In CIM environment flexible the design that clip runs a system and implementation

1 foreword faces an user increasingly as the product, bring about a product in order to add additional change to breed increases and design alteration for manufacturing system of the feature. Use flexible production system (FMS) technology is meant make and assembly line does not suffer sheet to plant the limitation that the spare parts produces, and truly flexible production the biggest obstacle is clamping apparatus not beyond the mark and special, adjustable whole, cannot rapid and automatic change. Accordingly, flexible production system wants well-known symbol actually flexible, clamping apparatus also must be flexible. The introduction is in below the computer is compositive production environment (inside CIM) flexible the program that clip runs subsystem and implementation, reach the introduces pair of whole CIM environments influence of subsystem of this kind of automation, discuss the join of subsystem data structure and compositive method with prospective activity at present. 2 flexible clip supports strategy the special sex to reduce clamping apparatus, current researcher is replacing traditional clip to support new approach of the method in development, namely flexible clip is held. Flexible clip is held even if use a kind of global mix to run a system, for gens production working procedure secures the work of all sorts of appearance and dimension. Use the good point with this kind of the mainest unit to have: · reduced the time of design, production special fixture and cost. · saved the pay that provides reduplicative special fixture. · enhanced program and process designing ability, change of design of the small lot in be opposite is big, the product that faces an user but efficient and seasonable offer money. Flexible the development that clip runs a system is depended on greatly contemporary of the CAM of ／ of CAPP of ／ of CAE of ／ of main component CAD that make and assembles a system and automation of robot ／ factory compositive. What had put forward at present is flexible with the design that gets used to clamping apparatus oneself plan is like a graph 1. Using module type clamping apparatus to locate and tighten firm work is the conception of German researcher, use at machine treatment foreword normally. Module clip maintains a standard is to use all sorts of foundation cell, like V model piece, rectangle piece and clip are held go decorating, pay clamping apparatus, these component bolt secure the T that taking straight aperture or cone-shaped aperture model on groovy board or motherboard (, kind it is) of face of machine tool bed, use measurement unit (wait like height gauge, dial gauge) adjust fixed position accurately. If prepare to process the work of an above, use ancon lever clamp normally, so that change quickly,be versed in. Clamp changes workpiece to be pressed closely in V model piece and secure on rectangle piece datum plane. At present the research of this respect is using a robot to finish clamping apparatus automatically to assemble centrally, reach development to design the software system that clamping apparatus assembles automatically. Can match clamping apparatus and module type clamping apparatus again similar, it also is to use can recombine in great quantities, but the component of reorder, form the stated fixed position that hold clip, close solid all sorts of workpiece. These component are comprised by the positioner of different measurement, clamp normally, still use bearing sometimes. The job that clip holds component to recombine is in by robot or outfit commonly the special unit in the system is finished. These component are gotten from storeroom by the robot and move put on clamping apparatus platform, then adjusts clip to hold, secure work. Now oneself roll out a few commodity, be like " the 5 unit of DEA " use at the car to operate screen examines, GFM company is used at aviation industry flat to mix arc board spare parts cuts edge working procedure to wait can distribute clamping apparatus system again. 3 computers are auxiliary and flexible clamping apparatus designs (CAFFP) is flexible clip holds a system to separate a side: It is development analysis, test and verify and the software that make automation system place automatically need, 2 it is the hardware that develops all sorts of production processes. Software must have the following function: · pretreatment: Retrieve appearance of spare parts geometry from CAD database or similar data switch device. Layout of · clamping apparatus designs: Regulation of knowledge of have the aid of and fixed position of option of production process information and clip oppose an aspect. · designs an analysis: Those who finish a design center to have position is far move learn to learn an analysis with force. · clamping apparatus chooses: To concern process (if assemble, solder, machining) choose particular package. Test and verify of · clamping apparatus: Design the effect of clamping apparatus layout according to the place of production process test and verify of the program. · interference detects: The figure that provides center to have unit is emulated and decide periodic time () of Rp cost estimation. · aftertreatment: Generation center has unit program, the data file that makes place need resource (detailed list) . Nextpage pursues the 2 structures that show CAFFP system. Must point out, different production process perhaps should be developed a variety of flexible clip runs a system, because clip runs a kind of production course,this is (if assemble) the requirement of workpiece has not at another production process (be like machine add) requirement. Accordingly, the hardware development of these systems should suit with production process photograph, or suit with the gens process look that has identical or similar clip to hold. In 4 CIM environment flexible the design that clip holds and the design that realize clamping apparatus and process designing are the computer auxiliary craft is designed (the main task in CAPP) , it is CIM be designed in the environment and produce the join chain between. Clamping apparatus engineers a system to have a few arrangement, the other activity in must designing medium other job and CIM with craft is compositive together. Compositive cent is technology and function two class. CAFFP needs to change products plan branch the information about appearance of spare parts geometry (namely CAD data) , such information can express format B for border, Rep, or be like IGES according to exchanging a form through number. Want to design significant clamping apparatus position, must craft designs information, be like machine add cutting tool contrail: Workmanship, be like exterior surface roughness. CAPP system must the machine tool, the message that robot and clip run a system and program offer manufacturing section (workshop) , basically do not need to return information. In addition, production attempers and control (the resource information that PPC) needs to make a product. This kind of data mirrors the device that gives need, clip to hold system, handling time to wait, plan for PPC and attemper resource. Graph the 3 sketch map that the group runs each in showing CIM environment. Technology design and clamping apparatus design can resemble design and analysis to be united in wedlock in that way have rice, form the CAPP in depicting a model. Functional module provides the iformation flow of other activity. Must point out, with respect to textural compositive and character, iformation flow very count firm model, because current and other information need between departmental door. As a result of the CIM that stops really compositive and current expenditure is too tall, and. Still put in a few controversies (if assure data redundancy, make information straightway) , the islands that reason can build a few to be able to realize fruit of requirement market effect (if pursue 3 black thick round) . 5 conclusion are flexible design and create a demand what clip holds a system to aim to reduce special fixture, at present industry the system is being used in the factory. Accordingly, clamping apparatus designs the substantial that assists technology design as the computer, with the main function of CIM environment, of the focal point that will make prospective CIM work, .
