Sažetak
Given the significance of manufacturing cost estimation, the present study is focused on the analysis of total and specific manufacturing costs in medium longitudinal turning of C45E steel using coated carbide inserts under optimized cutting conditions. To this aim, a single-objective optimization model with process constraints, related to available cutting power and favourable chip slenderness ratio, was developed and solved using a generalized reduced gradient algorithm. In the proposed optimization model, a dimensional analysis-based model for cutting force prediction was developed and used for the estimation of the cutting power, while the Taylor model was used for estimating the tool life. In order to analyse total and specific manufacturing costs under optimized cutting conditions, four machining operations with different volumes of material to be removed, performed using lathes with different available cutting power and two alternative coated carbide inserts were considered. In addition, an analysis of the share of cutting insert cost and labour and overhead cost, as well as their ratios, under optimized cutting conditions for both cutting inserts and lathes and different volumes of material to be removed was performed.
