What is a roboTest P?

The roboTest P is a fully automatic test system for tensile tests on metals. Depending on the specimen dimensions and specimen surface, up to 300 specimens can be tested autonomously.

The operator fills the specimen magazine in the safe area of the system, which also makes it possible to fill the magazine while the test is running.

After starting the system, specimen feeding, testing and removal of the specimen remains occur automatically. The specimen test sequence can be specified by the operator at anytime. Disposal of the specimen remains with good/bad sorting is made possible through appropriate tolerance criteria.

The specimen throughput can be optimally adapted to customer requirements with the use of additional devices, such as a cross-section measuring device, ID scanner, roughness measuring device or hardness tester. Determination of the r-value or reduction of area is also carried out with accuracy and repeatability in the automatic sequence.

To increase specimen throughput, multiple materials testing machines can be tied into the system.

For manual tests, the specimen gripper can be moved to the side, making the materials testing machine accessible to the operator. For systems with two testing machines, an additional safety area allows an operator to run manual tests in parallel with automatic operation.

Number of specimens

Up to 300 identical or similar specimens

Test load

Up to 2,500 kN

Complexity

Complex test tasks; multiple devices and components

Robotic testing system for heavy plates

Robotic testing system roboTest P with 1200 kN testing machine for tensile tests on heavy plate. Before the test, both the cross-section and the length of the specimen are measured automatically.

Advantages

Operator influences (hand temperature/moisture, off-center or angled specimen insertion etc.) are eliminated resulting in high test-result reproducibility.
Qualified laboratory staff are relieved of routine activities, allowing them to focus on more complex tasks.
The machine can be used during idle times (lunch breaks and night shifts), which increases the full capacity and produces faster results.
The testing system reduces the testing costs per specimen and typically pays for itself within one to two years.
The system supports reliable documentation and statistical long-term monitoring.

Components and accessories

Feeding

The feed axis automatically and safely transports specimens up to 10 kg. For manual tests, the specimen gripper can be driven to the side, making the materials testing machine accessible to the operator.

Shelf magazine for flat specimens 2000 kN

Specimen magazine

The magazine holds up to 400 specimens, depending on specimen dimensions. The operator fills the specimen magazine in the safe area of the system. Filling can also be performed in test mode.

Measurement of the specimen cross-section

The automated cross-section measurement for determining the specimen thickness and width is taken at one or three points on the specimen. Use of a standard allows the cross-section measuring device to be adjusted, ensuring reproducible test results.

The specimen's surface roughness is measured in the automated sequence

Surface roughness measurement

In addition, the surface roughness can be determined by using an optional roughness measuring device.

Measurement of reduction in area

Two cameras record the specimen during the test. After break, the software aligns the two specimen halves and joins them together.

The bar code or 2D code is read during the automated sequence

ID reader

Use of an optional barcode or 2D code reader eliminates errors in specimen identification. Alternatively, the specimen data (identification number, width, thickness, etc.) can be entered on a PC.

Determining the r-value with the use of a transverse strain extensometer

r-value determination

The measurement of the change in width compared to the initial width (tensile test on metals) is performed using a sensor arm or optical extensometer.

Hardness measurement

A hardness measuring device can be optionally integrated into the robotic testing system.
