Investigating the Optimal Tool Path Strategies Based on Machining Time in CAD-CAM

One of the most significant issues that has drawn the attention of toolmakers is the strategies which lead to speedy production of tools and a faster way to meet the demands of market. Hence, toolmakers have made utmost effort to investigate the potential ways as to reduce machining time. One vital initial step in the process of production is roughening objects. CATIA and MASTER CAM are two of the softwares used in designing and producing NC CODE of tools. The two softwares are flexible in all the stages of production and are highly capable of producing product codes as well as displaying machining time. Numerous tools path strategies are incorporated in the aforementioned softwares. This article seeks to simulate tool-path planning strategies in accordance with the machining time displayed by the software. The accuracy of the operations verified the most suitable tools path strategy will be introduced in the present article. Research results indicate that the back and forth tools path strategy used in CATIA, and End Mill tools enjoy a minimum machining time. As well as that, when Bull Nose tools employed, the inward helical strategy consumes less machining time in comparison with the Master CAM.
