    CNC specialist NUM is helping Grupo Plasma Automation – one of Latin America’s top fabrication equipment manufacturers – to develop an innovative high speed laser cutting machine that uses real-time adaptive height control to accelerate throughput.

    Grupo Plasma Automation comprises eight companies that specialize in the design and manufacture of fabrication automation. The group produces a broad range of plasma, laser and water jet cutting machines. Founded in 1991, GPA has grown steadily over the years and has built up a large and prestigious customer base; it has more than 700 cutting systems installed at companies in Mexico alone, and nowadays serves both the domestic and international markets.

    GPA’s latest CNC laser cutting machine is designed to provide sheet metal fabricators with an ultra-flexible precision cutting solution. Branded SPEED CUT, the machine is capable of cutting a wide variety of metals with different densities, including galvanized iron, aluminum, brass, stainless and carbon steel. It has a work area of 1.5 x 3 meters and a maximum cutting speed of 120 meters per minute, with 40 microns positioning accuracy. The system delivers extremely smooth operation even at high speeds.

    To help maximize performance and reliability, GPA’s new cutting machine is based entirely on industry-leading laser and control technology. The laser source is a 2 kW IPG Photonics’ solid state ytterbium fiber system, with a wavelength of 1.07 micrometers, while the cutting head is a Precitec LightCutter 2.0 unit. This particular cutting head is renowned for its dynamic performance – it features automated motor-driven adjustment of the axial focus position, can handle acceleration rates as high as 3 g, and covers a large focus position range of 23 mm.

    All cutting head positioning functions on the machine are controlled by a NUM Flexium+ 8 CNC system. According to Omar Sandoval, Owner and CEO of GPA, “We chose to partner with NUM mainly because of its open architecture CNC platform and NUM’s willingness to actively participate in joint development projects such as this.”

    All four machine axes are driven by NUM high torque BPX servomotors controlled by NUMDrive X digital servo drives; the Y1 and Y2 gantry axes are equipped with powerful 9.8 Nm motors, while the X and Z axes have smaller 2.7 Nm and 1.4 Nm motors, respectively. NUM’s Flexium Tool commissioning software allows the Y1/Y2 axes to be tuned while the synchronization is active, which provides a very powerful means of maximizing performance and precision.

    The Z axis controls the vertical height of the laser cutting head above the sheet of metal that is being cut. By capitalizing on the unique ‘Dynamic Operator’ (DO) function in NUM’s Flexium software – which enables event-driven machine cycles to be integrated into the real-time CNC kernel – the user of the speed cut machine benefits from an automated dynamic height control system that accommodates extremely fast cutting speeds. The system interprets data from the machine’s cutting head height sensor and uses it to very quickly adjust proportional-integral-derivative (PID) loop parameters in the Z axis servo. The height sensor is also employed to facilitate an automatic sheet detection routine: this determines the workpiece’s dimensions, zero, and angular offset, further simplifying the machine’s operation.

    Steven Schilling, Managing Director of NUM Corporation in Naperville, Illinois, points out, “We are delighted to be collaborating with GPA in the development of this new machine. In addition to the real-time adaptive height control and sheet detection systems, the customized version of NUMcut software that we are providing features a user library of material cutting conditions. It is preloaded by GPA with the optimal laser power levels, cutting speeds, etc., as a function of material type and thickness. The provision of this library will further add to the machine’s productivity and cutting accuracy.”

  • 01/26/2021 – Teufen (AR), CH

    NUM has launched innovative artificial intelligence software that provides CNC machine tool users with highly cost-effective condition monitoring capabilities.

    Compatible with all of NUM’s latest-generation Flexium+ CNC systems, the NUMai software package is a complete, fully integrated solution for CNC machine tools – it does not require any additional sensors, and runs on the same industrial PC as the CNC system’s HMI (human-machine interface).

    NUMai software can be utilized as soon as a machine tool has been commissioned and is ready to start production, or on a machine that is already being employed for production purposes. The software initially acquires all pertinent operating data over a period of time, typically a number of hours, while the machine is being used for normal production tasks. Ideally, a diversity of part programs is run, involving a variety of different machining conditions, in order to ensure that the data is as comprehensive and reliable as possible.

  • 8/22/2019 – Teufen, AR (CH)

    NUM has launched an innovative accelerometer-based active vibration control system for CNC machine tools (see video below). Primarily designed to improve machining by virtually eliminating tool head vibration, the system further helps increase productivity by maximising material removal rate (MRR) and can also provide valuable real-time feedback for predictive maintenance purposes. 

    The system is available as a retrofittable option for any machine tool that uses NUM’s MDLUX high performance digital servo drives, which form part of the company’s Flexium+ CNC platform.

    NUM’s active vibration control system is a very cost-effective solution that provides unprecedented dynamic damping capabilities. Most competitive accelerometers on the market are only capable of low frequency sampling rates and require additional signal conditioning electronics before they can be connected – usually via Fieldbus – to the CNC or PLC system. Typically, acceleration data can only be retrieved once every 20 milliseconds, which is inadequate for vibration damping purposes on machine tools. The accelerometer in NUM’s new system is sampled every 100 microseconds, which means that it can be used for closed loop control at bandwidths approaching several hundreds of Hertz.

    The small flange-mounting accelerometer transducer can easily be attached to the machine’s tool head and has a sensitivity of 0.02 g (1.96 m/sec/sec), with a measurement range of plus/minus 2 g (plus/minus 19.6 m/sec/sec). The transducer connects directly to the digital servo drive, obviating the need for any additional signal conditioning circuitry.

    The active vibration control system utilises the drive embedded macros (DEM-X) option that is available on NUM’s MDLUX high performance digital servo drives. This option enables real-time macros to be embedded within the drive in order to manipulate its regulation algorithms. The output signal from the accelerometer transducer can thus be used to directly influence the behaviour of the speed servo control loop. All MDLUX servo drive modules use advanced DSP control techniques to maximise the CNC kernel-to-drive servo bus speed, and feature high loop bandwidths and special acceleration algorithms for uncompromised speed and positioning accuracy.

  • June 1, 2021 — Supertec Machinery Inc., one of Taiwan’s leading machine tool manufacturers, has chosen to base new versions of its renowned Plunge type of CNC cylindrical grinding machines on NUM’s Flexium+ CNC platform.

    Founded in 1954, Supertec Machinery Inc. has grown to become one of Taiwan’s top machine tool manufacturers. The company specialises in precision grinding automation and produces a diverse range of centreless, cylindrical and surface grinding machines. Based in Taichung City, Supertec operates sales and support facilities at strategic locations throughout Asia and Europe, as well as in the USA and South America.

    Supertec has traditionally used Fanuc CNC systems for most of its machine tools. However, when NUM added non-circular grinding functionality to its popular NUMgrind cylindrical grinding software back in June 2020, the company realised that this innovative CNC technology provided exactly what many of its customers needed on their cylindrical grinders.

    NUMgrind simplifies the creation of G code programs for CNC grinding machines through the use of a highly intuitive graphical human machine interface (HMI), and unlike conventional CAD/CAM workstation tools, it is designed specifically for use by shop floor personnel in a production environment.

    After evaluating the software, Supertec immediately raised a purchase contract with NUM. According to Betty Chu, Supertec’s Assistant General Manager, “NUM has an excellent reputation in the grinding industry. Much like Supertec, this has been earned over many years. And the latest version of NUMgrind, which accommodates non-circular grinding, is a natural fit for our CNC cylindrical grinding machines. We also now benefit from very responsive local support – NUM’s Taiwan facility is less than 15 km away from our factory.”

    Supertec’s Plunge type of CNC Cylindrical grinding machines offer a choice of six capacities, covering distances between centres from 500 mm to 2,000 mm. The machines can also accommodate grinding diameters from 300 up to 430 mm (3 sizes), grinding wheel speeds up to 1,390 rpm and workhead spindle speeds from 30 to 350 rpm.

    The new versions of these machines are based on NUM’s Flexium+ 8 CNC platform and use NUM’s high performance MDLUX drives and brushless servo motors for the X, Z and C axes. In addition to the NUMgrind HMI, the software that is being supplied by NUM includes the Flexium 3D simulator, which can be used offline or online, and an application-specific profile editor which enables users to import DXF files.

    Johnny Wu, General Manager for NUM Taiwan, points out, “The ability to use the Flexium 3D simulator both offline and online provides Supertec’s customers with a distinct advantage. CNC programs can obviously be prepared offline and checked for potential problems such as collisions before being transferred to the machine. But the simulator can also be used online. This enables operators to gain vital visibility of the grinding process – which is normally obscured by the flow of oil.”

    • Flexium+ builds on the success of NUM’s Flexium system to advance CNC to a new level. It combines all the power, flexibility and user-friend-liness NUM’s products are renowned for, with additional state of the art functionality and a completely new hardware and software platform.

    The outstanding success of Flexium with over 10,000 applications completed in a short space of time paved the way for development of Flexium+. We took the best components, kept those elements behind the success of our previous CNCs, such as scalability, flexibility, unique CNC functions, standardized interfaces and PLC programming, then renovated and improved the complete system. Flexium+ has new and enhanced features, new panels, a new HMI, an enhanced servo bus, enhanced drives and simplified connectivity – all within a completely new safety-related architecture.

    To provide optimum cost/performance ratios, Flexium+ exists in three configuration levels:

    • Flexium+ 6

    • Flexium+ 8

    • Flexium+ 68

    The compact dimensions of all components of the Flexium+ system are in line with NUM’s green approach regarding limited energy requirements, smaller cabinet dimensions, reduced power dissipation, and minimal weight and packaging, while assuring the best performance.

    Latest generation processors powering intelligent and evolutionary hardware ensure return on investment and a long system life, in line with NUM’s philosophy.

    Increased CNC functionality offers improved flexibility, scalability and accuracy. In particular, we have extended the concept of axis or spindle to allow control of up to 32 spindles per NCK unit (NCK for NC Kernel) and make spindle/ axis commutation even easier. We have also improved the internal computing resolution, increased the digital servo bus speed, and much more. The ability to link several NCKs together in a global configuration has of course been maintained, enabling, for example, the control of large transfer systems with more than 200 interpolating axes.

    Thanks to enhanced algorithms, the data are processed internally with a higher accuracy. This feature, named ‘Nano interpolation’, provides much more precise control of travel, speed and acceleration.

    The Flexium+ system encompasses the NUMDrive X digital drives controlled via up to three RJ45 ports, allowing for easily wired distributed drive sets on the machine. In addition to the digital links, two analog interfaces are provided for special requirements.

    The PLC itself complies with the IEC 61131-3 standard and communicates via efficient standardized interfaces like EtherCAT for fast exchanges, as well as providing the opportunity to build a safe machine environment in compliance with the standards EN 13849-1 up to PL e and EN61800-5-2 up to SIL 3.

    The human-machine interface is provided via PC panels, including a revolutionary 19” unit and companion machine panel, all running modern fully redesigned HMI software. There is a choice of machine panels and portable units, and the renowned Flexium 3D simulation package rounds out the portfolio.

  • NUMDriveX servo drives - Compact and Powerful
    The NUMDriveX servo drives with their modern design are the ideal counterpart to the powerful CNC control. Modular in design, compact in their dimensions and with a low power consumption, they are ideally matched to the needs of modern systems. ...
     

    • NUMDrive X

    The modern design of NUMDrive X servo drives makes them the ideal counterpart to the powerful Flexium+ CNC.

    One distinguishing feature of the NUMDrive X is its high power density. The servo drives offer an enormous amount of computing and drive power within a very small space and thus have one of the highest power/volume ratios available. A high degree of integration and efficiency has allowed us to achieve an extremely compact design that makes NUMDrive X one of the smallest high-end drives on the market. Thanks to a small depth and a modular width (a multiple of 50 mm) the cabinet layout is greatly simplified.

    The range is characterized by a wide choice of current from a few amperes up to 282 Arms, Bi-Axis versions are available up to 2x 53 Arms to enable each application to be optimized at the lowest cost. For the maximum contour precision, speeds and cost-effectiveness, the NUMDrive X servo drives can be exactly adapted to the particular machine and application.

    NUMDrive X is a modular system that is optimized for multi-axis applications. Use of a common power supply unit means that only one mains connec-tion, one line filter and one braking resistor are required per system, reducing cabling and overall costs. The system’s modularity also facilitates energy exchange between different axes via the DC bus, offers the possibility of using stored energy for retraction purposes, and – in the case of regenerative power supplies – allows energy to be re-injected into the mains to reduce machine operating cost. Such system conception also leads the way for a greener approach.

    NUMDrive X offers a choice of two performance levels:

    • Standard-Performance (SP) drives
    • High-Performance (HP) drives

    Featuring high internal resolution, a short sampling time and specially developed algorithms, the HP versions are designed for sophisticated and complex applications in precision machine tools. The position control loop is closed with a very high bandwidth, achieving exceptional precision and speed at the mechanical interface of the machine (motor axis, linear motor). NUMDrive X accepts almost all measuring systems and can control a broad range of motors (servo, torque, linear, asynchronous motors) from NUM or other manufacturers. This ensures that a solution can be optimized from the technical and economic perspectives.

    The HP versions of NUMDrive X also incorporate unique functionality known as DEMX (Drive Embedded Macro). This allows users to create their own real-time macro which can interact with all physical and virtual drive resources – even to the extent of manipulating the regulation algorithms. Users can design and implement filters and monitors, define test points and create pilot outputs that obey user-stipulated rules.

    The SP versions of NUMDrive X are suited to systems and precision machine tools of medium complexity, as well as cost-sensitive applications.

    Within the NUMSafe architecture, NUMDrive X provides the safe motion functionalities by means of two different modules:

    • NUM-STOX is the basic module for implementing the Safe Torque Off function certified up to SIL 3 according to IEC 61508. This allows the realization of E-STOP functions category 0 and 1 according to EN60204-1
    • NUM-SAMX is the extended functionality module which provides a huge number of safe motion monitoring functions. STO Safe Torque Off, SLS Safely Limited Speed, SOS Safe Operational Stop, SS1 Safe Stop 1, SS2 Safe Stop 2, SLP Safe Limited Position, SDM (Safe Direction Monitoring) and SCA Safe CAMs

  • + CNC Function - Early Block Change - for Cutting
    NUM’s new firmware feature named Early Block Change (EBC), G-code G777, gives the user the ability to begin execution of the next block of code while the current block is still executing. Very useful water-jet, laser or plasma cutting!...
     

    • Early Bock Change (EBC) allows the system to start the execution of the next NC block before the current block has completed its execution. This allows for faster machining cycle times and the ability to execute asynchronous movements within the part-program.

    Overview
    NUM’s new firmware feature named Early Block Change (EBC), G-code G777, gives the user the ability to begin execution of the next block of code while the current block is still executing. This allows the machine to be performing two blocks of machine motion at one time. This feature gives users the ability to dramatically speed up production cycles in many different industries.

    The EBC function also provides a very fast signal exchange between the PLC and the part program, allowing the PLC to control machine motion and get information about program execution using 32 dedicated input and 32 dedicated output bits.

    Furthermore, the NCK communicates to the PLC when certain conditions in the program execution have been reached, allowing the PLC to start auxiliary operations without the need to program M functions – and thus without stopping any axis motion. All of these features are easily programmed with a single G function and a few parameters.
