1kg Challenge Project
Our Workpiece Design
We designed a drill bit with cooling channels internally as coolant holes allow the cutting fluid to flow through and cool down the drill bit and the workpiece, extending tool life and preserving the material's integrity.Inspired from what we have learnt in our Additive Manufacturing (AM) lessons, internal channels are some of the highly intricate designs that conventional manufacturing has difficulties in achieving. Our focus for the challenge is a project with complex geometry, internal channel, functionable and sustainability. Hence, we adopted metal 3D printing technique to fabricate a drill.
Differentiation + Customization
Whilst there are already coolant drill bits in the market, we tried for 3D printing a Ti64 coolant hole drill bit to differ from the norm.
With 3D printing adopted in drill bits, the design and structure of internal cooling channels can be customized in the technological sophistication of various cutting tools.
Functionality Factor
For functionality wise, the printed drill has to undergo a grinding process for the drill bit to achieve its cutting edges and dimensional accuracy.
