Now, CNC Software is working on a revision of the software that will allow this shop and other customers to fully automate programming of this variety of plunge roughing as well.Įven so, the 15 or 20 minutes of extra programming time currently required for a given roughing job is easily justified by the potential payoff. Its developer, CNC Software, Inc., of Tolland, Connecticut, was quick to see the value of the technique Hilton Tool had developed. The software he prefers-Mastercam-may soon be updated to make the extra programming work unnecessary. Thus, his custom technique adds to programming time.

He applies the software’s functionality in combination with some of his own manipulation. Vandewalker’s own internally developed process requires. This feature automates programming of the standard, more widely used version of the technique, but it doesn’t automatically generate exactly the tool paths Mr. Vandewalker obtains these using CAM software that offers plunge roughing functionality.

The work of this dissertation will aid in developing the next generation of CAPP tools and result in lower cost and more accurately machined components.This different style of plunge rougher calls for a different pattern of plunge roughing tool paths. The algorithms developed here facilitate transfer of complete surface geometry information from CAD to slice models. The conversion from CAD to slice model results in the loss of model surface information, the consequence of which could be suboptimal or incorrect process planning. The third research problem addresses challenges with geometric singularities that can occur when 2D slice models are used in process planning. These algorithms allow the rapid machining of a wide variety of parts with higher geometric accuracy by enabling access to visible surfaces through the choice of appropriate machine tool configurations (i.e. This problem specifically considers a generic 3-axis CNC machining process for which CAPP algorithms are developed. The second research problem is related to a new method for discrete multi-axis CNC machining of part models using feature free polygonal CAD models.

The CAPP algorithms developed for this problem ensure the complete rapid machining of multi surface parts by providing better setup orientations to machine each surface. These types of parts typically have different requirements for each surface, for example, surface finish, accuracy, or functionality. The first research problem involves a new method for the rapid machining of Multi-Surface Parts. It specifically focuses on 3 challenging problems in the area of multi-axis CNC machining process using feature free polygonal CAD models. This dissertation provides new methods for the general area of Computer Aided Process Planning, often referred to as CAPP.
