Explained in three points:
1. Program the exploration points************
2. Edit the processing program *********
Third, add macro variables********** in EXCEL
The first section compiles the exploration program
1. Set the origin and find the coordinate values of each probe point.
First set the origin of the workpiece coordinate system in the UG software, and then use the UG software to find the points (X Y Z) where the probe points are needed and record them for programming the probe points.
2. Program the exploration points
(The name of the exploration program is determined by yourself: O6666)
To control the movement of the probe in the probe point program, two important probe calculation programs O9810 need to be called.
and O9811. Exploration point program format example: (The following is an example of compiling Exploration Z point)

If it is to probe the side, S is required, that is, the angle of rotation, so that the probe can detect each side. They are all measured using one surface of the ruby ball probe to reduce errors.

Section 2 Editing Processing Program
Add the compensation value variable (#601#602 #603...) corresponding to each probe point to the coordinates of the corresponding point in the processing program. (Here we use the Z value to explain. The principle of compensating the X and Y directions is the same as compensating the Z direction.): (That is, two points are directly connected, each with a Z value)
From point A to point B, the compensation differences of probe points A and B are #601 and #602 respectively. If you want the tool to make a general transition from A to B, you only need to add the Z compensation value variables of points A and B to the corresponding machining program.
The following is the processing procedure: (taking the compensation Z value as an example)

Section 3: Quickly edit processing programs in EXCEL
Sometimes it is necessary to add variables to N multi-line programs. If you add them one by one manually, it will be very difficult.
Troublesome, heavy workload, and error-prone. Here is a way to use EXCEL to quickly edit programs.
picture
How to change:
1. First copy the program to which variables are to be added into Notepad, as shown below:
picture
2. Replace X with "/X/", replace Y with "/Y/", and replace Z with "/Z/", as shown in the figure:
picture
3. Open EXCEL and open the file in step 2. Note that in the open dialog box, select the file type as
"All files", then open the file in the previous step, and a dialog box will appear as shown below:
picture
4. Click Next and the next dialog box will appear, as shown below:
picture
5. Check "Other (0)" and enter a slash "/", as shown in the figure:
picture
6. Then, select "Next" and "Finish" to open the file. You can see that each part is separated.
What you want is this effect, as shown in the picture:
picture
7. Add Z and the number 16.31 to each line of the program, as shown in the figure
picture
8. Manually add variables to the starting point and end point. Since the point in the first line is the starting point, the variables should be detected accordingly.
Compensation value #601, the 14th line in the above picture is the end point, the variable should be the corresponding detected compensation value #602
The variables in the above two points can be added manually, as shown in the figure:
picture
9. To add variables at the middle point, you need to add the variables shown in Figure A above. The method is to first move the square brackets and plus signs to each line in the middle, and then enter the variables to be added at the middle point as shown in the third line of the picture above. Variables such as #690*1
(Here, the difference between the compensation values of the end point and the starting point is evenly distributed to N intermediate points. This is divided into 12 segments. The relationship is #690=[#602-#601] / 12. This relationship requires add it to the program)
Then first hit "#690*1" and pull it down to achieve it, as shown below:
picture
Then save EXCEL as a text txt file, and then open it with Notepad, as shown below:
picture
Delete the empty distance in the middle and add its corresponding macro variable relationship #690=[#602-3602]/12 in front of the starting point as shown below:
