CNC Probe Calibration

This exercise is going to demonstrate the process for CNC calibrating a stylus.

Step 1) I like to start each exercise fresh so let’s start a new program. Select the icon

shown to start a New Inspection program.

Step 2) Click on the Probe Head icon in the top left corner of the screen. You can also

click in the green area.



Step 3) Click on the stylus position marked 1 as shown in the picture. This tells the CMM

software what direction the stylus is pointing.

Step 4) Once you click on the stylus position 1 the X,Y,Z and IJK boxes will be populated. Nowwe need to enter the length and diameter of our stylus.



Step 5) Take a measurement for the Length as shown and the diameter of the stylus you

are using.

Step 6) As you can see I entered the Length as 58mm and the diameter as 2mm. This is

because I have a Renishaw TP20 touch probe and I used a 2mmx20mm stylus. Make sureto check whether you are in MM or Inches.



Step 7) Now we need to select the angles we want to calibrate. Be sure to watch the video

on this as I go through and explain the different ways of doing this.

Step 8) Once you have chosen the angles you want to calibrate, click then Add button as

shown.



Step 9) You should see the definition show up in the Datum Position windows as shownhere.

Step 10) Once you see the definition you created you can repeat steps 7 and 8 to build as

many probe positions as you need. I will add 2 more.



Step 11) As you can see I chose to rotate the head to A=90 B=0. Please do this and click

then Add button as shown.

Step 12) As you can see I also chose to rotate the head to A=90 B=90. Please do this andclick then Add button as shown. You will see them build in the bottom window as you do

this.



Step 13) Now that you have entered all the stylus positions you want, click the Start

button as shown and the machine should begin to calibrate the tips.

Step 14) Once the machine has stopped running you should see all 3 stylus definitions in

the top window. The green one is the active probe tip.



Step 15) Now lets choose position A=0 and B=0. To do this use the mouse and left click

1 time on the red button next to it and it will turn green as seen here. Now select OK andin about 2 seconds the head will rotate down.

Step 16) Now we are going to save the Calibration data so we can recall it if we need too.Click the Save As button as shown below.



Step 17) Once this screen appears you need to choose a folder and give the file a name. I

chose to call it the length and diameter as a description. Once done select ok. Watch thevideo for demonstration on re-opening the file.

You are finished calibrating the stylus.
