Strain measurement has become a valuable tool for monitoring deep drawing operations. Measured strain data are used to characterize the safety margin of the forming process. The comparison of actual strain values with the formability limit (FLC) of the sheet metal material provides essential information needed for assuring a stable and efficient deep drawing production flow. AutoGrid® measuring technology has become the proven solution for strain analysis in an industrial environment of a stamping plant. AutoGrid® comsmart provides an automated, user-friendly solution for application of high-precision photogrammetry. The autonomous measuring head guarantees convenient operation; it is battery powered and cable-free.
A single button trigger records a set of 4 synchronized cameras with 5 million pixels resolution. The data can be transferred online or stored for later transfer. An integrated display allows the visual image control in measuring mode.
