, a decreasing and increasing trend of the surface roughness will be shown graphically.
