This high level of accuracy means that what you see throughout the simulation is almost precisely what you will get. Because the simulation is so accurate, there is no need for additional adjustments once the cobot is deployed, saving time and ensuring that implementation is both precise and efficient.

The Ultra Accuracy feature is an optional upgrade that can be integrated into existing GoFa cobots, enhancing their precision and performance.

Schmalz introduced two of its latest CNC wood processing vacuum blocks with a time-saving grid-to-nesting table-switching capability.

The automation solutions expert Schmalz announced the release of two innovative vacuum blocks, the VCBL-R and VCBL-N, for grid and nesting-based computer numerical control (CNC) wood processing applications. Depending on the desired use case, both vacuum blocks can be used interchangeably between grid and nesting tables. Adding or removing a nesting insert reduces time and manual labor when switching between applications. The flexibility offered by this functionality is intended to save woodworkers valuable time, reduce material waste, and improve production.


According to Schmalz, the laborious and time-consuming task of modifying setups when switching from grid tables to nesting tables during CNC wood processing is over. Image used courtesy of Schmalz

Switching from Grid Mode to Nesting Tables

Over the last twenty years, there has been a significant advancement in CNC wood processing in terms of automation, accuracy, and productivity. Modern CNC machines are outfitted with advanced software for automating toolpath planning and execution, integrating with CAD/CAM systems (Computer-Aided Design/Computer-Aided Manufacturing), performing multi-axis operations, and optimizing design-to-production processes.

In contrast to earlier systems, which mainly relied on manual setup and calibration, today's CNC machines are highly automated. Technological advancements like multipurpose vacuum tables, interchangeable suction systems, and intelligent sensors have significantly reduced setup times, improved adaptability, and facilitated faster project changes.

The key draw of Schmalz’s upgraded vacuum block series is the ability to switch from grid to nesting table via adding or removing a nesting insert. Tedious manual intervention must be performed to switch between suction cup-based grid clamping and sheet-vacuuming nesting fastening. To maintain pressure, technicians have to remove and reinstall suction cups when transferring between processes, position them for particular product layouts, and seal any unneeded vacuum zones. The complexity and time needed for setup modifications may increase if the CNC machine needs to be reset due to variations in elevation and flatness between grid and nested setups.

Using vacuum blocks that can fluidly transition between grid and nesting tables can increase productivity by minimizing the need for human interaction. Operators can transition between grid fastening and nesting more rapidly because of these blocks' quick repositioning and adjustment capabilities, eliminating the requirement for complete removal and reconfiguration. These blocks simplify setup, remove the need to seal unneeded zones, and reduce downtime by automating vacuum zone control and sustaining suction in all necessary places. As a result, the process becomes more effective, enabling faster transitions and increased throughput for CNC operations.
 
Features and Benefits

First in the lineup is the VCBL-R, designed to accommodate grid-based CNC wood applications and nesting table-based applications via an optional nesting insert. This insert allows customers to adhere the suction cup to the nesting plate. This flexible tool is ideal for conventional grid setups with dimensions 30 and 40 mm, groove widths between 6 to 7.5 mm, and groove depths of 6 to 7 mm.

Along with the VCBL-N, the VCBL-R features height (25 to 132 mm) and dimensional flexibility to suit specific workpiece requirements and an optional accessory hose connection for grid table positioning, even if the suction cup is without a suction point. Both vacuum blocks are designed for 3-axis and more intricate 5-axis machining.

The VCBL-R and VCBL-N incorporate a membrane covering the suction plate to protect from the ingress of dirt, ensure maximal frictional forces, optimal sealing, and improved workpiece protection.

The VCBL-N accommodates working heights between 32 to 132 mm and, like the VCBL-R, facilitates sensitive unloading and loading of heavy, extensive parts via an optional lifting system. This system also helps to protect the suction plate’s sealing edge from wear and tear.

IDEC has recently unveiled its newest Programmable Logic Controller (PLC) with a built-in Human Machine Interface (HMI), boasting several I/O ports and a 16 million color 4.3” display.

The FTIJ PLC+HMI is one of the easiest HMIs to read and interface. It combines a capable controller with a brilliant HMI and will likely be used in many industrial and manufacturing settings. By combining the PLC and the HMI into one unit, IDEC has beefed up its processing capability to ensure quick calculations and decisions are made. The FTIJ PLC+HMI has dual CPUs, one for the PLC and one for the HMI. This keeps tasks organized, providing a degree of separation between user inputs and displays in the HMI from the process control occurring in the PLC while still integrating these systems.

Features of the FTIJ PLC+HMI

Regarding connectivity, the FTIJ PLC+HMI has eight built-in DC I/O ports, configurable as discrete or up to two 4-20 mA analog channels. Each channel can be scanned at up to 20 kHz, meaning data can be collected quickly, and short-lived events can be captured. Two-wire RTD and thermocouple measurements can be made with this device as well. All channels have 12-bit resolution.

Data can be transferred using several common industrial protocols, including MQTT, EtherNet/IP, Modbus, and many others. Furthermore, data can be directly ported to email or Twitter/X, though care must be taken to preserve trade secrets and data not meant for the public.

Perhaps the most impressive feature of this device is its display. With 16 million colors, the 4.3” (480x272 pixel) display is bright and readable in virtually all lighting conditions. The display is a capacitive touchscreen that can be operated even with gloved fingers. It has fewer touch screen layers, meaning less light loss through the touch screen, yet maintains its responsiveness.


The PLC+HMI can expand its I/O ports by adding I/O cartridges. Image used courtesy of IDEC

The integrated PLC+HMI can also add I/O cartridges, expanding the total number by up to eight digital or four analog I/O ports. With up to 22 total I/O ports, the device delivers the connectivity needed to operate.
 
Advantages of an Integrated PLC and HMI

In edge computing, the idea is to separate tasks, divide them among devices, and move them to the “edges” of the network. However, there are some cases where integrating a few essential components provides advantages.

In the case of the IDEC FTIJ PLC+HMI, integrating the PLC and HMI together reduces the system's complexity and installation at a few key points. It also takes up less room in instrumentation cabinets, as both devices are combined into one package.

This controller is not meant to replace every single PLC in an edge computing-capable automation system but rather to replace frequently used components or components that benefit from a local HMI for local control and display of process parameters.

The IDEC FTIJ PLC+HMI will likely see plenty of use in large manufacturing facilities with many machines, process monitors, etc. It may also catch on with machine builders as a controller and interface for single pieces of equipment.

Tolomatic has introduced five new RSX high-force electric linear actuators to meet a broader range of applications. These high-force actuators may be a better option than traditional hydraulics.

Tolomatic’s addition of five new linear actuators attempts to persuade traditionalists to switch from hydraulic to electric systems. These linear actuators include forces of up to 66,000 lbf (294 kN) and have some advantages over hydraulic systems. Let’s explore the capabilities, specs, and benefits of electric over hydraulic systems.


This image clarifies Tolomatic’s RSX actuators' force capabilities, which forms the argument for replacing traditional hydraulic systems. Image used courtesy of Tolomatic

RSX Electric Linear Actuator Spotlight

Although the primary selling point of the newly introduced RSX Electric Linear Actuators is their high-force capabilities, they also have many other specifications that may persuade users to make the switch.

The RSX linear actuators are designed to provide cleanliness and durability. They have an IP67 option to protect against dust and water and a food-grade design option. Users can feel confident that these actuators meet standards for various industries. Additionally, these actuators feature a heavy-duty internal bumper that protects moving components at both ends of the stroke, where wear and tear are commonly compounded. They also have high positional accuracy, with the roller nut capable of ±0.0102mm/300mm and the ball nut ±0.102mm/300mm.
 
Multiple Options Available

These actuators are available in ball and planetary roller screw-driven designs. These options allow users to decide which actuator best suits their needs. The deciding factors depend on the user's requirements, such as power density, linear velocity, life expectancy, accuracy and repeatability, and relative cost. Roller screw designs allow for more power density because of the extension of contact points, allowing the load to be distributed more evenly.

Ball screws have lower power density and life expectancy but offer increased efficiency in high-speed applications, with a 90% efficiency rating. In contrast, roller screws have an 80% efficiency rating. Whether users lack accuracy needs but require power density or prefer the most life expectancy, Tolotmatic actuators suit application needs.

Tolomatic offers a super-duty option known as the RSX096 oil-cooled option. This option suits applications that need higher duty cycles and power than traditional grease and lubrication designs can handle. The oil-cooled option design efficiently transfers heat throughout the moving components of the cylinder, allowing it to handle a 100% duty cycle while also providing a long life expectancy. It's the best of both worlds.

Electric Vs. Hydraulic Actuators

When choosing between hydraulic and electric actuators, several factors must be considered to ensure the best fit for your application.

Hydraulic actuators can produce high forces and speeds, making them suitable for heavy-duty applications, but they may not offer the same level of precision as electric actuators. Electric actuators provide better precision and control, making them ideal for applications requiring accurate positioning.

They also require less maintenance and eliminate the risk of fluid leaks, making them cleaner and more environmentally friendly. Additionally, electric actuators are suitable for a wide range of environments, including extreme temperatures and cleanroom settings. They are typically more energy-efficient as they convert electrical energy directly into mechanical motion.

Electric actuators generally have a higher initial cost but lower operating and maintenance costs in the long term. In contrast, hydraulic actuators, though often used in harsh environments, can be affected by temperature changes and require robust sealing, leading to higher long-term maintenance and operational costs. These factors will help you determine the best actuator type for your needs.

Siemens also makes it easy to use only the features that are required. Control functions are available for subscription use, meaning engineers can select which functions are necessary for their particular facility’s needs and only pay for those. In the long run, this saves money and complexity, as they are not paying for bloated software packages with functionality that is neither necessary nor appreciated. As a subscription model, software upgrades are readily available versus having to retire legacy software and purchase new software throughout the life of the physical MCC.
 
Communication with SIMOCODE M-CP

Communication is made possible through Single Pair Ethernet (SPE). These wired connections are secure and reliable and have already been used in many industrial facilities. Furthermore, SPE requires only two cables, drastically simplifying setup, configuration, and troubleshooting efforts.
 
Motor Control Signature Analysis

Built into the MCC are tools such as the Motor Current Signature Analysis (MCSA), which can evaluate the current flow of four motors and adjust power as needed. This MCSA works from an energy efficiency standpoint, optimizing the load between motors, and from a safety standpoint, looking for unusual load conditions from a safety standpoint.

The MCSA can be used to highlight trends and schedule preventative maintenance. For example, suppose the current of one motor slowly increases over time. This could mean that the bearings are worn and should be replaced or that the motor needs to be thoroughly cleaned.
 
Targeted Applications

Siemens has produced automation hardware and software that serves virtually every industrial and manufacturing market. The SIMOCODE M-CP will also be suitable for almost every industry and will be used in many different fields. Due to its ease of installation and compact size, it will serve both space-limited small manufacturing facilities and heavy industry alike–there is a lot to appreciate with this small MCC. Chemical processing, steel, construction (such as tunnel boring), pharmaceuticals, and many other industries will benefit from the small footprint and processing capabilities made possible by the SIMOCODE M-CP.
