Probe moves

Probe trigger

A.probe.trigger.signal.is.generated.when.the.probe’s.stylus.is.driven.against.a.surface..The.machine’s.control.records.the.contact.position.and.instructs.machine.motion.to.stop.

To.ensure.a.trigger.signal,.drive.the.probe.against.the.workpiece.to.a.target.beyond.the.expected.surface,.but.within.the.limits.of.stylus.overtravel..After.the.probe’s.stylus.touches.the.surface,.reverse.clear.of.the.surface.

single and double touch probing

If.the.probe.operating.sequence.is.based.on.a.single.touch,.then.the.probe.is.returned.to.its.start.point.following.a.measuring.move..

On.some.types.of.controller,.it.is.desirable.to.use.a.two.touch.method,.as.poor.accuracy.and.repeatability.can.result.at.higher.feed.rates.

With.a.double.touch.sequence,.the.first.move.finds.the.surface.quickly..The.probe.is.then.backed.off.to.a.position.clear.of.the.surface.before.making.the.second.touch.at.a.slower.feed.rate..This.records.the.surface.position.at.a.higher.resolution.

Probe measuring speed

The.probe.system’s.transmission.delay.time.is.small.and.constant…Normally,.it.does.not.limit.the.probing.speed.because.it.is.cancelled.out.during.calibration.of.the.probe.on.the.machine.tool.

High.probing.speeds.are.desirable..However,.if.used,.a.probing.velocity.must.be.chosen.which.allows.the.machine.to.stop.within.the.limits.of.stylus.overtravel.and.the.measuring.capabilities.of.the.machine.

calibrating a system

Calibration.should.be.done.in.the.following.circumstances:

•. Before.the.system.is.used.

•. When.a.new.stylus.is.used.

•. To.allow.for.machine.thermal.growth.

•. Poor.relocation.repeatability.of.the.probe.holder.

It.is.important.that.calibration.cycles.are.run.at.the.measuring.cycle.feedrate.to.cancel.out.system.errors.

Make.measurements.in.every.measuring.direction.to.provide.complete.calibration.data.for.the.measuring.cycles.

�. Probe signal delay

There.is.a.nominal.delay.of.240.µs.with.a.repeatability.of.3.µs.for.each.interface,.from.the.time.the.probe.actually.operates,.to.the.MI.12/OMI.interface.outputting.a.probe.change.of.state..

Replacing batteries

Clean.and.dry.the.probe.with.a.cloth.or.paper.towel.before.removing.the.battery.cassette..Where.the.probe.has.been.exposed.to.coolant,.it.is.recommended.that.the.area.around.the.battery.cassette.is.cleaned.using.an.airline..

Replacing batteries

To.access.the.probe‘s.batteries,.remove.the.battery.cassette.by.rotating.the.securing.screw.45°.anticlockwise.(see.page.8)..

Take.care.to.avoid.damaging.the.cover.gasket..

When.inserting.the.batteries,.ensure.they.are.loaded.as.shown.(see.page.8).

take care to read the battery label as polarities are not common across manufacturers.

The.probe.is.protected.against.incorrect.loading.which.would.result.in.reversed.polarity..If.one.or.more.batteries.are.incorrectly.loaded,.the.probe.will.not.respond.

Do.not.mix.new.and.used.batteries.as.this.will.result.in.reduced.life.and.damage.to.the.batteries.

cAutIoN:. Appropriate.precautions.must.. be.taken.when.using.airlines,.in.accordance.with.local.regulations..Always.wear.eye.protection..Never.direct.the.flow.at.yourself.or.others.

!

cAutIoN:. DO.NOT.leave.exhausted… batteries.in.probe..DO.NOT.allow.coolant.or.debris.to.enter.the.battery.compartment..DO.check.correct.battery.polarity.
