Development And Application Of CAD/CAM In FMS For Sheet Metal

FMS (Flexible Manufacture System) is a kind of advanced manufacture technology and system, which integrate the computer technique the number control technique the automation technique the producing management technique and information technique , and it has become a modern mode of the machine manufacturing, and could have achieved the maximal benefit in the produce of various kinds and medium or little batch.From the characteristic of CAD/CAM system of FMS for sheet metal, the topic presents the technology requirement the design conception and the system frame of realizing it; Pointing to the questions, in the practical application of CAD/CAM system of the FMS-II for sheet metal in Shanghai No.2 Textile Machinery Ltd. Co., the article put forward the solution of the operational foundation based on the PC with the second development of CAD software with the tool of ObjectARX, and mainly introduce measure the step and important technology of the rebuilding realization of the system of CAD/CAM, using in FMS-II of machining sheet metal.On account of FMS-II adoptiving the special system named the CAMPATH FDM-III, it causes that the FMS-II can not be integrated in the condition of CIMS, and for the CAMPATH FDM-III system being composed and based on the inside of itself, it makes that the data of produce can not be directly shared with other economy. In addition, the hardware of the system is worn gravely, the low version of the software is out of date, the drawing operation is inefficient, and it can not be realized the standardization,so the requirement of the present produce could not be satisfied.For resolving those questions, it needs to freshly exploit a CAD/CAM system of FMS-II. The target is that it begins with the information of the graph (based on PDM) used to directly depict parts, being supported by the currency CAD/CAM system, receiving the producing information by interact with manual, matching the cutter with expert system, building the data of the cutter location (CL) by account, finishing the optimising arrangement, creating the NC program for the numerical control system of the FMS-II of sheet metal by the post system, automatically processing the produce by the NC machine tool according to the CL, and then realizing the opening integration of the system of CAD/CAM system of the FMS-II for sheet metal, basing on PDM.
