Peg-hole disassembly using active compliance.

ABSTRACT: When considered in two-dimensional space, a cylindrical peg being withdrawn from a clearance-fit hole can exhibit one of four contact states: no contact, one-point contact, two-point contact and line contact. Jamming and wedging can occur during the two-point contact. Effective control of the two-point contact region can significantly reduce resistance in peg-hole disassembly. In this paper, we explore generic peg-hole disassembly processes with compliance and identify the effects of key parameters including the degree of compliance, the location of the compliance centre and initial position errors. A quasi-static analysis of peg-hole disassembly has been performed to obtain the boundary conditions of the two-point contact region. The effects of key variables on the two-point contact regio
