Fragmentation rate

Due to the high absorption in water of 1.94 µm wavelength and superpulse mode, the rate of fragmentation of concrements in "Dust" mode is twice as fast as that of holmium lasers4.

Minimal retropulsion

When comparing the effect of retropulsion in holmium lasers and superpulsed thulium fiber laser, it was proved that the TFL allows complete elimination of stone migration5.

Multi-Axis Workstation Software

The Multi-Axis family of workstations are high-accuracy platforms designed to take advantage of the high beam quality found in IPG’s fiber lasers. Systems can be configured using any IPG laser, with laser processing heads available for welding, cutting and scanning applications. System options can include both basic and smart vision packages, along with part identification and process verification hardware.

The Multi-Axis software integrates control of the laser, motion systems and all system components to provide easy programming of the tool using G/M code commands that are familiar to CNC machine programmers.

HMI (Human Machine Interface)

The software that runs the Multi-Axis Workstations is a customized application called HMI (Human Machine Interface) that runs as a Microsoft Windows® 7 application. It is preloaded and tested at the IPG factory and resides in the workstation’s hard drive.

The HMI program consists of four primary regions:

  • System Status Indicators – Providing a constant overview of the machine status, regardless of function selected
  • Function Selection Bar – Providing primary selection of module operation
  • Function Control Interface – Allows intuitive set up of configuration and operating parameters
  • Manual Control Bar – Enabling manual operation of the systems global functions

Three Password-Protected Levels of System Control: Engineer, Maintenance and Operator.

User screens enable the Engineer, acting as system administrator, to easily set permission levels for each HMI screen for each level of operator and set corresponding passwords.

The system can operate in manual or programmed mode, and has functions to enable Dry-Run (execution of the full program but with the laser not turned on) and Optional Stop – that will allow a pause in the processing cycle for part inspection and other uses.

Used in combination with standard G-code programming, these capabilities provide the user with a comprehensive, easy-to-use programming and operator interface.
