OSG utilized Third Wave Systems product, AdvantEdge, to develop a brand new line for stainless steel WDO Drills. Using AdvantEdge, OSG was able to study chip shape and design improved drill geometries for chip evacuation.
CHALLENGE
Stringy and inconsistent chip shape in stainless steel from conventional drill resulted in poor part quality
The designers had to evaluate a large number of design parameters
AdvantEdge was brought in to help evaluate various designs to guide the design evolution and reduce the number of machine trials that would have been needed otherwise
APPROACH
Use knowledge from simulations to determine the best tool design for chip and temperature control, stability and high material removal rates
Model the drill and chip(s) in AdvantEdge to determine chip characteristics and evaluate improved drill geometries
IMPACT
A new drill geometry was developed that includes an altered cutting edge and groove shape, which creates consistently broken chips
