Off-Centre and Eccentric Deep Holes: Workholding Before Tooling
Treat an off-centre deep hole as a positioning and clamping problem first: see what the workpiece-stationary configuration unlocks, where a rotating …
Counter-Rotation in Gun Drilling: Relative Speed and Bore Evidence
Calculate relative rotation for a counter-rotating tool and workpiece, then distinguish speed arithmetic from evidence of improved bore geometry.
Guide Bushings and Workholding for Deep Hole Drilling: Separate the Contacts
Locate the entry bushing, outside shaft support and bore-contacting pad, then distinguish the workpiece datum and clamping record from the …
