Optimizovani i virtuelni model planiranja merenja na mašini

Abstract

Specifične potrebe kupaca postavljaju zahteve za fleksibilnošću i personalizovanim proizvodima, kao i brzim plasmanom na tržište. Masovna kastomizacija daje odgovor na ove zahteve i nameće nove potrebe unutar proizvodnih sistema kao što su optimizacija i virtuelizacija procesa obrade i merenja. Jedan doprinos u tom pravcu predstavljen je u ovom radu, a odnosi se na razvoj i verifikaciju modela merenja na mašini alatki. Cilj verifikacije je vizuelna provera kolizije između merne glave postavljene u prihvat alata i mernog predmeta na radnom stolu mašine. Virtuelni model planiranja merenja na mašini je realizovan na konfigurisanoj virtuelnoj mašini alatki LOLA HBG 80 u CAD okruženju. Merna puta je generisana novom metodologijom planiranja, potom optimizovana primenom kolonije mrava, programirana i verifikovana simulacijom za nekoliko standardnih oblika tolerancije. Izlaz iz simulacije je G-kod za realno merenje na mašini za delove srednje i grube klase tačnosti.

The specific needs of customers set requirements like flexibility and custom-made products, as well as quick placement of products on the markets. Mass customization responds to these requirements and imposes new demands inside manufacturing systems such as optimization and virtualization of machining and measurement processes. A contribution in that direction is presented in this paper, pertaining to development and verification an on-machine measurement planning model. The aim of the verification is to visualize collision check between the measuring head placed in the tool holder and the workpiece on the machine tool working table. The virtual on-machine measurement was realized on the configured virtual machine tool LOLA HBG80 in the CAD environment. The measurement path is generated by a new planning methodology, then optimized using ants colony, programed and verified by simulations through few examples of standard forms of tolerance. The output of the simulation process is the G-code for real on-machine measurement for prismatic parts of medium and rough dimensional accuracy.
