Squared Corner Shaping by 6-Axis Control

This paper describes a new machining concept in the squared corner shaping, making use of the cutting characteristics of non-rotational cutting tools and 6-axis control. Though the 5-axis control machining with conventional rotational tools makes it possible to machine sculptured surfaces efficiently and accurately, some problems still exist in the machining. For example, it is impossible to mill workpieces without round corner. This is due to the usage of rotational tools. The 6-axis control machining with a non-rotational tool allows a variety of machining possibilities. In the study, a new 6-axis CAM system for squared corner shaping was developed to remove the remaining of corner radius after rough cutting with rotational tools. The validity of the system is experimentally confirmed.
