The design, modeling and simulation are one of the key technologies of CAD/CAM software system. The mathematical model of the CAD/CAM system for machining spatial surface was given firstly. After the design idea of the CAD/CAM system was describe in detail, the workflow of the CAD/CAM software system was illustrated, and then data exchange mechanism was determined and detailed steps were given simultaneously. Under MFC framework, the CAD/CAM software system was finished using OpenGL, and the configuration and machining process simulation were carried out. All these works provide an effective approach to raising the productivity and precision of machining spatial curve surface part by WEDM-HS.

This paper describes the process of integrating engineering design, manufacturing, and production in the area of manufacturing automation. The work was done within the scope of a Mechanical Engineering senior course that’s objective was to introduce students to the processes of advanced manufacturing and to solving practical engineering problems in manufacturing automation. The students’ efforts at integration covered automation of conceptual and geometric designs, automation of machining process, and machine sequence optimization. The CAD/CAM software, CAMM3 Micromodeler, G-code, NX8, Solid Works, DELMIA/QUEST, and Mastercam were used successfully in a sequence. A survey of the students’ opinions about the effectiveness and user friendliness of the software was summarized at the end of the semester. The elements of the course were integrated in the Final Project. Full automation of integrated design and manufacturing data exchange were found to be too difficult to accomplish. However, the use of the automation software in a sequence, together with data export and import, marks a significant step forward towards integrated manufacturing automation. The research to accomplish this will continue and the results will be applied in order to reinforce the teaching and practice of Manufacturing Automation.

A novel computer-aided manufacturing (CAM) software system is proposed for laser ablation machining process. The algorithms and prototype software system is designed to offer efficient optimization of tool path for controlled delivery of laser energy into work-piece. The software simplifies part program creation and maintains constant velocity of the sample stage for each segment of a complex tool trajectory. These features enable efficient deposition of laser energy into the work piece and therefore, reduction in heat-affected zone is expected in laser ablation based micromachining. The reported software provides fast modification of tool path, automatic and efficient sequencing of path elements in a complicated tool trajectory, location of reference point and automatic fixing of geometrical errors in imported drawing exchange files (DXF) or DWG format files.

The Manufacturing Automation course in a standard engineering education prepares students for the most contemporary production and technology challenges. This paper describes Rapid Prototyping and Modeling done as subtractive and additive manufacturing operations in the scope of the UConn Engineering program, as well as its integration into the Manufacturing Automation course. It is a companion paper with IMECE 2014-38355 [1] that reports how students of Manufacturing Automation are exposed to rapid prototyping. This is done in the UConn School of Engineering Machine Shop, Mechanical Engineering Machine Shop and Laboratory of the desk top modelers. Some experience students gain also in MEM Prototyping Laboratory and during class trips to Pratt & Whitney/ UConn Additive Manufacturing Research Laboratory and to CNC Software Inc Experimental Testing Shop. One of the objectives of the course is to introduce students to the processes of advanced Subtractive and Additive Manufacturing (SM and AM). The CAD/CAM cutting software such as CAMM-3 Micromodeler, G-code and Mastercam were used successfully in those operations. The elements of CAD/CAM software were integrated in the model cutting exercises. Full automation of integrated design and manufacturing data exchange was attempted but was found still not possible to accomplish. However the use of automation software in a sequence, tin tandem with data export and import, marks a significant step forward towards integrated manufacturing automation. The research to accomplish the next level of automation will be continued and the results will be applied to reinforce the teaching and practice of Manufacturing Automation. Significant role in helping students to understand the methods of subtractive and additive manufacturing has cooperation with two Connecticut companies that achieved outstanding results in modeling and prototyping. These are Pratt & Whitney in East Hartford and CNC Software Inc in Tolland, Connecticut. The class visits to their facilities and experience with their equipment played a significant role in understanding of the subtractive and additive machining processes. Efforts to introduce students to the concepts of subtractive and additive machining process are described. Conclusions about the teaching methods of product machining concepts and lessons learned are pointed out.

Abstract This paper presents the machining process of the complex copper electrodes. Machining of the complex shapes in copper is difficult because this material is soft and sticky. This research presents the main steps for processing those copper electrodes at a high dimensional accuracy and a good surface quality. Special tooling solutions are required for this machining process and optimal process parameters have been found for the accurate CNC equipment, using smart CAD/CAM software.

With the help of IGES standard file which was the exchange specification of initial graphics, different CAD system could change the data of product by neutral file’s format conversing. The automatic generation of 3D-Model curve surface in the MCNP input file was realized by using VC++ language.This method has solved the problem of the complication of MCNP geometric modeling process and the 3D-Model input problem in the MCNP. The input of MCNP was transferred the application problem of CAD/CAM software. The data and figure of varies software could be shared and converted. The work of design could be simple, the process of design could be speeded up and the cycle of design was shorted. Work efficiency and practicability were improved. If precision was controlled in 3D-Model, the result could be expected by contrast.

In order to meet the needs of enterprises for chamfering complex parts, based on the customization of commercial CAD/CAM software, chamfer programming software is developed. According to user’s machining demands for a part, a chain of edges of a part is extracted from its 3D model. With preprocessing of the chain of edges, the continuity of the chain is estimated, and the start and end point of those edges are automatic obtained. Furthermore, with human-machine dialogue, machining parameters is set by users. By definition of the primary and secondary surfaces of the chain of edges, and interpolation of the edges, the positions of cutter location point and postures of cutter are calculated. Finally the interference of tool path is checked, and tool path is simulated. The software solves the programming problem of chamfering complex parts.

Combining the machining process simulation on UG NX software and the mathematically analysis, a new solving method for the tooth crest curve equation of spiral bevel gears is proposed in this paper. The steps are as follows:1) Establishing the gear blank cone equation in the original coordinate system; 2) Finding the gear convex and concave profile equations in the new coordinate system; 3) Integrating the original coordinate system and the new one through geometric transformation and then deducing the tooth crest curve equations on both sides. The equations will help calculate the cutter’s position and pose in addendum chamfering process, with the chamfer automation achieved.
