Automation: Deciphering the many types of NC program optimization

Chicago, Illinois – Every CAM vendor, machine tool builder, and cutting tool supplier promotes the importance of cutting optimization. But what is really meant by optimization? This presentation will provide an analytic overview of the different types, with special focus on which optimization techniques are best suited for different materials or machining processes. It will also introduce attendees to a new physics-based optimization method that determines the maximum reliable feed rate for a given cutting condition based on the following four factors: force on the cutter, spindle power, maximum chip thickness, and maximum allowable feed rate.

Key points:

• Define several types of optimization software, and verify the value of optimizing NC program feed rates
• Identify multiple methods for optimizing NC program feed rates
• Explore automated ways to simplify the process of optimizing NC program feed rates
• Show how to calculate ideal feed rates by analyzing chip thickness and cutting forces on the tool
