In this study, grinding operation was performed on a work-piece with an unknown shape. As the control strategy, hybrid force/velocity control method was utilized using a PID controller and an Active Disturbance Rejection Controller (ADRC). Both control structures were implemented on an experimental setup and the results were compared. Results show that significant amount of effort can be saved in grinding operation on a work-piece with an unknown shape due to the elimination of CAD model dependent path planning processes.

Prediction of the cutting forces for robotic grinding processes with abrasive mounted bits Açıkgöz, Kemal; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2015) In this study, cutting forces for robotic grinding processes with mounted bits are investigated. In the majority of the grinding literature, the grinding process is analyzed based on rigid grinding machines and larger size wheels. However, the robotic grinding systems involve small size tools. Therefore, currently there is a need to experimentally study the geometry and force relationships for mounted bits. In order to overcome some of the difficulties arising in grinding studies (e.g. need for dressing, co...
In vitro Comparison of Autoclave Polymerization on the Transverse Strength of Denture Base Resins Durkan, Rukiye; ÖZEL, MEHMET BİROL; Bagis, Bora; Usanmaz, Ali (Japanese Society for Dental Materials and Devices, 2008-07-01) The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control. i.e.. conventional water bath to polymerize result by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at 60 degrees C for 30 minutes followed by 130 degrees C for 10 minutes; and (III) autoclave polymerization at 60 degr...
PULSE SHAPE, EXCESS BANDWIDTH, AND TIMING ERROR SENSITIVITY IN PRS SYSTEMS - COMMENT TANIK, Y (1989-08-01) Several non-minimum-bandwidth partial-response-signaling (PRS) techniques were compared in the above paper (ibid., vol.COM-35, p.475-80, April 1987). One of the criteria used for the comparison was the robustness to the timing jitter. The commenter shows that according to this criterion the duobinary signaling technique is superior to the dicode scheme at low values of the roll-off factor, in contradiction to the conclusion in the original study. In reply the author agrees that the comment is correct and th...
Wax deposition in horizontal wells Ozbayoglu, M.E.; Demiral, B.; Kök, Mustafa Verşan (2000-01-01) In this research, wax deposition in horizontal well bores was studied. In a horizontal well, the main mechanism for wax appearance is the pressure change rather than the temperature change. Six different thermodynamic models were improved for horizontal wells by adding a pressure function, and a computer program was developed to simulate the precipitation phenomena in horizontal wells. Solid-liquid equilibrium constants for each pseudo-component were calculated. Critical pressures and overall solid mole fac...
Numeric Simulation of Time-Dependent Remodeling of Bone Around Loaded Oral Implants Eser, Atilim; Tönük, Ergin; Akça, Kıvanç; Cehrelı, Murat Cavit (2009-07-01) Purpose: The objective of this study was to investigate the time-dependent biomechanics of marginal bone around osseointegrated dental implants within physiologic loading conditions. Materials and Methods: The remodeling of marginal bone around a 4.1-mm-diameter, 10-mm-long implant was studied by implementing the Stanford theory into axisymmetric mathematical models simulating different bone support at the implant neck: 1-mm-thick cortical bone (model 1), 0.5-mm-thick cortical bone (model 2), absence of cor...
