Bone drilling: an identification of heat sources

Optimal Sensor Location for the Identification of Moving Heat Sources

For many thermal processes described by partial differential equations, parametric identification of the model can be performed by solving an inverse problem. Measurements noises occurring on one or several measured characteristic states have to be carefully taken into account in order to provide robust identification procedures. However, spatial inaccuracy of the sensor location is rarely inve...

ultrasonic assisted drilling of bone

ultrasonic assisted drilling (usd) is new technique to drill difficult to machine materials. in this method, tool or workpiece vibrates with amplitude of few microns in addition to conventional drill bite rotation. in this experimental research, the bone was drilled both conventionally and using uad, then the thrust was measured in two methods at feed rates of 50, 75 and 125 mm/s and 500, 710 a...

An Experimental Research on Bone Drilling Temperature in Orthopaedic Surgery

The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to mea...

An experimental investigation on thermal exposure during bone drilling.

This study presents an experimental investigation of the effects of spindle speed, feed rate, and depth of drilling on the temperature distribution during drilling of the cortical section of the bovine femur. In an effort to reduce measurement uncertainties, a new approach for temperature measurements during bone drilling is presented in this study. The new approach is based on a setup for prec...
