Process control and damping are important to improve productivity, reduce chatter and improve part quality. This is especially important for brittle alloys such as gamma titanium aluminide.
IDEKO developed a self-adaptive process control system which reduced production time by 10% ncreased productivity by 300%.
FIDEA developed look-ahead and feed interpolation algorithms which limited jerk in critical regions. This reduced production time by 50%.
A tuned mass damper and variable pitch tools were developed to limit chatter, leading to good stability. The tools only work across a narrow range of frequencies, which is appropriate for materials such as gamma titanium.
IDEKO developed a damping table to increase dynamic stiffness.
CeSI developed an active damping device, ARES, which can be fitted on the spindle. This comes in high-stiffness, low-compensation and low-stiffness, high-compensation versions. These reduce cutting vibrations by 50% - 70%.
