Course Objectives This course aims to acquaint the students with "Distortion Engineering" which tries to solve distortion problem by a system-oriented approach. In contrast to classical methods, which try to eliminate distortion by production step base measures, "Distortion Engineering" considers the distortion as an attribute of whole manufacturing chain and optimizes the production by intelligent use of predictive and corrective methods.
Course Learning Outcomes The students who succeeded in this course;
  • Students will get acquainted with "Distortion Engineering" concept.
  • Students will cultivate understanding of distortion as a systems attribute.
  • Students will have understanding of the "Distortion Potential" and "Distortion Potential Carriers" such as asymmetries in the distributions of the alloying elements, mass, microstructure, residual stresses and texture.
  • Students will have hands-on-touch experience during laboratory sessions where residual stress measurements are conducted.
  • Students will cultivate understanding about the process chain design considering the evolution of distortion potentials.
Course Content Distortion, distortion potential, distortion potential carriers, compensation potential, production step based solutions, intelligent process chain design, predictive methods, use of in-situ measurement techniques and adaptive process control.
