Interchangeable part for workpiece fixture

A system comprising:

• a workpiece fixture, comprising:
• a surface formed cylindrically, at least in parts, relative to a rotation axis as a radial bearing surface for an interchangeable part, at least one stop face or stop pin which protrudes from the workpiece fixture substantially radially relative to the roation axis and serves to cooperate with at least one ramp of an interchangeable part in the axial direction relative to the rotation axis, and
• a second locking element adpated to cooperate with a first locking element of an interchangeable part to create a locked interchangeable part;
• and
• a interchangeable part, comprising:
• a first end for receiving a type of workpiece adapted thereto and a second end for fixing the interchangeable part on the workpiece fixture, wherein the second end has a face having at least one ramp extending in a circumferential direction relative to a rotation axis, and
• a first locking element adapted to cooperate with a second locking element of a workpiece fixture to create a locked interchangeable part, wherein the first locking element and second locking element permit separation of the locked interchangeable part from the workpiece fixture only if a minimum force is overcome.
