SCIEMETRIC SOLUTIONS
SCIEMETRIC SOLUTIONS Cylinder Head In-Process Testing: Valve Assembly, Stem, Key, and Cap Verification Highlights: •
•
Defect detection & classification • • • • • •
One or both keys missing One or both keys misaligned Cap missing Wrong cap orientation Valve missing Wrong valve height
•
Valve stem diameter
Comprehensive and graphical representation of test specimen
• • • •
100% data storage for traceability and process control On-screen diagnostics for sensor alignment and/or calibration verification Password protected on-line pass/fail criteria definition Utilizes existing sensor array and mechanicalfixture(s) for quick and cost effective retrofit
Utilizing built in Signature Analysis and real-time data processing, Sciemetric’s 200 product family and its operating software InspeXion® combine together to provide verification of the assembly quality of automotive cylinder heads. Compatible with test stations equipped with a variety of non-contact sensors such as focused beam ultrasonic or focal laser, a Sciemetric Signature Analysis System provides an unparalleled approach to key detection and valve stem measurement. The system conditions and acquires sensor inputs as the fixture performs a series of longitudinal and/or latitudinal scans across the top of an engine head. Depending on sensor type and mechanical fixturing, InspeXion® is capable of determining the integral parts of the intake and exhaust valves and their relative displacement. Performing 100% sampled data processing and Signature Analysis, compensating for variations in sensor orientation and alignment by implementing built in mathematical functions to normalize waveforms, and comparing segmented waveform data against statistically derived or user defined limit windows, the system provides reliable real-time pass/fail results.
VALVE STEM
Robustly packaged within an industrialized, stand-alone chassis, the Sciemetric Signature Analysis System is also able to utilize its integrated networking support for information and data exchange with down stream assembly and test stations and repair bays, resulting in significant time and cost reductions. Comprehensive and graphical representation of specimen profile, user definable operator menu system, and on-screen setup and diagnostics rounds out a highly intuitive HMI and dependable solution to this unique application. The valve assembly verification is one of many powertrain in-process testing applications Sciemetric has implemented around the world.
