can probe be used for reverse engineering

[1ctoolfool]

Can i make a Haas machine with a probing system "scan" a part surface?
I have done this with home made cnc but need to know if it can be done with like a VF1.

This would be a simple routine of collecting a series of points in a grid using the touch probe. The xyz data would be written out to a file.

The main issue is the correction of the offset actual surface point to the probe tip diameter. This is difficult to correct accurately and even cmm probing systems have these problems, but i can live with that if I can make a VF1 collect a set of points using the Rennishaw probe. If the probe tip accuracy became an issue I would like to use a laser rangefinder in place of the probe which supports RS232 coms.

The method I used previously was to write a simple macro that would scan a user defined grid at a user defined point density, then store the point cloud data as a text file.

Does anyone know of an application or have experience with this?
The questions I have are:
Can the Haas output each xyz "touch"
How fast can the probe respond. In other words what feedrate can the probe approach the work and still stop in time?
What is the G code for a probing command if any?

Thanks

I would second that post. I to would like to touch probe with a Haas. Curious as to what sofware you are using to collect the data and trace the points? I have not seen this on a Haas and it is very important for our needs.

Yes you can probe a part. Yes you can output X, Y, Z thru RS232.

Study the HAAS manual. If you do not have one, then go on-line and download a copy.

The on-line manual may include new functions that do not exist in older machines.

(edit) You can write your own code to do the probing. (end edit)

The answer is yes.
There is "Inspection Plus Software for Haas" manual by Renishaw,free from your Haas dealer.
I have .pdf copy of it. Let me know if you want it.
All macros are explained.And Haas has them all, much more then "Quick probe" from control.

please email me that manual you mentioned if it's not too much trouble.

If you could E mail it to me too that would be great :>)

Could you please send me a copy too. I am ready to buy a Haas mill, and am going to use the dightizing probe alot for my shop.

What you are trying to do is quite easy.
You can use the standard Renishaw Inspection Plus macros on the machine if you want - I also have the manual available.

We use an application called CNC Reporter to automatically gather data into an Excel Spreadsheet (so it is at least delimited etc.)

The key to improve accuracy is to calibrate the probe and to use as small a ball as possible.
A probe ball is calibrated in several vectors to compensate for not only physical size and physical run-out, but the speed of the skip signal also. What you end up with is a series of offsets - some for stylus position, some for radius of the ball. If you probe in a non calibrated vector - you cannot guarentee the accuracy of the output (unless you use a strain gauge probe - MP700). One way around this is to use a small ball, that way any inaccuracies are reduced.

Really you should probe any surface at the surface normal - for unknown part scanning this is not always possible.

We use Renishaw's prod+ software and there is the facility to probe either a radial or linear grid, and output all the points via a DPRNT. We then collect them via CNC Reporter into Excel in real-time and post process for a point cloud that is then taken into our CAM package.

Can someone send a copy of this manual to pbsxs AT yahoo.it?

Thanks in advance,

I'm not sure if you are asking to inspect a part for the purpose of reverse engineering or for in-process/final inspection. We use the HAAS probes extensively, and I'm not aware of the ability to inspect parts on unknown dimensions for the purpose of copying or reverse engineering parts. As for inspection to known dimensions, Renishaw Inspection Plus is what we use. As for data collection easyDNCXP is the software we use. All data is capture and transmitted vis RS232 to a PC using EasyDNCXP.

I use a laser scanner for reverse engineering, I need to use the probe for in process inspection and I was looking for the Renishaw Inspection Plus manual if you can.

Thanks,
Sandro

Here is the manual you requested. If you need help with developing code let me know.
