Abstract:

The article presents research and analysis of the results obtained for various wide-slot strategies and the impact of using these strategies on the economics of production. The article determines the impact of changing machining parameters on cutting forces. Three strategies for making wide grooves were tested - trochoidal, plunge, and dynamic. Measurements were carried out for various machining parameters, selected according to the manufacturer's recommendations, taking into account the selected workpiece material and cutting tool. The evaluation of the cutting forces in the slotting strategies tested showed that machining should take place in the direction of the tool holder, which reduces the cutting forces by about 10%. The use of the trochoidal method of making grooves gives significantly lower cutting forces compared to other methods. The plunge grooving method produces the highest cutting force components, which has a direct impact on tool life. To calculate tool costs, a computer program was used, in which manufacturing costs were compared. The calculations were carried out depending on the feed value and variable cutting speed values and the strategy used to make wide grooves.
