Renishaw is increasing its focus on the Czech Republic, where it will be introducing a new range of products at this year's MSV exhibition, being held in Brno from 18th to 22nd September.

Part of the wider 'Brno Fair', MSV is the Czech market's most important show for metalworking and engineering technologies, and is located close to the local Renishaw company, which was established in 2002 to offer support and demonstration facilities for local customers.

Now in its 48th year, MSV has become a truly international exhibition, and in 2005 attracted 105,000 visitors from 58 different countries, with almost 2300 exhibiting companies from 32 nations occupying 69,000m2 of stand space.

This year it will run concurrently with the ITM, the 5th International Machine Tools Exhibition.

On show from Renishaw are products that will significantly reduce inspection times on both machine tools and co-ordinate measuring machines, and allow machines to run unmanned under full process control.

Other breakthrough products include a new angle encoder and high accuracy linear encoder for precision position feedback, and new software for motion system analysis.

At MSV, Renishaw is showing two new PC-based software products that offer significant time savings for users of machine tool probe systems.

Productivity+ Active Editor Pro is part of Renishaw's new generation of easy-to-use probing and process control software, which targets the entire spectrum of probe users.

The CAD front-end allows features to be identified with a single click, and the drag-and-drop interface uses the measured data to update machine parameters.

The result is a fully integrated metal cutting and probing program, which allows a machine tool to make intelligent decisions on the fly.

Renishaw OMV is a verification package that gives machine tool users powerful CMM-style 3D verification against a CAD model.

The software is targeted at manufacturers of complex and large parts, such as mould tools, and combines free-form and geometric features.

A straightforward point-and-click approach means that the user can see the inspection path as it is generated, and make changes if required.

In combination with Renishaw's nonlobing, high accuracy spindle touch probes, such as the MP700 and new OMP400 ultracompact touch probe, Renishaw OMV provides unrivalled accuracy of part verification on machine tools.

The most significant advance in co-ordinate measuring machine (CMM) technology for 20 years, Renscan5 is a new enabling technology that will allow highly accurate, ultra high speed five-axis scanning measurement on CMMs.

Receiving its Czech premiere at MSV, this new technology allows the development of a range of breakthrough five-axis scanning products that will measure at speeds of up to 500mm/s, and virtually eliminates the measurement errors normally associated with existing three-axis scanning systems.

The first product to take advantage of the new Renscan5 technology is Revo, a revolutionary measuring head and probe system that will maximise inspection throughput, while maintaining a high-level of system accuracy.

Revo uses synchronised motion when scanning to quickly follow changes in part geometry, without introducing its own dynamic errors.

This allows the CMM to move at a constant velocity along a constant vector while measurements are being taken, removing the inertial errors that result from acceleration of the machine during conventional three-axis scanning.

The new TRS1 tool breakage detection system allows manufacturers to run machine tools unmanned, with complete confidence that cutting tools damaged during a machining cycle will be quickly detected, eliminating the risk of scrapped parts.

This innovative new unit projects a beam of laser light at a tool and monitors the scattered light that is reflected, to determine if the tool has been broken.

It uses tool recognition technology that distinguishes between the tool and coolant or swarf/metal chips, and is also fast and reliable under real machining conditions.

More reliable than conventional noncontact systems, visitors to MSV will see that the TRS1 comprises a single unit containing the laser source and detection electronics, enabling it to be mounted outside of the working envelope, safe from collision and saving valuable space on the table.

For visitors to MSV interested in motion control, Renishaw's new Signum family of rotary and linear position feedback encoders offer ruggedness and precision to deliver levels of performance previously possible only from fine-pitch systems too delicate for many industrial roles.

All encoders feature comprehensive Signum software that enables optimum setup and real-time system diagnostics via a PC's USB port The Signum RESM angular encoder is a one-piece stainless steel ring with 20um scale marked directly on the periphery.

It features the In-Trac optical reference mark, which repeats, regardless of direction, at operational speeds of over 4500rev/min (52mm diameter) and up to 85C.

The Signum RELM high accuracy linear encoder comprises the SR readhead, Si interface and 20um RELM scale, which is offered in defined lengths.

Initially available in Invar, which provides a low thermal expansion of 1.4um/m/C, the RELM scale is offered with a choice of In-Trac reference mark positions and dual optical limits.

Together with the robust, yet highly precise 20um spars, this enables the RELM to offer accuracy to +/-1um and resolution to 20nm, satisfying the most demanding precision motion requirements.

MSV visitors interested in precision motion system analysis, will be able to see QuickView, a unique software package from Renishaw designed to make the ML10 laser an even more flexible and powerful analysis tool.

For years, electronic engineers have relied on oscilloscopes to study high-speed variations in voltage or current.

Now, QuickView software provides mechanical engineers with a similar capability, allowing them to study minute variations in linear or angular displacement, velocity or acceleration.

With a simple graphical interface QuickView allows very flexible operation, avoiding the need for predefined measurement targets and sequences - just point and measure, ideal for ad-hoc system investigations.
