Accuracy and repeatability is the lifeblood of all CMMs. If they aren’t accurate, there’s no point in having them. However, the degree of accuracy required is dependent on the particular application. For manufacturing gas turbines and aircraft engines, a very high degree of accuracy is often required.
Well, that level of accuracy can be achieved with high precision rotary tables. These can deliver precision geometry with axial performance well below 0.0005mm and positional accuracies to ±0.5 arc-seconds (±0.00014°).
Using a rotary table on a CMM will improve process efficiency and productivity by reducing setup and process times. A rotary table will also greatly increase a CMM’s available measuring volume thereby providing greater flexibility in what can be measured. And last but by no means least, a rotary table will also significantly improve overall measurement accuracy of a CMM, thereby reducing uncertainty.
Rotary tables enable very precise measurement of many geometrical characteristics, including angle, roundness, concentricity, parallelism, flatness and runout. They are used with: probes such as plunger, transducer and capacitance; optical such as autocollimator and laser interferometer; and electrical: oscilloscope and voltmeter.
Rotary tables enable accurate measurement of symmetrical/prismatic components such as rotor discs. In the measurement of a rotor disc, a CMM without a rotary table would require a machine with a large measuring volume. However, deploying a rotary table will reduce this volume significantly. This is because the volume of the CMM is directly related to the diameter of the disc as voluminous styli systems are usually required to measure a workpiece from all sides. This means a large proportion of its measuring range is required just to ensure collision free movement of the stylus around the part.
However, the introduction of the rotary table removes this requirement as the rotor can be presented directly to the stylus removing the requirement to access all sides. This in turn simplifies the stylus system allowing the measurement of larger workpieces in relation to the available measuring range, saving aerospace manufacturers both time and money.
As well as significantly improving overall measurement accuracy and reducing uncertainty in CMMs, rotary tables also greatly increase a CMM’s available measuring volume thereby providing greater flexibility in what can be measured.
Some tables have been specifically designed as a fourth axis for any high precision CMM to simplify measurement procedures, increase application range and measuring volume of symmetrical or prismatic components, including scanning applications. This is particularly important for large turbine disks for gas turbines or for airplanes. However, they are also starting to gain traction for smaller, lower measurement volume applications typical in the automotive industry.
Air bearing spin tables are becoming more popular and rely on air lubricated hydrostatic bearings which provide very high radial and axial stiffness. This type of bearing offers significant advantages over conventional rolling element bearings permitting operation with minimal drag, vibration and mechanical noise.
These tables can be combined with direct drive motors and high accuracy angular encoders. The encoder couples directly to the motor control system, which has its own high-resolution interpolator ensuring precise positioning and repeatability.
It is possible to fit a table with a high accuracy Hirth Coupling, which provides location and angular positioning of the tabletop. This delivers fast, accurate indexing between pre-set positions.
Rotary tables are so accurate that they can be forgotten, when using a CMM. And that’s no bad thing for manufacturers who need precision time and time again.
CNC rotary tables play a vital role in the performance of multi-axis machining centres. As table accuracy and reliability are of paramount concern throughout the product"s lifetime, Matsumoto Machine Corporation (MMK) has taken a pragmatic two-pronged approach to reducing indexing errors and improving performance. By enhancing both product calibration and encoder technologies the company has set new standards for rotary table accuracy.
Founded in Japan in 1948, Matsumoto Machine Corporation is a technology-leading provider of innovative, high quality jaw chucks and numerically controlled rotary tables used by industrial machine tool makers throughout the world. A key feature of MMK"s CNC rotary tables is a patented worm and wheel gear assembly developed by OTT GmbH, Germany. Unlike double lead worm gears, the OTT worm and wheel gear is able to minimise backlash, ensuring outstanding accuracy and long life, efficiency and durability.
A further advantageous characteristic of the MMK CNC rotary table is a large diameter through-hole in the table spindle. This greatly increases machine versatility and rigidity, supporting a wider variety of chucks and jigs and the machining of longer workpieces.
By enabling most metal-machining operations to be undertaken on a single machine, the benefits of MMK CNC rotary table are far-reaching. These include the time and cost saving of single machine set-up and single fixturing setup, reduced parts handling and the elimination of tolerance errors as workpieces pass from machine to machine.
Of critical importance in this one-hit machining centre scenario is ensuring the high accuracy of CNC rotary table indexing and control throughout its working lifetime.
As with a machine tool"s linear XYZ axes, the rotary axis is just as susceptible to uncontrollable events that may introduce angular positioning or axis alignment errors. Risking the production of defects in finished parts, these errors can be due to a number of reasons including, mistakes made in the initial machine installation, impact damage caused by collision or general wear-and-tear in use.
With its global reputation for product quality and design innovation, MMK therefore sought to equip its CNC rotary tables with a highly accurate and reliable means of tracking and controlling the indexing of its product throughout its lifetime, irrespective of the type of machine tool, workpiece complexity and duty cycle.
At the same time, in an increasingly competitive global market for CNC rotary tables, MMK also wanted to further enhance its product quality inspection processes. Specifically, the company set itself the task of augmenting index angle measurement as a key component of pre-shipment quality assurance procedures.
To provide machine tool makers and users with the ability to accurately track and control CNC rotary table indexing, MMK elected to integrate Renishaw"s super-compact TONiC™ non-contact optical incremental encoder system. Simple to install and with a compact readhead measuring just 35 mm x 13.5 mm x 10 mm, the TONiC encoder presented MMK with a minimal footprint solution capable of supporting machine speeds up to 10 m/s and resolutions down to 1 nm.
The rotary table readhead was designed to be used in conjunction with Renishaw"s RESM, a one-piece stainless steel ring marked on its periphery with 20 µm pitch graduations and featuring the IN-TRAC™ optical reference mark. With its low profile, large internal diameter and wide choice of diameters from 52 mm to 550 mm, the high stability RESM ring provided MMK with a versatile and easy to integrate scale that is well-suited to the company"s wide range of CNC rotary tables.
MMK selected Renishaw"s compact and lightweight XR20-W rotary axis calibrator to verify the accuracy of its rotary tables during manufacturing and immediately prior to shipment. The XR20-W was used in conjunction with Renishaw"s XL-80 laser interferometer to provide a non-contact reference measurement, independent of the axis under test, with an accuracy of ±1 arc second.
Motorised by a servo-controlled drive and with data capture synchronised to axis movement, the XR20-W requires no operator intervention during measurement. Being lithium battery powered and Bluetooth enabled, it ensures quick and easy setup, and the avoidance of trailing cable hazards. The calibrator"s modular design and flexible mounting systems allow far easier setup than alternative solutions and can be readily configured for a wide variety of rotary tables, chucks and spindles.
By integrating Renishaw"s TONiC non-contact optical encoder system into its CNC rotary tables, MMK has further assured the accuracy and reliability of its products in the field, along with an overall superior motion control performance. For a wide range of different machine tools and end uses, the rotary tables" combination of compact readhead and one-piece stainless steel ring scale has delivered a higher level of tolerance to dust, scratches, grease and oil, and a reduction in indexing errors. The encoder system"s ability to output highly stable position signals of unrivalled purity and ultra-low sub-divisional error have provided smoother velocity control, improved scanning performance and increased positional stability.
MMK"s introduction of Renishaw"s XR20-W rotary axis calibrator and XL-80 laser interferometer has reduced product measurement times by a half compared to conventional autocollimator techniques. Measurement procedures have been simplified and automated. Capable of taking accurate measurements at any indexing angle pitch, the calibrator enables evaluation of the accuracy of the worm and wheel gear-driven table for ultra-fine pitch measurement movements as small as 0.001°. This has allowed any loss of motion control or worm and wheel gear efficiency to be evaluated in detail and addressed. Product performance is now backed by a thorough analysis meeting ISO quality standards.
