In machining screws which are important members in mono pumps or progressive cavity pumps, CNC turning center with 3 axes is usually used. This soil of screw machining requires large amount of CL data points and rotational tools are used in machining. When working out the CL data points, consideration of possible tool interference is important in order to avoid undercut. This paper describes the checking methods of tool interference that could occur in the screw machining on the CNC turning center. First of all a specific shape of a screw cross-section that could commonly be applied to all screws was chosen, and then possible tool interference associated with that shape was identified. Checking method was mathematically developed and verified. This checking method will be utilized in the CAM system developed by the authors for screw machining on the 3-axis CNC turning center.
