Tooling Design Trial
Same as previous years, students who are taking EPD342 Design for Manufacture and Tooling need to test trial designed tool. This time, they need to produce pipe notching tool. To reduce time and material, they decided to share a few of the parts (Figure 1). At the same time, they also tested their mini project, smart tooling system. As usual, there are success stories and there are also reworked cases, but none consider failed. In the future, several aspects need to be taken into account including, deviation of the dimension due to heat treatment, wrong selection of die clearance value and also unexpected things happened like overcompressed on the spring and misallignment. Two major defect detected are high burr and incomplete cut, which both are caused by wrong calculation of the die clearance (Figure 2).

This project is a teamwork effort and progressive, Every team member need to participate and contribute. No such terms so called passenger. However, it is still happened and the role of the group member to handle it and avoid it from damaging the group.
I have shared the story about the tooling design project for 2024-2025 in the linkedin Part 1 to 8. Example links are as below.
