The latest generation of TruDisk lasers from Trumpf offers built-in intelligence to perform condition monitoring, predictive maintenance and trend analysis, all of which support the implementation of lasers in digital and connected manufacturing environments.

At the hub of the TruDisk beam source is the built-in control system known as CPX. This is the laser’s brain, where all of the condition data and process parameters are collected. During processing, sensors measure multiple parameters, including the actual laser output at microsecond intervals, all internal and external signal characteristics, the utilisation rate of the beam source, and the condition of additional components.
TruDisk lasers also incorporate a new feature that enhances the quality of data obtained from the readings. Known as ‘precision time protocol’, the feature synchronises the sensors and provides them with an identical time stamp.
The new lasers can be combined with Trumpf’s condition-based services (modular components of TruConnect, the company’s technology for connected manufacturing), which increase the availability and productivity of connected systems while identifying potential cost savings. With the customer’s prior approval, the services can be used to analyse data parameters, carry out algorithm-based trend analysis and take targeted measures to determine the risk of potential laser failure in advance.
Another improvement can be found in the new Trumpf laser diodes, which are energy efficient to help minimise running costs. Furthermore, Trumpf has equipped the latest TruDisk lasers with a pulse function that makes it possible to ramp the current of the pump diodes down to 0 A.
The new generation of TruDisk laser is available for laser output of between 3 and 5 kW, with fibre core diameters between 100 and 600 µm.

Esab has unveiled SmartBevel technology for easier automated plasma programming and bevel cutting with minimal operator intervention. The system includes the data and geometric compensations necessary to cut V, X, Y and K bevels on mild steel from 6 to 50 mm thick. Esab says that unlike competitor systems, SmartBevel integrates all bevel compensations into the CNC to simplify bevel programming and enable operators to quickly fine-tune the program at the machine.

A number of plasma bevelling systems are under-utilised because of programming issues. SmartBevel integrates plasma, CNC, software, height control, bevel head and gantry functions so that users can take full advantage of their plasma-cutting system and maximise productivity.
Many bevelling technologies require programmers to compensate for torch angle, torch height, kerf width and cutting speed in the part program or nest. As a result, operators are prevented from making any adjustments that might be required to produce accurate parts. To make modifications, the operator must go back to the programmer and have the program or nest updated. This can waste time and present an obstacle to producing quality components.
Esab’s SmartBevel improves bevel cutting in two ways. First, the technology delivers more bevel data for more bevel geometries. A high level of automation is offered for the programmer by incorporating best practice bevel cut sequences into Esab’s Columbus III CADCAM programming and nesting software. Second, SmartBevel puts all bevel compensation data into the CNC, not the programming software. Therefore, the part program or nest represents the actual desired part geometry, without bevel compensations. This capability eliminates the need for trial-and-error programming. Instead, operators can quickly make any necessary adjustments at the machine.
