Abstract
Abstract A device for use during single point tool turning operations on lathes to monitor and limit tool force with additional utility as an adaptive control sensing mechanism. Four compressible load cells produce electrical signals proportional to the force exerted upon them. The load cells are located and entrapped between two parallel plates that are connected by a pivot or flexure joint and the entire device is positioned between the tool and tool bar.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
83 words
A tool force monitor to limit force during turning operations on a lathe comprising two plates held in a parallel position by a substantially planar flexure joint connecting the two plates and four compressible load cells with electrical leads entrapped between said plates, one of said plates being attached to the tool bar of the lathe, and the other plate being attached to the tool holder of the lathe, and two of said load cells situate on each side of said flexure joint.
Claim 2
Dependent Claim
