Hi i am new here so sory if i am not posting this in the right forum.
So i am working on Maho500w machine at work, we write our programs manualy.
So here is my question is there someone who can teach or explain to me how to use parameret programing, and how can i use the built in calculator in the machine, so my problem is this,
when i am milling bigger parts i use solid cam but i am not always using it cuz sometimes its faster to type in by hand,

so my program would look like for a 50x50 rectangle with the tool of the radius starting from r16 and going down to r10

1.G18 S1600 T93 M6 (R16)
2.G0 X-20 Y10 Z20 F600 M3
3.G1 Y0
4.G43 X0
5.G41
6.G1 Z-50
7.G1 X50
8.G1 Z0
9.G1 X-20
10.G40
11.G0 Z20
12.G1
13.T94 M67(R15)
14.G14 N1=4 N2=12
15.T95 M67 (R14)
16. G14 N1=14
17. T96 M67(R13)
18.G14 N1=14
19.G0 Y50
20.M30

So here is an example my target here is to decrease the tool radius by 1mm so i dont mill alot with the dept of the part but sometimes the part is 60x60 instead of 50x50 what it will be so thats alot of writing to decrease the R of the tool manualy, so i was hoping for someone to teach or explain to me how can i use these expresions on the machine : - + x cuz they are there but i dont know to incorporate them into my program,or to explain to me parameter programing i sort of used that but only what i was tryuing at work by myself, or if someone can help me to make a macro or teach me to make a macro for stuff like these i would rly appreciate it.

Hope someone can help me.

books to read are by shinha and peter smid
these will give you the basic format for parametric programming but they will be for fanuc control you will have to adapt if your control is not a fanuc

this looks like you are repeating the pattern taking a cut each time by changing the tool offset each time with out changing the tool side milling a single x axis profile

#1=93
1.G18 S1600 T#1 M6 (R16)
2.G0 X-20 Y10 Z20 F600 M3
3.G1 Y0
4.G43 X0
5.G41
6.G1 Z-50
7.G1 X50
8.G1 Z0
9.G1 X-20
10.G40
11.G0 Z20
12.G1



(#1 is a local variable in fanuc)
#1=#1+1(change tool # by +1 this is what i would write for fanuc)
13.T#1 M67(R15)(tool data activation with no tool change)
14.G14 N1=4 N2=12 J=6(repeat 6 times? 7 times total )



19.G0 Y50
20.M30

hope this helps
