The people missing in the industry are being replaced by investments in automation

The domestic industry has been getting busy in recent years. It has to deal with a lack of components, materials and professional staff. While pandemic-disrupted supply chains make it difficult to replace companies, staff shortages are being addressed by investing in automation. The company recorded this key trend Re­nishaw at this year’s industrial fairs in Milan and Brno. The emphasis on industrial automation is evident worldwide.

In Czech conditions, it takes place not by a complete replacement of machines, but rather by an upgrade of existing production technologies. The goal of these upgrades is to ensure that more people can produce more or at least the same. The trend is also to simplify technologically demanding tasks so that even a short-trained worker can handle them.

The greatest interest is in innovative scanning systems with which the machines can be retrofitted and modernized. This makes it easy to automate the entire production process from workpiece setup through machining to inspection measurements.

For example, there is great interest in a non-contact laser tool probe NC4 s modrým laseremwhich provides much more accurate measurements than conventional touch probes. It gives machine tools the precision and, in conjunction with a computer, the intelligence needed for unattended production operations.

Renishaw NC4 NC4 non-contact tool probes provide highly fast and accurate tool measurement and damage detection; they allow process control on machine tools of all sizes and types. Blue laser technology achieves even more accurate measurements thanks to its shorter wavelength.

The lack of qualified experts is also positively reflected in the simplification of machine operation. The NC4 probe can also be programmed with jed­no­du­ché mo­bil­ní apli­ka­ce.

Ultrasound makes the production of supersonic aircraft cheaper

Ultrasonic probes are a new technology that streamlines production and saves time for professional staff. These include, for example ultrazvuková probe RUP1, which expands the possibilities of five-axis coordinate measuring machines. Automatic part thickness detection using ultrasound allows the measurement of very large parts or hard-to-reach elements.

Renishaw RUP1-2147 The RUP1 ultrasonic probe does not need a water tank or a connecting gel to transmit the signal. Instead, it has an innovative ball with an elastomeric tip, which ensures an excellent connection between the probe and the material.

At the EMO trade fair in Milan, the possibilities of the RUP1 probe were demonstrated when measuring the large landing gear leg of a supersonic aircraft, the cavity of which is very difficult to measure by other methods.

The advantage of the new generation of ultrasonic systems is the fact that they do not need a water tank or a connecting gel to transmit the signal. They have an innovative ball with an elastomeric tip, which ensures an excellent connection between the probe and the material. Therefore, the operator does not have to watch the oscilloscope screen, but instead does more important work.

A super-fast scale that the operator will never see

Another common upgrade is investing in modern ones od­mě­řo­va­cích pra­ví­tek. They move inside the machines faster than ferrari. They can repeatedly distinguish the position of the sensor with an accuracy of one nanometer, at a speed of up to 100 m / s! It’s like measuring the size of a molecule at 360 km / h.

Renishaw Fortis-2147
The Fortis measuring ruler consists only of an optical position sensor – a high-speed camera, which is located in a closed reading head. It scans a steel ruler with a so-called absolute scale, which has a fine spacing of 30 μm.

Although the rulers must measure very accurately, they are used in industry in a very inhospitable environment, where they resist the penetration of coolants, dust, chips. In addition, rulers are expected to measure accurately for years without the need for regular service. They are usually hidden deep inside the machine and only exceptionally are they removed from the inside.

Therefore, modern optical position sensors are designed similarly to the technologies used for space mining, ie as extremely durable and reliable, so that they never have to be removed. Therefore, most machine tool users have never seen a measuring ruler with their own eyes.

Clamping of parts using chewing gum is no longer necessary

Clamping systems have also undergone innovations, again in an effort to simplify the fastening of the measured part. In practice, this is a lengthy and unpleasant task. It is very difficult to fix the part so that it does not move and it is possible to measure all its elements. It requires considerable expertise, which is lacking.

Renishaw Quickload rail-2147 QuickLoad rail system is a smart solution for easy and variable clamping of parts on coordinate measuring machines. It simplifies the insertion of parts, speeds up the preparation for measurement and reduces the demands on the operator of the measuring machine.

Industrial companies are therefore interested in systems such as Quic­kLo­ad rail system, which is a smart solution for easy and variable clamping of parts on coordinate measuring machines. The clamping plates are fixed to special rails using quick-release magnets and positioning pins. When measuring, clamped assemblies can be exchanged literally in seconds. This makes it easy to mount and then measure any component.

This can significantly increase production capacity, repeatability and accuracy of the control process. This is a fundamental difference from fixing components with carpet tape or various adhesives, which are primitive but functional practices that still often occur in practice.
