Typical US Industry Approach

Extensive manual bearing adjustment time with focus on gate milestones

Single panel dimensional QI focus with single panel quality gate milestone approval

Shift to assembly QI after single panel milestone gates are met

Final step minor match to body just before SOP if required

Typical HIROTEC Approach

Manual bearing adjustment is considered non value add. Trust machining accuracy and remove hard spots

Single panel dimensional QI focus for major dimensional and formability issues

Quickly move into assembly QI and target assembly dimensional quality milestone

Final step minor match to body just before SOP if required

Part Coordination Fixture (PCF)

Duplicate of all GEO net pads and clamps

Allows for individual part inspection (except for outer panel)−HIROTEC philosophy is no checking fixture for the outer panel

Allows for assembly of inner sub

Surface Distortion Compensation

Strain Analysis

“Analysis” Estimation

Data Insert

Surface distortion is evaluated in simulation

Compensation is added based on historical data

Compensation is confirmed in simulation

This process results in a significant reduction in highly skilled hand work during the tryout process

Laser Surface Buildup Welding

Manual surfacing welding

−Highly dependent on operator skill

−Difficult to accurately control thickness

−Longer machining times

−High heat input

• Potential for cracking & warping

Laser surfacing welding advantages

−Predictable buildup dimensions

−Low risk of voids and additional repair

−Low heat input

• Shorter machining time

• No cracking or warping

−Reduced cycle times

−Elimination of operator weld skill requirement

Laser Surface Buildup Die Example

Laser cladding

−Example of 15mm die surface buildup

Laser hardening of stamping dies

− In addition, the laser system can also be used for CNC surface hardening

• Very accurate, consistent hardening

• Reduced heat input

• Reduction in highly skilled labor

Hammer Peening Surface Treatment

Hammer Peening Advantages

−Reduction in surface machining time

−Elimination of most surface hand work

−More consistent friction coefficient match with material flow simulation resulting in better virtual world to real world match

−Side benefit of improved surface hardness during die tryout stage

−The above results in a significant reduction of high skilled labor input

−And shorter tryout times improving speed to market
