Abstract:Double loop cutters arrangement can settle the contradiction between rotational inertia of
the tool magazine and the dimension limitation of the cutter head effectively, and increase the store of
tools. Disc type tool magazine with double loop cutters arrangement is designed and researched. The
spring steel 65Mn is used to manufacture elastic cutter fixture as the holding device for its inner and
outer loop tools. The dynamic deformation of elastic cutter fixture is discussed. The entire geometric
movement process of elastic cutter fixture from being opened by the tool holder to accomplishing the
whole action is analyzed. The effect and trend of inner stress caused by geometric deformation are
studied. Furthermore, the force condition in each part of tool fixture can be calculated, thus predicting
the motion stability and reliability of the elastic cutter fixture, and providing theory references for the
design of elastic cutter fixture.
