PFO SmartTeach

Features
Read full description

PFO SmartTeach is an application for your programmable focusing optics PFO. It facilitates generation and set-up of the laser welding and laser cutting programs you execute with the PFO. The integrated camera on the C-mount of the optics transmits the live image to the app. This enables you to teach comfortably right at the component. If you want to generate and teach-in PFO geometries, this can be carried out via intuitive, gesture-based operation on the iPad. Thanks to PFO SmartTeach you save a lot of set-up time โ€“ depending on the component this can be as much as 50%. PFO SmartTeach synchronizes the generated or changed programs with the laser. Users of the control software TruControl will adjust to it quickly because the familiar properties for generation of a PFO program have been retained. Known sequences and functions have been preserved. PFO SmartTeach can be tested without risk. For productive use, activate the option โ€œPFO SmartTeach Appโ€. Your benefits at a glance: 1. Mobile teach-in 2. Saves time 3. Easy to operate
