Abstract
A method of forming an opening in a layered structure includes providing a layered structure including a first layer and a second layer and a near-zero gap interface defined between the first layer and the second layer; providing an opening through the layered structure such that the opening extends through the first layer and the second layer; and working simultaneously the opening in the fay surface of the first layer and the opening in the fay surface of the second layer without separating the first layer and the second layer. An internal chamfering device is also disclosed.
Claims18
A method of forming an opening in a layered structure, comprising:
- providing a layered structure including a first layer and a second layer, a near-zero gap interface defined between said first layer and said second layer and a first fay surface on said first layer at said interface and a second fay surface on said second layer at said interface;
- providing an opening through said layered structure such that said opening extends through said first layer and said second layer;
- providing an internal chamfering device comprising a device housing and a tool bit extendable from said device housing;
- and
- working simultaneously said opening in said fay surface of said first layer and said opening in said fay surface of said second layer by inserting said internal chamfering device in said opening and extending said tool bit from said device housing of said internal chamfering device without separating said first layer and said second layer.
An internal chamfering device, comprising
- a generally elongated device housing having a tool bit opening;
- a cam bar provided in said device housing and displaceable along a longitudinal axis of said device housing;
- a slot depression provided in said cam bar;
- a tool bit slot provided in said cam bar and extending along said slot depression;
- a tool bit slidably engaging said tool bit slot and extendable through said tool bit opening;
- and
- a magnetoresistive tracking probe carried by said tool bit and a main giant magnetoresistive probe provided in said device housing in spaced-apart relationship with respect to said magnetoresistive tracking probe.
