The numerical control processing and jig of Strengthen the plank part are designed
Abstract : M5-5 Strengthen the plank part some aviation products one of frame thin wall part, it need certain intensity and rigidity to play a supporting role mainly, it adopts the aluminium alloy material of LC9, can meet its performance demand . Aviation products single piece light to produce in batches generally, is it adopt numerical control process production to suit. Aviation products single piece light to produce in batches generally, is it adopt numerical control process production to suit. This graduation project design of subject content mainly including M6-6 little floor part numerical control process and hole with make up jig assemble two parts. Numerical control process part for entity foundation , numerical control processing technology rules make , cutter , cut consumption and choice , main shaft of rotational speed of model of part, and artificial numerical control of part process, utilize UG software turn into corresponding numerical control of process process the procedure automatically. Foundation, entity of model to utilize UG existing piece , round cylinder , cone , spheroid 4 kinds of simple entity models, is it set out to demand through modeling rationality and parameter , is it accord with the entity model processed in numerical control to establish according to M5-5 Strengthen the plank characteristic of part. According to thick, principle that finish machining separate work out the processing technology rules of numerical control rationally. And choose the suitable cutter and cutting consumption with the lathe according to the work piece material. Making the jig up has overall design which makes the jig up , relevant choices of making the jig component up to assemble mainly, orient the basic choice and choice of clamping the method and process the analysis of precision of error.
