Enhancing productivity and energy efficiency in machine tools

IndraMotion MTX CNC platform

Equipped with a multi-core processor, the IndraMotion MTX CNC platform executes programs at top speed, boosting machine productivity

IndraMotion MTX CNC solution from Rexroth now has multi-core processor and additional software functions

Enhancing productivity while reducing energy consumption – it’s not a contradiction in terms. The IndraMotion MTX CNC solution from Rexroth helps machine manufacturers and operators to balance these two key requirements and achieve both in optimum style. To do so, the drive and control specialist Rexroth has introduced a number of innovations in the hardware and software used for the system, which is now in its 12th version. Control units equipped with a multi-core processor execute programs at top speed, boosting productivity. The energy monitoring function of the software records energy consumption, either by specific consumers such as drive axes or by work piece, facilitating energy efficiency in machine tool operation.

The IndraMotion MTX CNC solution with integrated PLC is scalable in terms of functionality and productivity: Depending on the number of axes, users can choose between micro, standard, performance, and advanced.

The IndraMotion MTX advanced, which is equipped with a multi-core processor, was designed especially for machines with many axes and complex production processes that utilize multiple production technologies in a single work piece clamping. Intelligent distribution of control sequences to the multi-core architecture delivers the added performance necessary to execute programs quickly. The control system reaches a CNC interpolation time that ranges from 0.25 ms to 1 ms, which decreases auxiliary process times and enhances productivity.

Energy monitoring makes consumption transparent

With the energy monitoring function, operators can document the energy consumption of individual consumers such as drive axes or ancillary units for hydraulics and cooling lubricants, but it is also possible to determine energy consumption per work piece. When changes are made to the work piece material, when the tools show wear and tear, or when the auxiliary substances or lubricants are changed, this feature then allows for comparisons based on trending diagrams, making energy consumption transparent. Intelligent standby functions also make it possible to successively shut down those parts that require the most energy, for example until raw parts are available again.

Universal ‘run from’ function and new processing cycles

When large machining programs are interrupted, it is important to operators to ensure that processing can be continued precisely from where it was interrupted. The new universal ‘run from’ function of the IndraMotion MTX allows just that, by guiding the operator through the restart of the processing program. Detailed diagnoses show the machine operator where it is necessary to adjust the current machine status to the target status that is necessary to continue the program.

New processing cycles for milling allow operators to determine, based on simple criteria, whether the focus should be the processing time or the processing quality of a work piece. The rough machining of a work piece can thus be done very quickly, while the machine tool performs the subsequent precision machining with greater precision.

The latest version of IndraMotion MTX is equipped with an Ethernet field bus interface for multi-protocol operation, so manufacturers can choose between PROFINET and Ethernet/IP. Depending on the specific system configuration, sercos, PROFIBUS, PROFINET, or Ethernet/IP can be used to exchange data on the sensor-actuator level. The communication with the drive level is carried out via a sercos interface; the major advantage of this approach is that users can combine electrical and hydraulic servo drives.
