Creation of Curved Surface by Lathe Turning -Development of CAM system using original tool layout-

The machining of 3D curved surfaces with an un-axisymmetric axis by lathe turning is proposed considering the best machinable tool layout. The best offset tool layout from the central axis of a spindle enables us to machine curved surfaces and to obtain a long tool life for hard material workpieces using a rotary tool. A dedicated NC program for the 3D surface using the original CAM system has been developed and applied to what. The machining results and the validity of our system are evaluated in this paper.

Development of CAM System Based on Simulation of the Copy Operation - An Application to the Boundary Representation Method and High Efficiency Machining -

A CAM system, based on a simulation of the servo data generation method of a copy milling machine, was developed. In this system, the tool path data can be calculated directly using the coordinates of the contact point between the defined shape and an imaginary stylus, without the preceding processes of generating an offset surface and checking the tool interference. For application of this algorithm to a model which is expressed using the boundary representation method, the algorithm was modified slightly. Since the contact point is regarded as the point nearest to the center of the imaginary stylus, which is on the model surface, all the intervals between the center of the imaginary stylus and the constructing surfaces which are close to it are calculated. The point which has the shortest interval is the nearest representative point of the model data and the contact point, in the case in which the interval is equal to the radius of the tool. A rough tool path, which is composed of an imaginary block and a spiral finishing tool path, which enables tools to feed with smooth cutting has been developed using this algorithm. Toolpath simulations and cutting tests show that the CAM system developed was able to generate appropriate CL data with high accuracy and reliability.
