Abstract
Abstract An end mill is used to form a reduced thickness step in an indefinite length of strip material. If, due to tolerances and other factors the reduced thickness material is slightly too thick, it is swaged to a reduced thickness following which terminals are formed of both the thinned and original thickness material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
91 words
Apparatus for forming crimp type terminals from an indefinite length of strip stock including end mill cutting means for reducing the thickness of a longitudinally extending portion of the strip stock to a thickness greater than a given minimum thickness, means for assuring that the thickness of the reduced thickness portion of the strip stock is not greater than a given maximum thickness tolerance and means for cutting out terminals from the strip stock with the terminals including a crimp barrel formed from the reduced thickness portion of the strip stock.
Claim 2
Dependent Claim
91 words
Apparatus for forming crimp type terminals from an indefinite length of strip stock including end mill cutting means for reducing the thickness of a longitudinally extending portion of the strip stock to a thickness greater than a given minimum thickness, means for assuring that the thickness of the reduced thickness portion of the strip stock is not greater than a given maximum thickness tolerance and means for cutting out terminals from the strip stock with the terminals including a crimp barrel formed from the reduced thickness portion of the strip stock.
Claim 3
Dependent Claim
88 words
Apparatus for forming crimp type terminals from metal strip stock including milling means including an end mill and feed means for moving the strip stock past the end mill for reducing the thickness of a part of the strip, means for reducing the thickness of portions of said part of the strip if such thickness is greater than a given maximum thickness tolerance and means for forming crimp terminals from said strip stock with crimp barrels formed from said portions of the reduced thickness part of the strip.
Claim 4
Dependent Claim
88 words
Apparatus for forming crimp type terminals from metal strip stock including milling means including an end mill and feed means for moving the strip stock past the end mill for reducing the thickness of a part of the strip, means for reducing the thickness of portions of said part of the strip if such thickness is greater than a given maximum thickness tolerance and means for forming crimp terminals from said strip stock with crimp barrels formed from said portions of the reduced thickness part of the strip.
Claim 5
Dependent Claim
44 words
Apparatus as in claim 2 wherein said means for reducing the thickness comprises a strip support and a swaging tool moveable toward and away from said support, the distance from said tool to said support when bottomed being equal to the maximum thickness tolerance.
Claim 6
Dependent Claim
26 words
Apparatus as in claim 3 including punch means for forming displacement relief windows in the reduced thickness part of the strip located adjacent said strip portions.
