EDGE SCAN is a 5-axis CMM tactile scanning technique. It drives the CMM in a uniform direction to minimize the inherent inaccuracies of the CMM structure while the system adapts to the changing surface shape by controlling the contact pressure of the stylus.
EDGE SCAN is well suited to the measurement of airfoil leading edges and similar contours.
Verisurf’s Full-Featured CAD Enhances CMM Pathing
Verisurf’s CAD foundation enables us to better recognize surfaces and create complex CMM scanning paths to gain superior performance from 5-axis CMM scanning technology.
KEY BENEFITS
Along with modern CMM head, sensor, and controller technologies, new 5-axis pathing methods from Verisurf software deliver high-performance measuring speed and flexibility. Furthermore, it’s achieved while avoiding the speed-versus-accuracy compromises inherent with conventional methods.
Five-axis motion allows the stylus to follow a continuous path along complex contours without leaving the part surface to index the probe angle or change the stylus. Controller algorithms synchronizing CMM and head motion, produce optimal probe paths that minimize dynamic errors.
There are extensive productivity gains offered by 5-axis probing, as it dramatically reduces the number of setups and special fixturing. It also allows fewer probe changes and requirements for unique probes, which are common in 3-axis probing.
- 5-axis measurement technology achieves 15% to 50% cycle time savings
- Minimizes the dynamic effects of CMM motion at high measurement speeds
- Is ideal for complex, 5-axis machined, mill-turned, or additive-manufactured parts
- Up to 5 times faster to program and setup a 5-axis versus 3-axis CMM
