<p>A thrust and torque sensor is provided for an automatic drill so as to result in an efficient drilling operation for laminated materials. Sensors are placed in one instance in conjunction with a spindle (42) and in another instance to a shaft in the drive train so as to sense the thrust and torque placed on the spindle. In a preferred manner, a yoke (44) with strain gauges (58, 59) is connected to a bearing race (43) on the spindle (42) to sense thrust and strain gauges (62, 63) are placed on a beam (51) connected to a shaft to sense torque. Signals from the strain gauges are then employed by a computer to control the drill.</p> |
