Developing the control system for a Pin-on-Disc machine which will be used to measure friction in the contact while changing speeds and pressures in a short time interval.
During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. Since friction is such an important factor when aiming for a specific clamping force, it is of interest to simulate the contact and friction in the screw head to joint, and thread interfaces. This will lead to a possibility of gaining a deeper knowledge of friction characteristics when tightening, and how the dynamic friction relates to different coatings/materials and screw geometries. In the end, understanding friction behavior will make it possible to influence the quality of the assembly.
Design a robust and flexible control system for the Pin-on–Disc machine. Evaluate the different sensors relevant to the study of friction. Collaborate with another master thesis student working on the design and manufacturing of the Pin-on-Disc machine.
