| Product development with TRIZ: design evolution of deburring tools for intersecting holes
Chang-Hee Cho/Kwon-Hee Kim
The Journal of Mechanical Science and Technology, vol. 24, no. 1, pp.169-173, 2010
Abstract : 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.
