 XTSM Strain measurement system for sheet metal forming grid The strain measurement system of XTSM sheet metal forming grid takes stamping image with high resolution digital SLR camera or measuring head with industrial CCD camera, and then calculates the spatial coordinates of small circle points produced in multiple photos with high accuracy by photogrammetry. The deformation and strain distribution of parts, hot spot area and thickness variation of sheet metal can be obtained (assuming the volume remains unchanged), and calculate 3D Deformation of sheet metal. XTSM Model Product advantages High precision and high resolution It has high measurement resolution and accuracy to meet the needs of different measurement ranges, including small size sheet metal parts and large complex parts (such as automobile sidewall). Verification and optimization of finite element
simulation results Full-field strain data of stamped parts can be obtained conveniently and quickly by using XTSM system, including 3D coordinates of parts surface, strain values (principal and secondary strains), material thick-ness reduction data, forming limit diagram (FLD) and sheet metal hardening, etc. Optical measurement technology combined with mesh strain calculation method It is suitable for analyzing the forming process
of various materials. By means of forming limit diagram (FLD), the measured
strain values of parts and components are compared with material forming limit
curve (FLC), and the forming process is judged and evaluated intuitively. Applications ● Sheet metal deformation strain measurement
