Virtual horizontal machining center LOLA HBG 80 for program verification and monitoring

Ovaj rad opisuje konfigurisanje virtuelnog horizontalnog obradnog centra LOLA HBG80 u okviru sistema za programiranje i verifikaciju, kao i u okviru sistema otvorene arhitekture upravljanja. Horizontalni obradni centar LOLA HBG 80 podržan je ekvivalentnom virtuelnom mašinom u CAD/CAM okruženju (PTC Creo i Catia), STEP-NC mašinskom okruženju, kao i u upravljačkom sistemu. Virtuelna simulacija je od suštinske važnosti za obradu, a razvijene virtuelne mašine koriste se za verifikaciju programa i monitoring procesa obrade. Virtuelna mašina u sistemu za programiranje omogućava verifikaciju programa pre slanja na stvarnu mašinu i može da uključuje verifikaciju putanje alata (CLF-Cutter Location File) i verifikaciju G-koda. U radu se takođe govori o mogućnosti primene novog metoda programiranja poznatog kao STEP-NC i pripremi odgovarajućeg okruženja koje uključuje virtuelnu mašinu. Virtuelna mašina u sistemu upravljanja predstavlja poslednji nivo za konačnu verifikaciju programa, kao i sistem za nadzor procesa.This paper describes configuring the virtual horizontal machining center LOLA HBG80 within the programming and verification system and the open architecture control system. The horizontal machining center LOLA HBG 80 is represented by an equivalent virtual machine in a CAD/CAM environment (PTC Creo and Catia), STEP-NC Machine environment, and the control system. Virtual simulation is essential for machining, and the developed virtual machines are used for program verification and monitoring of the machining process. The virtual machine in the programming system allows the verification of the program before sending it to the real machine and includes verification of the tool path (CLF-Cutter Location File) and G-code. The paper also discusses the possibility of applying a new programming method known as STEP-NC and preparing an adequate environment that includes a virtual machine. The virtual machine in the control system represents the last level for the final program verification and the process monitoring system

Configuring of 3-axis vertical CNC machine for rapid prototyping with two translatory and one rotary axes

This paper describes the configuration of a 3-axis vertical CNC machine tool for rapid prototyping with one rotary and two translational axes. The machine works in a polar-cylindrical coordinate system. The structure of the machine is C'OXZ. The virtual machine model is configured in the PTC Creo software environment. After configuring the virtual machine, the simulation of the CLF-based was performed in the mentioned software environments, and then the verification according to the G-code program in the Vericut software environment was performed. Programming and control of the configured prototype machine are realized in the LinuxCNC software environment, which is based on the PC platform. Also, in this paper, digital twin of machine realized in a python software environment is shown. The presented results show the proper functioning of the whole system

An overview of rapid prototyping technologies using subtractive, additive and formative processes

Ovaj rad opisuje metodologiju za primenu brze izrade prototipova primenom subtraktivnih, aditivnih i formativnih tehnologija na osnovu STL fajlova. Tehnologije brze izrade prototipova uključuju digitalni lanac informacija CAD/CAM /CNC, do nivoa koji omogućava uspešnu realizaciju fizičkih modela koristeći novu tehnologiju, dodavanjem, oduzimanjem i oblikovanjem materijala. U radu su razmatrane uobičajene tehnologije brze izrade prototipova, za koje je predložena generalizovana metodologija za njihovu primenu. Pokazane su i mogućnosti za verifikaciju programa pre same izrade modela. Metodologija je verifikovana na konkretnim primerima izrade izabranih delova koristeći tehnologije oduzimanja, dodavanja materijala sloj po sloj, i izrade kalupa (dodavanjem materijala) za livenje modela od silikona.This paper describes methodology for application of a rapid prototyping using subtractive, additive and formative technology based on STL files. Rapid prototyping technology includes using of a digital information chain CAD/CAM/CNC to a level which allows the successful realization of the physical models based on new technologies by adding, subtracting and molding material. The paper discusses about the usual technologies for rapid prototyping, for which a generalized methodology for their application has been proposed. The possibilities for program verification prior to the realization of the model were also shown. The methodology is verified on real examples of making selected parts. Used technologies are subtracting and adding material layers, layer by layer, and mold making (by adding material) for molding the silicone model

Configuring a virtual prototype of a BiSCARA robot

U radu je prikazano konfigurisanje virtuelnog prototipa BiSCARA robota generisanog na osnovu kompletno razvijenog kinematičkog modela robota. Ovako razvijeni virtuelni CAD model će omogućiti njegovu implementaciju u Python grafičko okruženje kao integralnog dela sistema upravljanja otvorene arhitekture razvijenog na osnovu prikazanog kinematičkog modela. Razvijeni kinematički model je obuhvatio rešavanje inverznog i direktnog kinematičkog problema, određivanje Jakobijan matrice i analizu radnog prostora. Verifikacija kinematičkog modela, odnosno konfigurisanog virtuelnog prototipa robota, je izvršena simulacijama kretanja vrha end-efektora prema zadatom programu u CAD/CAM okruženju.The paper presents the configuring of a virtual prototype BiSCARA robot generated on the basis of a fully developed kinematic model of the robot. The virtual CAD model developed in this way will enable its implementation in the Python graphical environment as an integral part of the open architecture control system developed on the basis of the presented kinematic model. The developed kinematic model included solving the inverse and direct kinematic problem, determining the Jacobian matrix and workspace analysis. Verification of the kinematic model, i.e. the configured virtual prototype of the robot, was performed by simulations of the end-effector tip movement according to the given program in a CAD / CAM environment
