In this work, an example of product development based on TRIZ is introduced. The products are deburring tools for drilled intersecting holes which have been developed in two steps of evolution. Each step of evolution has been derived in the framework of TRIZ. The first design had limited access to burr edges on surfaces with mild degrees of curvature. The second design was derived from the contradiction analysis of the first design. Tests on the second design revealed problems with excessive cutting and tool damage. A third design was obtained from the physical and technical contradiction analyses of the second design. Tests were performed on aluminum alloy Al6061-T6 for various diameter combinations, cutting speed, and axial feed rate to confirm the performance of the third design.
