Through the cutting operations of the different metallic materials, large cutting forces are developed, they depend on the material to be processed and on the cutting parameters. During the cutting operation, due to the friction between the tool and the material to be processed, an important amount of heat is released. As the friction between the elements is higher, the heat generated by the attachment can disturb the cutting process. If the temperature from the cutting process is higher than a certain value, the resulting surfaces may have a number of processing defects. In order to reduce the temperature value of the cutting process, different cooling systems have been developed over time that use a wide range of cooling liquids. Cooling liquids have a number of advantages and disadvantages, after the cutting process they have to be discharged and their negative influence on the environment to be minimal. Recent studies have attempted to reduce this amount of coolant by streamlining fluid flows. Systems that use minimal amount of lubricant or coolant are MQL (Minimum Quantity Lubrication) type. These systems have special nozzles so as to obtain the best possible distribution of the coolant in the cutting area, as well as a good mixing if different cooling liquids are used. This paper aims to study the cooling systems for the cutting processes, forms of nozzles to send the fluid in the working area, thereby thermal analysis, from the desire to use an efficient MQL system.

In practice, different cutting processes are encountered, each process having different characteristics. Due to the existing friction forces between the workpiece and the cutting tool, a significant amount of heat is generated. This amount of heat can be determined by experimental measurements. This paper aims to study the way in which the temperature is propagated in the workpiece, so that the phenomenon can be understood and determined how this excessive heat can be removed from the cutting area.

The paper treats the analysis of losses of juice/material resulting from shredding of food materials with soft texture by means of metal wire cutting. For a better relevance of determinations have been chosen different food materials, different diameters of metal wire cutting and different heating temperatures. The objective of this analysis is to identify the correlations that exist between the cutting device and the product obtained after shredding, in order to improve shredding efficiency by reducing the losses of juice / materials resulted from shredding of food materials.
