1-18 NC2 general

Introduction

This section of the guide describes how to installand maintain the Renishaw NC2 non-contactbroken tool detection system.

The NC2 is a laser-based non-contact toolbreakage detection system specifically designedfor solid centred tools, for example drills and taps.

The tool is moved into the beam, the output isactivated by the latch input line, and the NC2“latches” the output if light is detected upon thereceiver.

Software routines

Examples of programs for high-speed broken tooldetection of solid tools are available for a widerange of machine controller types. Please refer tothe Renishaw website at www.renishaw.com andthen search for “NC2 software”.

Power supply

The NC2 can draw its power from the CNCmachine’s 12 V to 24 V nominal d.c. supply. Itsinput voltage range is 10 V d.c. to 30 V d.c.maximum and it presents a load of up to 35 mA.

Alternatively, the NC2 can be powered from aRenishaw PSU3 power supply.

Cleaning

Cleaning may be required if the air to the NC2becomes contaminated or if the system is leftwith the air off when coolant is present.

Excessive contamination will block the laserbeam and prevent the NC2 from functioning. Inthis condition broken tools will not be identifiedand the LED will be permanently lit red.

Achievable set-up tolerances

The tolerance to which a tool can be checked isdependent on the perpendicularity of the laserbeam to the machine spindle axis.

A typical perpendicularity value sufficient for mostapplications is as follows:

spindle axis ≤ 0.1 mm

This value can be refined to suit individualapplications.

Aligning the NC2

Aligning the NC2 involves making smalladjustments to the unit in the Z-axis until the laserbeam is perpendicular to the machine Z-axiswithin the set-up tolerance. This determines theminimum length of broken tool which can bedetected.

To check the perpendicularity of the beam,determine its position at two points – P1 and P2(see below).

NOTE: It is recommended that the distancebetween P1 and P2 is at least the size of themaximum tool diameter.

Use a piece of flat-bottom ground bar of knownlength and diameter held in the spindle. Manuallywind the calibration pin into the beam at P1 andP2 and monitor the status LED to determine thebeam position (green indicates that the beam isnot broken, red that the beam is broken).

NC2 alignment


1-21

Determining the checking position

The centre line of the beam has to be determinedfor use by the high-speed tool detection program.

1. At a point approximately midway between P1and P2, manually wind the calibration pin intothe laser beam from above.

2. Use the LED to determine the beam positionat this point. It should be possible to find theposition within 10 µm.

3. Repeat steps 1 and 2 to find the left and righthand sides of the laser beam. The midpointbetween these points is the beam centre line.

4. Input this checking position into the memorylocations accessed by the high-speed tooldetection program.

NC2 alignment

To adjust the beam, raise or lower the receiverend of the NC2 as follows:

1. Slacken the single securing screw at thereceiver end.

2. To raise the receiver end of the NC2, tightenthe adjusting screw.

To lower the receiver end of the NC2, loosenthe adjusting screw.

3. Gently tighten the single securing screw.

Now determine the position of the beam again atP1 and P2, repeating steps 1 to 3 as appropriateuntil the required perpendicular alignment isachieved.

After alignment has been achieved, tighten thesingle securing screw to 1.3 Nm (0.96 lbf.ft).

The SSR output is protected by a resettable fuse.To reset, remove the power and the cause of thefault.

NOTE: Connect the screen to the machinecontroller protective earth (also referred to as‘PE’, ‘starpoint’ or ‘Earth plate’).

High-speed tool breakage detectionon/off

An M-code is required to activate the toolbreakage function. The M-code must supply aconstant voltage of 10 V to 30 V to the grey wire.To deactivate the tool breakage function, the greywire is returned to 0 V.

Recommended feedrates

It is recommended that a feedrate of 2 µm-per-rev.is used for a minimum of three measuring moves.A span of 5 µm over three measurements isachievable.

Software routines

Software routines for tool setting using variousmachine controllers are available from Renishaw.They are described in data sheet H-2000-2289(see www.renishaw.com).

Introduction

This section of the guide describes how to installand maintain the Renishaw NC3 non-contact toolsetting system.

The NC3 is a laser-based non-contact tool settingsystem that provides high-speed/high-precisionmeasurement of cutting tools on a machiningcentre under normal operating conditions.

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.

Status LED

The LED on the NC3 indicates the status of thelaser beam:

Green = Laser beam is unobstructed

Red = Laser beam is obstructed.

Achievable set-up tolerances

Tool setting applications

The tolerances to which a tool can be set isdependent on the parallelism of the laser beam tothe machine axes. A value of 5 µm over a span of50 mm perpendicular to the Z-axis and 1 mm tothe X or Y-axis is easily achievable. This settingaccuracy is sufficient for the majority of toolsetting applications.

Tool breakage detection

A value of less than 0.1 mm (0.0039 in) maximumover a span of 50 mm perpendicular to the Z-axisand 1 mm with X or Y-axis is achievable. Thisshould be sufficient for the majority of toolbreakage applications.

NC3 alignment

Aligning the NC3

Aligning the NC3 involves making smalladjustments to the unit in the Z-axis until the laserbeam is parallel to the machine X or Y-axis withinthe set-up tolerances.

You will need to run the Renishaw NC softwarebeam alignment cycle before physically aligningthe NC3 (for details of this cycle, refer to theRenishaw non-contact tool setting systemprogramming guide).

After running this cycle, you will be able toascertain whether the laser beam is parallel to themachine X or Y axis or whether the receiver endof the NC3 needs to be raised or lowered withrespect to the transmitter end.

To raise or lower the receiver end ofthe NC3

1. Slacken the single securing screw at thereceiver end.

2. To raise the receiver end of the NC3, tightenthe adjusting screw.

To lower the receiver end of the NC3, loosenthe adjusting screw.

3. Gently tighten the single securing screw.

4. Run the beam alignment cycle again todetermine whether the beam is parallel to themachine X or Y-axis or whether furtheradjustments need to be made to the NC3.

Repeat steps 1 to 3 as appropriate.

5. After alignment has been achieved, tightenthe single securing screw to 1.3 Nm(0.96 lbf.ft).

Installation – NCi-4 interface

Introduction

The NCi-4 interface should be installed in theCNC control cabinet. Where possible, locate theunit away from potential sources of interferencesuch as transformers and motor controllers.

The interface processes signals from the NC3and 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 the NCi-4interface, ensure the machine is safe to

work on. Switch off machine power when workingin the control cabinet.

Install and configure the NCi-4 interface asdescribed in the publication “NCi-4 installationand user’s guide”, Renishaw part no.H-2000-5236.

What to do next

After you have finished installing the NCi-4interface, apply electrical power to the interface.

After the interface has been powered, switch onthe air supply and set the air pressure.

Installation – applying electrical power

Applying electrical power tothe interface

WARNING: Before switching onelectrical power, ensure the machine is

safe to work on.

1. Ensure that the NCi-4 interface and airsupplies have been connected correctly.

2. Switch on electrical power to the interface.

3. Check that the status LED on the NC3 unit islit.

Power loss and restoration

If electrical power to the NCi-4 interface is lostand then subsequently restored when the NC3system is in a normal operating mode, the NC3powers down and then powers up again withoutloss of the original gain settings.
