2 years (15 August 2017 - 14 August 2019)

In this project, optimum tool geometry of variable helix and variable pitch based on chatter stability lobe diagram (SLD) created from modal analysis and cutting force coefficient determination were developed. The outcome are 3 irregular milling tools (12, 16, 20 mm) with coated and uncoated were produced. This prototype optimum irregular tools geometry achieved 20 percent more productivity than commercial regular milling tool in suppressing chatter

1. To evaluate the chatter stability from dynamic properties and cutting force coefficients determination from different tool sizes of prototype tools.
2. To design the prototype optimum irregular milling tools from variable helix and variable pitch geometry based on chatter stability and optimization algorithm.
3. To evaluate the machining performance of developed prototype optimum irregular milling tools geometry in automotive industry.

1. Intellectual Property :
   • Milling tool geometry calculator. As discussed with KPM panel during progress presentation, we have previous Patent in FRGS which cannot count for this PRGS. So, they suggested to have copyright(already have) and industrial design (process with agent).

This project propose a strategy on tooling development (tool geometry, machining process, coating, suppression) for machining industry improve 30% productivity with RM720 per year. In Sapura Machining, they spend RM2.4 mil per year for tooling purchase (RM200-300k per month). Cutting condition: 16 mm axial depth of cut and 2 mm radial depth of cut and Testing in the production line every 100 cycle to see roughness change.
