Thermal Drilling with Force-Feed Tool

vibration drilling tool and thrust force investigation in vibratory drilling process of al 2024-t6

vibratory drilling (vd)process is a new modern technology where longitudinal wave with high frequency (more than 16 khz) and low amplitude (usually between 2 up to 30 µm) is superimposed on the movement of cutting tool, resulting in connection and disconnection of cutting tool engagement with workpiece. in this study, in order to perform vibratory drilling process, two vibration tools are desig...

Telerobotic-assisted bone-drilling system using bilateral control with feed operation scaling and cutting force scaling

BACKGROUND Drilling is used in the medical field, especially in oral surgery and orthopaedics. In recent years, oral surgery involving dental implants has become more common. However, the risky drilling process causes serious accidents. To prevent these accidents, supporting systems such as robotic drilling systems are required. METHODS A telerobotic-assisted drilling system is proposed. An a...

Application of Design of Experiment Method for Thrust Force Minimization in Step-feed Micro Drilling

Micro drilled holes are utilized in many of today's fabrication processes.Precision production processes in industries are trending toward the use of smaller holeswith higher aspect ratios, and higher speed operation for micro deep hole drilling. However,undesirable characteristics related to micro drilling such as small signal-to-noise ratios,wandering drill motion, high aspect ratio, and exce...

Thermal Response Test While Drilling

Knowledge of the ground thermal conductivity is of importance when designing borehole heat exchanger (BHE) systems. As thermal conductivity for any specific rock type varies due to its mineral content, porosity, pore fluid and anisotropy, it is preferable determined in-situ. Choudhary (1976) suggested a method for determining the thermal conductivity which analysed the heat transfer during the ...
