Computer Integrated Manufacturing (CIM) is more » a small organization, reporting directly to the general manager, who has responsibility to coordinate the overall integration of computer aided systems at Bendix. In March 1982, a ninth division was added to the existing eight divisions at Bendix. In June, 1980, CAD-CAM Operations was formed to incorporate an integrated CAD-CAM capability into Bendix operations. Computer Aided Design (CAD) technology was introduced in 1976, when a number of 2D turnkey drafting stations were procured for printed wiring board (PWB) drawing definition and maintenance. « lessīendix Kansas City Division (BEKC) has been involved in Computer Aided Manufacturing (CAM) technology since the late 1950's when the numerical control (N/C) analysts installed computers to aid in N/C tape preparation for numerically controlled machines. The team made numerous recommendations that are detailed in the report. The functions of numerical control (NC), desi~ and process planning were separate and distinct. For all eornpanies visited except the small ~ work structure breakdown and responsibility were essentially the same as Y-12's at this time. This same strategy was evident at another of the companies but with more mobility of members. These teams consisted of the technical staff capable of completing the entire task and were xmintained throughout the project. In regard to organizational slructure and human resoukes, two companies were found to be using product or program teams.
#CAD CAM SYSTEM SOFTWARE#
It was apparent that these companies were trying to consolidate their software tools to reduce translation but had not been able to do so because no single solution had all the needed capabilities. All of the companies visited fOund the data exchange between CAD/CAM systems problematic. Most of the companies used Pm'Engineer for design to some degree, but found the PTC CAM product, PdManufacture lacking as compared to alternate CAM solutions. Because PrdEngineer is the de facto CAD standard fbr the NWC, the Benchmark Team targeted companies using Parametric Technology Corporation (PTC) software tools. The Inteznet was a technology that all companies were considering to either transport information more easily throughout the corporation or as a conduit for business, as the small firm was doing Successfully. The majority of companies were closer to identifying or using a single computer-aided design (CAD) system than a single computer-aided manufacturing (CAM) system.

The manufacturing computer tools were varie4 with most companies using more than one software product to generate machining data and none currently performing model-based manufacturing (MBM) ftom a common medel. In terms of engineering design software tools, the companies contacted were using both 3-D solid modeling and surfaced Wire-frame models.
#CAD CAM SYSTEM HOW TO#
There was evidence that many companies are trying to grasp how to manage current and legacy data. The results of this benchmark showed that all companies are moving in the direction of model-based engineering and manufacturing. The questionnaire was used throughout each of the visits as the basis for information gathering. The method for obtaining the desired information in these areas centered on the creation of a benchmark questionnaire.

Areas of general interest included Inhstructure, Computer Platforms and Networking, and Organizational Structure. The focus arm included Human Resources, Information Management, Manufacturing Software Tools, and Standarda/ Policies and Practices. The benchmark team identified key areas of interest, both focused and gencml. As a result of this efforL changes are recommended that will enable Y-12 to become a more responsive cost-effective manufacturing facility capable of suppordng the needs more » of the Nuclear Weapons Complex and Work Fw Others into the 21' century. The companies visited included several large established companies and anew, small, high-tech machining firm. The mission of the benchmark team was to search out industry leaders in manufacturing and evaluate lheir engineering practices and processes to determine direction and focus fm Y-12 modmizadon efforts. The Benehmark Project was created from a desire to identify best practices and improve the overall efficiency and performance of the Y-12 Plant's systems and personnel supprting the manufacturing mission.
