1. An apparatus configured for working a workpiece, the apparatus comprising:
a first working tool;
a first motor coupled to the first working tool, wherein the first motor is configured for urging said first working tool along a first axis in a first direction against said workpiece;
an electronic controller communicatively-coupled to said first motor;
a manually-selectable workpiece characteristic selector communicatively-coupled to the electronic controller and is configured to send a manually-selected workpiece characteristic signal of a plurality of manually-selectable workpiece characteristic signals to the electronic controller, the manually-selected workpiece characteristic signal corresponding to a type of material from which the workpiece is formed; and
a sensor communicatively-coupled to the electronic controller, wherein the sensor is configured to detect a position of the first working tool along the first axis,
wherein the electronic controller is configured to:
translate the manually-selected workpiece characteristic signal into a calibrated force signal;
receive a sensed signal from the sensor corresponding to the position of the first working tool; and
based on the sensed signal, send the calibrated force signal to said first motor whereby said first motor drives the first working tool downward against said workpiece with a force in proportion to said calibrated force signal.
