Redesign of Tool Holder for Superfinishing

Abstract [en]

Volvo Powertrain AB is the part of the Volvo Group which is responsible for the development and manufacturing of heavy-duty engines, transmissions and drive shafts. During the production of crankshafts, a method named superfinishing is used, to give the crankshafts the desired finish. In the current situation, the company has two different superfinishing machines working in parallel in the same process. The problem that arises is that the two machines remove different amount of material during the process, which causes problems since the previous stage of the process is common.The purpose of this Master of Science thesis is trying to equalize the material removal in both superfinishing machines, by doing a redesign of the tool holders (shoes) in the older superfinishing machine. To be able to equate the material removal a good understanding of the process, the two machines and the forces acting on the shoes are required. The shoes and their attachment in the two machines have been carefully studied to know how the new construction will be designed.The work resulted in a new construction of the tool holder for the older superfinishing machine with a longer arc, solid coating of polyurethane and a new type of attachment which enables self-adjustment of the tool holder to the crankshaft
