The emergence of new manufacturing technologies means that production costs will need to be reduced constantly, in order to generate greater market competitiveness. The use of auxiliary programs for the cutting of sheet metal is therefore becoming increasingly necessary. This article´s objective is to compare the automatic arrangement and the manual arrangement in a grouping software, comparing the manufacturing costs with and without optimization. For comparison purposes, the components of a pre-cleaning agricultural machine were used, using steel plates (AISI 1020) of seven different thicknesses. For the price analysis, the arithmetic mean of the value acquired in quotations from three different suppliers of raw material. After the data were checked by the production team, the drawings were submitted to processing by ProNest 8® software (Hypertherm), where cutting parameters were established according to the machine manufacturer's manual, the parts were adjusted through the automatic nesting mode and the manual plot mode, the results for both methods were obtained directly from the sheet utilization report from the software. In the 1.2 mm thickness metallic sheet, any difference was observed in the cost of the techniques. In the 1.5 mm, 1.9 mm, 2.65 mm, 3.35 mm, 4.75 mm and 6.35 mm thick sheets, differences were found, accounting for about 23% reduction in production costs. |
