Methods and systems for controlling the operation of a tool

Allen Carl, +8 more
TLDR
Methods and systems for controlling the operation of a tool are provided in this paper, which can be applied to a broad range of tools and machining processes, such as a surgical drilling process, for the drilling of bone.
Abstract: 
Methods and systems for controlling the operation of a tool are provided These methods and systems may be used to control the operation of any tool, for example, a drill or a saw The methods and systems employ at least one sensor to detect at least one operational parameter of the tool, for example, drill speed or acceleration Instrumentation is used to process the data representing the parameter to determine characteristic values of the parameter, for example, amplitudes and frequencies These characteristic values are used to control the operation of the tool, to determine one or more properties of the material being acted on by the tool, or to monitor the condition of the tool Though aspects of the invention may be applied to a broad range of tools and machining processes, in one aspect, the methods and systems are used to monitor and control the operation of a surgical drilling process, for example, for the drilling of bone

Variable speed DC motor controller apparatus particularly adapted for control of portable-power tools

Damon Germanton, +1 more
TL;DR: In this paper, a portable electric power tool having a DC motor for driving tool bit is controlled according to speed and torque by employing a zero displacement switch means which is coupled to the tool and operative to provide an output voltage porportional to the pressure applied to the switch means via the hand of the user.
