Researches On NC System For Plastic Door Window Sawing And Milling Center

Multi-function, high-flexibility, and intensive are the important direction of developing plastic door and window productions.By developing the CNC system and integrating CAD/CAM of the sawing and milling machining center(SMMC) for plastic door and window PVC profile, this paper is to discuss the key technologies including window design, process description, code generation, automatic control and system network and communication.The paper presents the developing status of the Plastic Door and Window industry, analyses and discusses the current actualities and subsistent problems of the CNC device and the CAD/CAM in the Plastic profile machining field. Based on the background of this project, the mainly researching direction has being advanced.We main researches the structure, the function and the process of the technologies of the sawing and milling machining center for Plastic Door and Window PVC profile. By developing secondly FANUC - 0MD system, the control system accorded with requirements of the SMMC is accomplished.This paper introduces feature technologies and databases accomplished the CAD/CAM scheme of the SMMC. Through in-depth studying feature technologies which are applied to the technical design for the SMMC, integration of CAD/CAM and automatic generation of G code are accomplished.We using vb.net to develop the CAM system.The seventh researches the communication between PC and CNC, provides a new mode of networking for CNC machine tools based on serial device server.
