In a product life cycle the largest investment is always the tooling, this is especially true in investment casting. Until now the actual geometry of the wax die has been largely unknown. Level 3 Inspection can use White Light Scanning (WLS) with computer-aided-inspection (CAI) to compare the wax die to the CAD model, other wax dies and scans of the same die taken over a period of time, to trend wear. This technology gives our customers a new and profound insight into the size shape and geometric conformance of wax dies that they have never had before. By inspecting and perfecting the actual wax die Level 3 can help their customers quantify shrink rates, identify problem areas in the die and bring better castings to market, faster than ever before.
CMM captures only a few points in the time that WLS can capture hundreds of thousands, so Level 3 is able to do a more thorough inspection. The results are much more visual and therefore much more easily understood and interpreted.
Inspecting injection molded products with complex free form geometry poses some unique challenges and is difficult using a CMM system, which depends on points that to show whether or not the part is conforming within the allowable tolerance. Often, there is not enough point data to make an accurate comparison.
Level 3 Inspection’s customers are moving quickly to statistically based inspections in which the qualification is based not on a single piece, but on a sampling of parts, new part inspection would take much longer to complete without the ability to automate portions of the process.
Traditionally, studies based on a sampling of parts are done using CMM to generate metrics on dimensions for each part. This is a time-consuming process, since each part must be measured individually. Data is then typically transferred to an analytic program, evaluated, then published.
Speed is the key. Speed of inspection is always Level 3 Inspection’s main challenge. Everyone wants the results yesterday and our process is helping us deliver more complete results much quicker.
