Process modeling for robotic polishing
Abstract This paper presents the solutions adopted for a robotic polishing cell for mold manufacturing. Mold finishing is frequently carried out manually; these kinds of operations are iterative, time consuming and require experience. Automation can introduce cost reduction minimizing production times on such manual finishing operations. The research shown in this paper provides an overall solution without discarding aspects that could be relevant to the task considered in the mold making environment. Most of the mold makers usually employ CAD/CAM systems in order to design workpieces and to prepare the CNC programs to manufacture the parts, this CAD data can also be used to prepare programs for the actual robot finishing of these parts. In this work, an automatic planning and programming system based on data from a CAD system is described. The direct use of the paths implies difficulties of adaptation mostly when free-shaped surfaces are treated, so that the use of a constant contact force control has also been considered. To accomplish the automation of the process it is necessary to establish a behavior model of the system’s variables. This fact allows the definition of the task specifications of the tools and, as a result, both the planning system and the control strategy by stages of the polishing process.
On the Development of an Automated Adaptive Polishing System
The emerge of Industrial 4.0 revolution and influences to production, information, and communication technologies have made manufacturers capable of reaching higher performance in the last decade. Making smart operations has been set as a top strategy of manufacturing societies, and machinery industry as an integral part of production has been highlighted develop. Aerospace, automotive, metals, glass, and plastics industries have been pioneers to improve, optimize, and develop automated polishing as a final operation of surface finishing process considering of KPIs: quality, time, cost, and safety. In this review, after mentioning the state of the art of last relevant papers, some clues for future research will be presented.
A Study on the Experimental Analysis of the Automatic Fine Polishing System
Now a days, securing skilled workers is very difficult due to the hardworking environment. This situation will be getting worse in the future and also that makes the dies/molds industries difficult. In this research, the automatic fone polishing system which can be directly attached to the spindle of CNC machine is proposed and analyzed. The system is also controlled by the NC progra data created by CAD/CAM system. The usefulness and effectiveness of the developed system are verified more detail through some comparisons between automatic and manual polishing experiments. The experiments show that the automatic polishing is a more useful and effective process than manual one. For the application, this system can be easily used for the polishing process in the area of any fine surface.
