CAM (Computer Aided Manufacturing) software, one of important aid means of numerical control machining, improves the automatic level of processing with its application in numerical control machining industry. According to the character of woodworking curved jaw (WCJ), limitations of secondary development with existing CAM software were analyzed, and the advantages and basic principles of CAM which was independent development were introduced. In this CAM, dxf files as graphic information input for WCJ. Finally, CAM for WCJ was developed with VC++ and OpenGL.

This paper reports a novel method to generate adaptive spiral tool path for the CNC machining of complex sculptured surface represented in the form of cloud of points without the need for surface fitting. The algorithm initially uses uniform 2 D circular mesh-grid to compute the cutter location (CL) points by applying the tool inverse offset method (IOM). These CL points are refined adaptively till the surface form errors converge below the prescribed tolerance limits in both circumferential and radial directions. They are further refined to eliminate the redundancy in machining and generate optimum region wise tool path to minimize the tool lifts. The NC part programs generated by our algorithm were widely tested for different case studies using the commercial CNC simulator as well as by the actual machining trial. Finally, a comparative study was done between our developed system and the commercial CAM software. The results showed that our system is more efficient and robust in terms of the obtained surface quality, productivity, and memory requirement.

With the development of scroll technology, the requirements of more efficient and more accurate processing method for scroll compressor parts become more urgent. This paper proposes a method to improve the machining effect of scroll compressor. The approach is based on 3-point arc approximation method which divides combined profile of scroll wrap into subparagraph arcs that can be interpolated on CNC System. This approach simplifies the programming process and improves the curve fitting effect. The results indicate that the fitting error is in the predetermined range, and the interpolation points of cutter center track are significantly less than those based on CAD/CAM software. The method presented in this paper is of significance to the NC machining of novel precise scroll profile.

The impeller blades are hard to machine for its complex and curved surface structures. It is almost impossible to manufacture the blades by manual programming on Numerical Control Tool. Now, the program almost is completed by the three-dimensional CAD/ CAM software, such as UG, Pro/Engineer, CimatronE which have a lot of machining strategies suitable for a wide variety of parts. However, the result is not perfect if you choose improper strategies. Even more, machining marks will be left on the parts’ surface. This paper takes the impeller for an example and gives the solutions for eliminating machining marks left on the impeller blades’ surface through a comparative analysis on the 3-axis finish machining strategies in CimatronE.
