On the determination of the maximum turnable state of a part

摘要

Machining planning is an important task and requires experienced personnel and directly affects the cost of a product. Computer aided methods are increasingly being developed and used to assist in the planning task. We describe a new concept, the Maximum Turnable State of a part, and algorithms for its computation. The concept is intuitive and relates to an intermediate state of every turned part. By recognizing it explicitly, and using it in the machining planning, efficiency can be increased. We describe the concept, its use, algorithms for its determination and some examples.
