With a 5-axis solution for angled cutting chamfered cuts of material e.g. for parts that later are going to be welded and thus reducing one manufacturing step can be performed. This paper reports project work made in the MF2004 Machine Design advanced course at KTH. It describes the design and analysis of a first prototype (alpha prototype) of a 5-axis solution as well as the design of a second prototype (beta prototype). The selected concept is a tool center point (TCP) solution where the chamfer angle is realised by two rotations and the TCP position is independent of these rotations.

An FZG back-to-back gear test rig was used to investigate how the assembly and re-assembly of the same test setup affects the measurements. A spread in torque loss between one assembly and another of the same test setup were observed. Rig conditions also affected the spread in input torque. With knowledge of how the spread in torque loss varies due to assembly, test results could be distinguished between changes due to assembly and actual differences between tests.

Pre-absorption of patients' serum with Brazil nut did not modify the birchpollen immunoblot profile. Our results suggest that our patient had primary sensitization to Brazil nut, and that allergens other than the seed storage proteins in Brazil nuts may have a clinical role in allergic subjects.
