Build-Up an Economical Tool for Machining Operations Cost Estimation

Currently, there is a lack of affordable and simple tools for the estimation these costs, especially machining operations. This particularly true manufacturing SMEs, in which cost machined parts usually performed based only on required material part production, or involves time-consuming, non-standardized technical analysis. Therefore, tool was developed, calculated times amount material, final drawing requested workpiece. The developed primarily milling machines, considering milling, drilling, boring/threading Regarding considered materials, were aluminum alloys. However, some polymer materials also considered. first estimates time total production then calculates cost. estimated operations, as well drawing, programming, machine setup time. A complexity level introduced, number details operations each workpiece, will inflate times. tested company setting, comparing operation values with real ones, wide variety differing complexity. An average error 14% registered, quite satisfactory, this most impactful terms are still problems regarding accuracy estimating finishing
