Investing in the future of 3D measurement

5-axis REVO® or PH20 technology

Differences between three-axis and five-axis measurements:

Three-axis measurement

• All 3 axes for machine movement are involved in the measurement
• Measurement and scanning accuracy are not affected at low speeds
• The dynamic effects of the machine cause greater measurement uncertainty
• The mechanical construction of the machine has a great influence on the resulting accuracy

Five-axis measurement:

• The mechanical and dynamic effects of the machine are eliminated by the movement of the five-axis REVO or PH20 system
• During the sensing itself, the movements of the REVO or PH20 head and the measuring machine are combined
• A very high measurement and scanning speed is achieved without affecting accuracy
• The REVO system uses laser interferometry technology

The main advantages of modernization to a five-axis system

The main advantages of upgrading an existing measuring machine include the versatility of Renishaw systems from its UCC (I ++) control to software variability. Renishaw five-axis systems can use a range of software that we offer: and fully support.

• TouchDMIS software for measuring with the PH20 system
• Polyworks Inspector software for REVO and PH20 systems
• MODUS software for REVO and PH20 systems

Important factors in the modernization of an older measuring machine are the creation of a new correction map of the machine and the actual correction map of the REVO or PH20 sensor head. These features guarantee high accuracy and efficiency even of older models of measuring machines.

Advantages of the five-axis system:

• Much less time required to position the head and change the stylus
• Improved CMM functions: better availability of measured elements and better measurement methods
• Reduction of measurement time by up to 70%
• More measured data in a very short time
• The REVO system enables the use of various sensors and transducers for the needs of touch scanning, roughness measurement or camera scanning

Examples of applications for the REVO system

Measurement and scanning of automotive components

• Significant savings in measurement and scanning time
• Measurement of gearboxes, valves, cylinder heads
• Detailed information about each measured element
• Easy and fast tool change in the automatic exchanger without the need for calibration

Blade measurement in the aerospace and energy industries

• With the help of scanning, you will ensure inspection in countless sections of blades and turbines
• Analysis of the entire area from highly accurately scanned data
• Detection and evaluation of points on the trailing edge of the blade

Sensor variability, flexible tool change and short calibration time

REVO system sensors

The REVO system offers the most common sensing options with one measuring head. With the REVO head, you can use sensors and tools for 2D / 3D surface scanning, five-axis point measurement, non-contact measurement and surface roughness measurement. The automatic exchanger of probes and tools for REVO significantly saves space on the measuring machine.

Possibility to use direct styluses for point measurement and scanning up to 800 mm and angular styluses up to 600 mm with RSP3 probe. Surface roughness measurement allows complete inspection of parts on one measuring device. This saves measurement time as well as workspace in production areas.

Calibration of probes and tools

With the five-axis REVO and PH20 systems, you significantly save time calibrating the probes and tools you use for measuring tasks. Calibration, as well as the measurement itself, takes place by means of motorized head movements. If a coordinate measuring machine is used to measure multiple characteristics, it can typically have 40 head orientations, which dramatically increases the calibration time to approximately 2 hours. With five-axis technology, the whole process takes only 20 minutes.

Use of PH20 system

The PH20 touch sensing system is advantageous for applications where you are looking for significant time savings when measuring in touch mode. These are typically applications where mass-produced parts that have a fragmented character are measured. Typically, this is a dimensional inspection of components in the automotive, aerospace or precision shop industries.

The PH20's unique "head touches" allow measuring points to be read by simply moving the head and not the entire frame of the measuring machine. Points can be scanned faster, with higher accuracy and repeatability. In addition, the five-axis motion eliminates the time required to index the head. At the same time, this increase in speed usually increases performance by up to three times compared to conventional three-axis systems.

TP20 integrated probe

PH20 users have the opportunity to use a range of proven TP20 replacement modules. These modules offer a wide selection of switching forces and extended measurement range. Interchangeable modules provide collision protection and can be replaced automatically using the TCR20 automatic magazine.
