How to achieve a 3-fold increase in your CMM Performance

Users of all brands of CMM now have the opportunity to transform their measurement performance with an upgrade to Renishaw’s innovative metrology systems.

You don’t need to change your measuring system, simply change the way it works and transform your outdated equipment into a valuable asset and discover the hidden power of your CMM.

Measurement is vital to any manufacturing business, providing essential information to control processes and verify products. But older co-ordinate measuring machines (CMMs) can become bottlenecks if they fail to keep pace with changing measurement needs. Advances in sensor, metrology software and controller technology now offer the opportunity to transform existing CMMs, providing greater accuracy, faster measurement, more automation and new capabilities, whilst taking full advantage of CAD-driven programming, therefore upgrading makes good economic and ecological sense.

Get more from your CMM

The most advanced technology developments in sensors, controllers and metrology software have transformed the performance of new CMMs. As these advances are not dependent on the CMM frame, they are also available on your old CMM, resulting in:

  • More capability with simple, fast and intuitive CAD-driven programming and graphical reports that are easier to interpret
  • More throughput using the latest scanning sensors and motion control technologies
  • More information about your parts with automated multisensor measurement
  • More profitability with reduced maintenance and support costs
  • More confidence that your CMM is equipped to meet your future measurement needs

Most CMM structures are not subject to high levels of wear and so remain serviceable for many years. What’s more, because you are re-using the costly superstructure of the machine, an upgrade is a fraction of the price of a comparable new machine.

  • Measure without compromise by using radically shorter cycle times to enable 100% inspection for optimum verification and process control

The operational benefits this brings are as follows:

  • Reduced measurement cycle times
  • Elimination of CMM bottlenecks and rapid process feedback
  • High speed head and sensor calibration increases uptime
  • Less time spent indexing and stylus changing, resulting in more time spent measuring

3-axis and 5-axis Measurement

Let’s look at how probing technology has evolved and highlight the differences between 3 and 5 axis measurement.

3-axis measurement and 5-axis measurement refer to the number of axes or directions in which a measuring device can move. These terms are commonly used in the context of CMM’S used for precise dimensional measurement of objects.

3-axis Measurement

A 3-axis measurement system can move in three orthogonal directions, typically represented as the X, Y, and Z axes. This means that the measuring probe or sensor can move forward and backward (X-axis), left and right (Y-axis), and up and down (Z-axis). The 3-axis CMM can measure length, width, and height, making it suitable for many standard measurement tasks, although there are some limitations with 3-Axis fixed Probing compared to 5-axis measurement:

  • Speed of Measurement
  • Fixturing Costs
  • Calibration time
  • Tooling Costs
  • Feature Access

5-axis Measurement

A 5-axis measurement system, also known as a multi-axis CMM, can move in five different directions. In addition to the X, Y, and Z axes, it can also rotate around two additional axes, typically referred to as the A and B axes. The A-axis is a rotation around the X-axis, while the B-axis is a rotation around the Y-axis. This additional rotational capability allows the probe to reach complex angles and orientations, enabling the measurement of more intricate geometries, freeform surfaces, and features that are difficult to access with a 3-axis system.

The main difference between 3-axis and 5-axis measurement is the level of flexibility and freedom of movement offered by the additional two rotational axes in the 5-axis system. The 5-axis measurement capability provides enhanced versatility and allows for more comprehensive and accurate measurement of complex shapes and contours. It is particularly useful in industries such as aerospace, automotive, tool and die, and medical, where precise measurement of intricate components is required.

It’s also important to note that the number of axes is not the sole factor determining the accuracy or capabilities of a measurement system. Other factors such as the quality of the measuring probe, the software used for data analysis, and the overall system design also play significant roles in achieving accurate and reliable measurements.

PH20 5-axis touch-trigger system

Unlike conventional touch-trigger measurement methods which rely on speeding up the motion of the CMM’s 3 axes to measure quickly, PH20 utilises the head motion technology developed for the multi-award winning REVO system to minimise the dynamic errors of the CMM at higher measurement speeds.

PH20’s unique ‘head touches’ allow measurement points to be taken by moving only the head, rather than the CMM structure. Points can be taken faster, and with improved accuracy and repeatability.

Furthermore, 5-axis motion eliminates time spent indexing the head. Together these speed increases typically result in a 3-fold improvement in throughput over conventional systems.

Easy access to features at any angle

PH20’s infinite positioning capability guarantees optimal feature access, minimising stylus changes. The 5-axis simultaneous motion allows larger parts to be measured on the CMM by minimising the space required around the part for head rotation. PH20 automatically aligns itself with the part co-ordinate system, avoiding stylus collisions and the requirement for accurate fixtures.

Faster calibration

The unique ‘inferred calibration’ technique developed for PH20 determines the head orientation and probe position in a single operation, allowing subsequent measurement at any head angle. Further modules only require a few touches on the calibration sphere before use (enhanced metrology performance is available if needed by calibrating the probe tip at the feature orientation).

These dramatic time savings accumulate as the calibration process is repeated on a regular basis to comply with quality procedures or following a probe crash.

Integral industry standard TP20 probe

Users of the PH20 probe head will immediately have access to the range of proven TP20 probe modules, providing a wide selection of trigger forces, directional sensing options and extensions to meet application requirements. The detachable modules provide crash protection and can be automatically changed using the TCR20 change rack.
