Arc of contact and average chip thickness are essential for optimizing rough-machining operations. In todays' competitive manufacturing environment, shop managers are constantly looking for process improvements that will help them reduce costs and save time. More and more shops are turning to advanced machining strategies to reduce machining cycles, especially during roughing stages. Unconventional strategies like high-feed milling, trochoidal milling and dynamic milling have grown in popularity as manufacturers strive to reduce the costs associated with the often-expensive process of preparing individual parts for final machining. These CAM-based rough-machining strategies are centered on a cutting tool's arc of contact and average chip load. By manipulating the tool's arc of contact through its CAM-generated tool path, shops can boost roughing speeds, effectively control process temperature and apply higher feeds per tooth. Additionally, many shops have found that they can also increase depths of cut to significantly shorten overall machining cycle times - all without placing any additional strain on machine tool spindles.
