Abstract
Official abstract text for this publication.
A through-hole depth measurement device includes a cutting force sensor configured and mountable in a position to sense cutting force exerted by a drill bit of a drill against a workpiece or stack of workpieces. A controller is coupled to the force sensor, is coupleable to a workpiece surface position sensor, and is configured to record the through-hole depth of the workpiece or stack of workpieces in response to signals received from the workpiece surface position sensor when the drill bit reaches a drill bit exit point. The cutting force sensor is configured and positionable to sense cutting force transmitted between a drill spindle and a spindle housing.
First claim
Opening claim text (preview).
What is claimed is: 1. A device for measuring the depth of a through-hole formed through one or more workpieces, the device comprising: a cutting force sensor configured and mountable in a position to sense cutting force exerted by a drill bit of a drill against a workpiece or stack of workpieces; a workpiece near-side surface position sensor comprising a pressure foot supported for reciprocal motion along a pressure foot axis, and further comprising a pressure foot axis positio…
