Introduction

This guide describes how to install, configure,maintain and service the Renishaw NC4 non-contact tool setting system.

The NC4 is a laser-based non-contact toolsetting system that provides high-speed/high-precision measurement of cutting tools on amachining centre under normal operatingconditions.

As a tool moves through the laser beam, thesystem detects when the beam is broken. Outputsignals sent to the controller allow the presenceof a tool and the position of the tip (broken tooldetection) to be established.

Guidelines for good practice

● The NC4 is a precision device and must behandled with care.

● Ensure that all mountings are secure.

General

● Cables, piping, conduit, etc. should besuitably secured to avoid damage and loadsbeing transferred to the NC4.

● Mount the system in a position that limitsthe risk of it being subjected to impact whenoperating the machine.

● Mount the system in a position where it willnot be affected by a build-up of swarf. Donot allow excessive waste material to buildup around the NC4.

● Keep electrical contacts clean.

● Optimum performance is achieved bycontinuously supplying air and power to theNC4.

● The NC4 is protected by a continuousstream of clean air. Approximately once amonth, inspect the optics for contamination.The service interval may be extended orreduced dependent upon experience.


11General

● The vent at the bottom of the NC4 must beleft uncovered to allow reliable operation ofthe PassiveSeal.

How to install and configurethe NC4 system

Install and configure the NC4 system in thesequence described below:

1. Install the air assembly kit (see “Installingthe air assembly kit” on page 31). Do notswitch on the air supply or set the airpressure at this stage.

2. Install the NC4 system (see “Installation –fixed systems” on page 32 or “Installation –separate system” on page 37.

3. Install the interface unit (see “Installation –interface unit” on page 45).

4. Switch on electrical power to the interfaceunit (see “Applying electrical power to theinterface unit” on page 47).

5. Switch on the air supply to the NC4 systemand set the air pressure (see “Setting the airpressure” on page 48).

6. Align and set up the NC4 system (see “Set-up and alignment – separate system” onpage 54 or “Alignment and set-up – fixedsystems” on page 59.

28 NC4 set-up tool

Introduction

The NC4 set-up tool is a battery-operated devicethat is used to provide a visual indication of thesignal strength at the NC4 receiver unit. Thesignal strength is shown on a numerical display.The higher the number, the greater is the signalreceived at the receiver unit.

The set-up tool is placed over either thetransmitter or receiver unit and is rotated so thatthe display can be easily viewed. Placing the toolover an NC4 unit activates the numerical display.Removing the tool causes the display to power-off.

NOTE: The numerical display provides only anindication of the signal strength. If a true readingof signal strength is required, a voltmeter mustbe connected to the appropriate connector pinson the interface unit.

The set-up tool can be used on fixed andseparate NC4 systems.

Battery specification

The set-up tool requires one ½ AA size battery,rated at between 3.3 V and 3.6 V. It is importantto ensure that the battery is supplied in standard(button) form. Batteries that are described astagged have additional connection tag featuresfitted to the terminal and are not suitable.

30 Installation

Introduction

The air supply to the NC4 must conform to ISO8573-1 air quality of class 1.7.2 and be moisture-free. If the air quality cannot be guaranteed, anoptional de luxe air filter unit is available fromRenishaw (see “Parts list – air supplyaccessories” on page 98).

The NC4 requires a continuous regulated airsupply of between 3 bar (43.5 psi) minimum and6 bar (87 psi) maximum.

Failure of the air supply allows a PassiveSealinside each NC4 unit to protect the unit from theingress of contaminants. This causes the unit toenter a trigger state. The laser beam will not beseen exiting the transmitter unit, and the statusLEDs on the transmitter and receiver units willdisplay red (when the tool setting mode isselected).

The cause of the air failure should be determinedand rectified.

Best practices

● Where possible, tap into the air supply thatexits the machine air supply filter / regulatorunit. Do not connect the NC4 to an oiled airsupply.

● Use blanking plugs, supplied with the airassembly kit, when feeding air pipe throughthe conduit / machine.

● Before connecting the air pipe to the inlet ofthe NC4 unit, briefly switch on the air supplyto clear out any debris from the pipe. Whenno more debris is emitted, switch off the airsupply and connect to the NC4.

● When installing the air pipe supply to theNC4, keep runs as short as possible tominimise pressure drop.

● If the temperature of the air supply isgreater than 5 °C above ambient and ishumid, an air drier will be required.

Installing the air assembly kit

WARNING: Before starting to install thekit, ensure the machine is safe to

work on.

1. Secure the air regulator, vertically upright, toa suitable surface using the mountingbracket. This must be within 25 m of theNC4.

2. Locate a source of clean air toISO 8573-1:Air quality class 5.7.–, andconnect it to the regulator inlet. Wherepossible, use air that exits directly from themachine tool air filter unit.

If the compressed air source is suspected ofbeing contaminated (e.g. if it is direct from themachine shop supply, if the machine tool filter isdirty, or if it is downstream of an oil mistlubricator) then a second air filter may berequired. A suitable filter unit is available fromRenishaw (see “Parts list – air supplyaccessories” on page 98).

What to do next

After you have finished installing the NC4separate system, install the interface unit.


45Installation – interface unit

Introduction

The interface unit should be installed in the CNCcontrol cabinet. Where possible, locate the unitaway from potential sources of interference suchas transformers and motor controllers.

The interface processes signals from the NC4and converts them into a voltage-free solid staterelay (SSR) output. This is transmitted to theCNC machine control, which responds to theprobe inputs.

!

Installing the interface

WARNING: Before installing theinterface unit, ensure the machine is safe


Install and configure the interface as described inthe publication “NCi-4 non-contact tool settingsystem interface installation and user’s guide”,Renishaw part no. H-2000-5236.

49Software – installation and routines

Introduction

Before installing the NC software, read theguidelines contained in the Readme file on thesoftware floppy disk or CD.

Software routines

Software routines for tool setting using variousmachine controllers are available fromRenishaw plc.

They are described in the data sheet “Probesoftware for machine tools”, Renishaw partnumber H-2000-2289 (see www.renishaw.com).

Example programs for high-speed broken tooldetection of solid tools are available for a widerange of machine controller types. Please refer tothe Renishaw web site at www.renishaw.com andthen search for “Non-contact tool settingsoftware”.

Recommended feedrates

It is recommended that a feedrate of 2 µm-per-rev. is used for a minimum of three measuringmoves.

A span of 5 µm (0.197 µin) over threemeasurements is achievable.


50 System alignment and set-up – general

Aligning the NC4

Aligning the NC4 system involves moving thetransmitter and receiver units so that the laserbeam is parallel / perpendicular to the machine’saxes. The alignment should be adjusted so that itis within the recommended tolerances detailed in“Alignment tolerances” on page 53.

The beam alignment macro described in thepublication “Non-contact tool setting systemprogramming guide” is used for this process. Themacro indicates how well the system is aligned.You can then use this information to makeadjustments to the NC4.

Setting up the NC4

Setting up the NC4 system involves adjusting therelative positions of the transmitter and receiverunits to maximise a test signal obtained at thereceiver unit. Do this with the interface unit inSet-up mode.

Either a voltmeter or an NC4 set-up tool are usedto provide an indication of the signal strengthreceived at the receiver unit.


51

Using a voltmeter

A standard voltmeter, that is within calibration,may be used for setting up and aligning the NC4system.

1. Position the voltmeter next to the receiverunit. Connect a wire between terminalCN2-1 on the interface unit and one of thevoltmeter probes. Connect a second wirebetween terminal CN2-2 and the othervoltmeter probe.

2. On the interface unit, set switch SW1-2 (NCset-up) to ‘On’.

NOTE: If a negative reading is obtained whenyou use the voltmeter, swap over the voltmeterprobe connections.

Using the set-up tool

The set-up tool numerical display provides acorrect reading only when the interface unit is inthe Set-up mode – that is, when the NC set-upswitch (SW1-2) is set to ‘On’.

1. Check that the NC4 receiver unit is cleanand free of swarf. Push the set-up tool ontothe top of the receiver unit and rotate it sothat the display is facing you.

53

Alignment tolerances

The tolerances to which a tool can be set aredependent on the parallelism of the laser beamto the machine axes.

Tool setting applications

Over a span of 100 mm (3.94 in), the followingalignment accuracies are easily achievable:

Spindle axis (P2 – P1) = ≤10 µm (0.39 µin)

Radial axis (P2 – P1) = ≤1 mm (0.39 in).

These values are sufficient for the majority oftool setting applications.

Tool breakage detection applications

Over a span of 100 mm (3.94 in), the followingalignment accuracies are easily achievable:

Spindle axis (P2 – P1) = ≤0.2 mm (0.0079 in)

Radial axis (P2 – P1) = ≤1 mm (0.39 in).

These values are sufficient for the majority oftool breakage applications.

Setting up and aligning aseparate system

WARNING: Before setting up andaligning a separate system, ensure the

machine is safe to work on.

To set up the system

1. Either connect the digital voltmeter asdescribed in “Using a voltmeter” on page 51or fit the NC4 set-up tool as described in“Using the set-up tool” on page 52.

2. Switch on electrical power to the interfaceunit.

3. Ensure that air is supplied to the NC4 and isat the correct pressure.

4. Slacken all conduit clamping screws so theNC4 units can move freely.

5. On the mounting plate of the transmitterunit, use a 3 mm hexagonal key to slacken

the two translation holding screws and tworotation holding screws to allow the plates tobe adjusted (see the figure on page 55).

6. Adjust the rotation and pitch of thetransmitter until the laser beam shines onthe centre of the receiver MicroHole.

7. Load a tool into the spindle of the machine.A solid, flat bottomed tool is preferred.

8. Remove the target from the back of thisguide. Using either Blu-tack or adhesivetape, attach it to the tool as shown in thefigure on page 56.

9. Starting close to the transmitter (targetposition 1) (see the figure on page 56),manually traverse the spindle / machinetable so that the laser beam is centred withthe target cross hairs.

10. Manually traverse the target / transmitter sothat the target moves away from thetransmitter and towards the receiver (targetposition 2).

11. Adjust the rotation and pitch of thetransmitter unit so that the laser beam isrepositioned on the cross hairs.

12. Go back to target position 1 and manuallytraverse the target / machine table to re-centre the target with the laser beam.

13. Repeat steps 10–12 until the laser spotremains on the centre of the cross hairs asit traverses along the measuring gapbetween the transmitter and receiver.

14. Finally, tighten the translation and rotationholding screws to 3.0 Nm (2.2 lbf.ft), using a3 mm hexagonal key, to lock the pack inposition.

15. On the receiver adjuster pack, slacken thetwo translation holding screws and tworotation holding screws to allow the plates tobe adjusted.

16. If it is possible to reach the receiver adjusterpack with the machine spindle, clock the topand side of the receiver adjuster top plate.

This ensures that the receiver unit isparallel / perpendicular to the machine axis.

17. Translate and rotate the receiver until themaximum signal is obtained on thevoltmeter or set-up tool.

Check that either:

● the voltmeter reading is between 1.0 Vand 7.0 V, or

● the set-up tool reading is between 1.0and 7.0.

18. Tighten the translation and rotation holdingscrews to 3.0 Nm (2.2 lbf.ft) to lock the unitin position.

19. Check that the laser beam is not obstructed.

On the interface unit, set switch SW1-2 (NCset-up) to ‘Off’.

Check that:

● the probe status LED is green, and

● the voltmeter reading is between 4.7 Vand 5.3 V.



NOTE: If the set-up tool is used, ignore thereading on the display. A false reading isshown when the NC set-up mode isswitched off.

If the beam is blocked when the switch isset to ‘Off’, the system will be unable to setitself correctly. If this occurs, remove theobstruction then set switch SW1-2 (NC set-up) to ‘On’ then back to ‘Off’.

20. Next, align the system.

To align the system

1. Run the beam alignment macro (see thepublication “Non-contact tool setting systemprogramming guide”).

2. If the alignment is outside the valuesdescribed in “Alignment tolerances” onpage 53, the system requires aligning.

Calculate the required correction movebased on the output of the alignment cycleand the system separation.

Start by moving the receiver unit, as thisdefines the effective beam path. If possible,use a dial test indicator on the receiverhousing to control the correction.

3. On the interface unit, set switch SW1-2 (NCset-up) set to ‘On’.

4. Re-adjust the transmitter until the maximumsignal is obtained on the voltmeter or set-uptool.

Check that either:



5. On the interface unit, set switch SW1-2 (NCset-up) to ‘Off’.

6. Run the beam alignment macro again.

7. When the system is aligned correctly,tighten the conduit clamping screws.

Cleaning the optics and servicing thePassiveSeal should only be carried out bypersonnel who have received training in the useand operation of laser products. Special tools,such as the cleaning tool and pin spanner,should only be used by service personnel.

Cleaning the NC4

If the air to the NC4 becomes contaminated, thetransmitter and receiver units may requirecleaning.

Contamination will cause the system to stay in atriggered state. If contamination is suspected,identify the cause and rectify the problem beforecleaning the NC4 system. If necessary, changethe air pipe.

Clean the units one at a time to reduce the riskof mixing up the access panels.

Equipment required

● Pin spanner.

● Cleaning tool.

● Solvent Cleaner Plus (RS No. 266-0856) orsimilar.

● Dust Remover clean air spray (RS No.846-698).

● Polyester cleaning swabs (2-off).
