Manual Tool change Principals

[DaveCVI]

Hi,

Hi
Sorry for my late response, I am quite busy and first had to sort my cnc PC out as it seems to cause some of my problems.

On basic question I have - will you recommend me to use the gauge line to specify my TCP TP? Since my Spindle can touch my touch plate i see no reason why not - but first wanted to confirm this.

That is the easiest way to do it. Using the gauge line removes the need to accurately measure a tool as part of the boot strap process to set up the TCP TP.

The master tool must always be the same length/height. Bu I am using a collet. will it have an effect if I not always tighten the collet the same - as long as my bit is always the same length.

If you can't mount the master tool in a repeatable height holder, you can still make it all work.
In master tool mode, the non-master tool TLO values are relative to the Master length. Thus you do not want to change the length of the master (as it invalidates the TLOs for all other tools).
However, if you follow this rule:
**** always measure each and every tool every time it is mounted *****
you will be OK.
The master will get measured ever time it is mounted - that invalidates the other TLO values, but if the other tools ALSO get measured every time they are mounted, they will get new TLO values just before they get used (during the M6 steps).

Do NOT do this: put the master in a NRH holder (like a collet) and then attempt to use the "Skip RH tools" option on the tooling page.

hi,

Hi
I have installed the professional version and tried to setup my tpc tp.
I defined the tcp to be x:+7,9345, Y: +101.1963 and Z: -11.1988

X & Y can be where ever you want them to be for the TCP, so can Z. However, since most machines home to the top of Z travel. That usually puts Z0 (in machine coordinates) at the top of travel.
So I usually see the TCP in MCoords as being Z0... not Z=-11.1988 - but if you want the TCP to be below the top of Z travel, that will work too. I'm just noticing it as it's more common for TCP to be at Z0 (in machine coords).

The touchplate is close to z - 167.8763
I want to use the gauge line to define the location of the touch plate.

OK, to set up the TCP TP, you use the "Set TCP TP MCz" button on the settings page. See the manual for that button - the process will locate the TCP TP along MCz and store the location of the plate.

I then click on go to TCP
then I want to click Set TCP TP MCz. but am getting an error MaxZDist <= MinProbeDistance, Op Cancelled

The TCP TP is found by doing a probe operation to lower the spindle to the plate. Since this is a probe operations (even though it is using the plate instead of aprobe tool), the operation is subject to the pro0bing parameters on the WC offset, probing page.

Check these settings:
Probing page: "Max Z Distance" is this value large enough to cover the distance between the spindle when at the TCP and the top of the TCP TP? If not make the value larger. I'm guessing it may be set to 0 (a rather small max probe distance).

Setting page: Under the "TCP TP installed" button are two DROs. On is labeled "Max Dist" - this is the max distance the spindle will probe when trying to use the TCP TP. What is this value? Is it zero?

Hi
I want to ask some more questions:
a) I have attached screen dumps of all my pages as well as my msm xml file. Will it be possible for you just to look at it and give advise on my settings. I have set tool 200 to be my master tool and also defined my TCP TP on my gauge line.
b) When I jog to stock. Then when I go to tooling and click on Set Z Zero, but nothing happens.
c) can you help me to double check all my machine stettings on MSM to make sure all my settings ae 100%I am refering from ensuring my calibartions to my other settings are correct. Or will it alwyas means that if the settings are correct in Mah3, it should also be correct in MSM?

Regards

I also have another question.
I have a movable touch plate being 2mm thick. I use this plate in my set z zero on my wood stock. Where do I define this?

Thanks

Hi,

Hi
I want to ask some more questions:
a) I have attached screen dumps of all my pages as well as my msm xml file. Will it be possible for you just to look at it and give advise on my settings.

I took a quick glance, but I really don't have the time to look at every setting and think about how it relates to all the other setings and how that in turn relates to whatever you may be trying to do when the screen shots were taken, Sorry, but the combinatorics for that are large.

I'm also going to decline looking thru the mach XML file.
MSM does not store any MSM settings in the mach XML. Therefore there is nothing in there that MSM needs to operate. i purposely designed MSM to be as independent of mach XML settings as possible - that way crud people put in the mach XML do not impact MSM and vise versa.

here are some misc things I did notice:
a) machine is set up in metric units I assume
b) you have tool 200 mounted - that's both the probe and the master tool.
I find it a bit odd that you do not have TLO on for the tool. It seems a bit unusual to mount a probe tool, but nto have the machine using the TLO value for the tool. Normally the tool change sequence is:
T# M6
G43 H#
You appear not to have done the G43 part of the sequence.
This could be intention on your part - I can;t tell what you were doing when the screen shots were taken etc.

c) Probe feed rates are slow. I see (hard to read in the screen shots) 150 fast and 50 slow.
In imperial I usually probe at 40 inches per minute (1000mm) and 15 IPM slow (381mm).
I never go below 10 for the slow rate as this causes bounce on the probe - see the manual sections about settign up probe parameters.

d) probing X,Y, Z clearance froma probe is set = 0.
Make that a non-zero number. A 0 Z clearance is asking for trouble as thi s leaves the probe exactly at the trigger point where is will be going on and off with the least vibration.... give it some clearance after the probe movement. Typical mount is imperial 0.1" or 2.5mm

I have set tool 200 to be my master tool and also defined my TCP TP on my gauge line.

OK

b) When I jog to stock. Then when I go to tooling and click on Set Z Zero, but nothing happens.

Watch the Z row of the upper panel carefully. move the spindle up and down in Z, click the "Set Zero" button and you will see the WC offset value in the Z row change.

c) can you help me to double check all my machine stettings on MSM to make sure all my settings ae 100%I am refering from ensuring my calibartions to my other settings are correct. Or will it alwyas means that if the settings are correct in Mah3, it should also be correct in MSM?

See above - MSM and Mach Setting are independent.
