Abstract:
Estimating quantities in machining processes is a complicated and valuable task, since there are many parameters involved during the processes. A low-code programming tool was developed in PowerApps called Manufacturing Time Tool (MTT) to estimate manufacturing time in machining processes such as conventional turning, vertical turning, CNC turning, milling, boring and sawing. The tool uses theoretical and empirical parameters, with the empirical parameters collected in the field and the theoretical ones obtained from specific literature in the area. After 5 months of using the application, 337 samples of estimated manufacturing times were collected and compared with actual manufacturing times. The analysis was carried out using Excel, where the application's hit ratio was calculated and transformed into a percentage for each process. The results showed an average hit ratio of 96% for the sawing process, 90% for the turning process, 90% for the milling process and 91% for the boring process, demonstrating the effectiveness of the tool. The study highlights the importance of production planning, programming (PPC) and control in machining, emphasizing the importance of PPC tools in meeting customer demands and increasing the efficiency of manufacturing processes.
