Drilling procedure is widely used in orthopedic surgery to position reduced fractured bones and prosthetic components. However, successful execution of bone drilling requires a high level of dexterity and experience, because the drilling resistance is large and sometimes vibrates violently to difficultly grasp the hand-piece or even break the slender drill. This paper introduces haptic function...

Training systems for dental implantology that are based on virtual reality need a precise haptic feedback with six Degrees of Freedom (6DoF) This is particularly challenging when using real patient data for the jawbone and during the interactive simulation of drilling. In this paper, we present our simulator and two complementary contributions: The first one is a method for 6DoF haptic renderin...

Drilling automation is a rapidly growing area of information technology development. Efforts within automation are being undertaken by numerous and diverse organizations in the oil and gas industry, partly due to a desire for exploitation of marginal and complex fields, and partly in order to increase safety of high risk operations. As offshore drilling occurs in a unique work environment, orga...

A virtual teeth drilling system whose basic aim is to be used for the training of dental students in the handling of drilling instruments is presented in this paper. A 3D model of the face and the oral cavity is utilized by the application. This model can be adapted to the characteristics of a specific person and animated. Drilling is performed within the oral cavity, on realistic teeth models ...

Situation Awareness (SA) issues are often identified as contributing factors to drilling incidents, most recently in the Deepwater Horizon blowout. Two studies aimed to identify the cognitive components required for offshore drillers to develop and maintain SA whilst controlling subsea hydrocarbon wells. In study one, critical incident interviews were conducted with 18 experienced drilling pers...

This paper presents a new methodology to predict the wear for three-cone bits under varying operating conditions. In this approach, six variables (weight on bit, rotary speed, pump rate, formation hardness, bit type, and torque) were studied over a range of values. A simulator was used to generate drlling data to eliminate arrors coherent to field measurements. The data generated was used to es...

This paper presents several new metrics related to bone removal and suctioning technique in the context of a mastoidectomy simulator. The expertise with which decisions as to which regions of bone to remove and which to leave intact is evaluated by building a Naïve Bayes classifier using training data from known experts and novices. Since the bone voxel mesh is very large, and many voxels are a...
