MARKET TRENDS AND ISSUES
Advancement of AHSS
?Fractures and splitting issues on traditional presses
?Increased wear driving up tooling costs
More Vehicle Models
?Driving flexibility and responsiveness
Speed to Launch

?Start/stop versus continuous strip motion
?Multi-axis adds to tolerance
Customer was experiencing splits in the forming process with blanks cut from 2-mm thick AHSS in a traditional blanking press operation.
After multiple attempts to resolve the problem with the steel supplier and through blank shape changes, the customer tried laser cut tryout blanks.
?It was determined that the mechanical blanking caused micro-fractures
?The laser cut blanks eliminated the micro-fractures
?Production of these parts continued using laser blanking
CUSTOMER CASE 2: OPERATIONAL RESPONSIVENESS
Customer was experiencing downtime due to problems keeping a blanking die running when standard tooling was put into use with high-strength steel.
Blanks were sourced for laser cutting while the tooling was being reworked to accommodate the new high-strength materials.
?CAD data was generated by scanning a finished blank
?The laser line was programmed and ready to cut before the first coil arrived at the facility for interim production
A mechanically cut blank required an additional precision shearing operation to prepare the edge prior to a welding operation to produce tailor welded blanks.
Blanks were sourced for laser cutting to avoid the second shearing operation.
?The resulting laser edge did not require a secondary shearing operation
?The coil width was reduced by 12-mm creating additional savings
Customer did not have updated blank shape CAD data. The blank shape was modified to accommodate features in the forming dies, but the updated information was not documented.
A sample blank was sent to LaserCoil and was scanned to produce dimensional CAD information. Using standard LaserCoil software the CAD files were imported and converted automatically into nesting routines.
?Time savings over manually generating paths
?Automated generation of optimized cutting paths
?Material savings from optimized nesting patterns
