"Wedging is an event in which the contact forces between peg and hole can set up compressive forces inside the peg, effectively trapping it part way in the hole. To avoid wedging, one must keep the angular error between peg and hole at the moment of first 'two point contact' small enough. The equations describing succesful assembly, developed in Section 10.C.4, show that there is a relation between avoiding wedging and ensuring that the chamfers meet."
