why doesn't go to correct diameter

[andrejculk]

I have a program:

T16 M6
S7000 M3
G0 G90 G17 X-61.5 Y0 E2
Z5 H16 M8
G1 Z-15 F1000
Z-16.2 F200
G1 G41 Y1 D16 F800
G91 G3 J-1 Z-1 L5
J-1 Y1
G90 G40 Y0
G0 Z5 …

Why I can't correct tool on width? Hole diameter must be 10 mm, but is 9.7 mm. Under correction of tool 15 (D15) I type -0.3, but Hole is still the same 9.7 mm. Is impossible to correct. Why?

putting that aside, I never use a minus ( neg. value ) in the "D". The only time I have seen it used is if you are programming using the center of the tool already incorporated into the tool path. In this case, on a climb cut, the minus (-) sign can be used to adjust the cutter to the left away from the cutting side, and the plus (+) sign toward the cut side. Its reverse on the conventional cut.
Most people program to the print drawing edge without adding in the tool path radius and define the tool as the diameter or radius depending on how the offset parameter is set for that machine.

The D value is D16.

I mean D16.

Reading the program sample you posted you state you are adjusting D15 but the program calls for D16.

Yes I was mistaken.

Me interest above all, or that it possible.

Because you don't have a lead in or lead out.

MM get me all screwed up but it doesn't look like you have a lead in on your g41 line in x , you also should have a lead out on your g40.
it looks like your circle starts at X61.5, you also have your g41 starting at X61.5
plus your ending Y is the same as your lead in Y.


It should read something like this

T16 M6
S7000 M3
G0 G90 G17 X-63.0 Y0 E2
Z5 H16 M8
G1 G41 X-61.5 Y1 D16 F600
G1 Z-15 F1000
Z-16.2 F200
G91 G3 J-1 Z-1 L5
J-1 Y1
G1 Z5
G40 D0 X-63 Y0
G90 G40 Y0
G0 Z5 …

you got it. you must have a linear move to start dia. comp--

[Dyad1]

Hi guys
What about considering the y and j numbers?
Where is the decimal point? Those numbers are showing .oo1mm
not 1mm. Remember the format for metrics is xxx.xxx for x,y,z,i and j.
His compensation is fine if those were correct.

[Delw]

I have no clue about metric, those numbers are alien to me LOL


I have found that you always had to have a x and y move for tool comp. and the amount of the move needs to be slightly more than the tool dia.

but then Again I could be doing something not needed for the fadal and had to have it on another control I used over the years,

the only other thing I was thinking is that the L5 was messing everything up. if I want it to go around teh part 5 times I just right the code I never use the L number. I dont think that is even the correct format for the L number is it?
as far as line numbers I assume they are in the code he just didnt post them.

I think the problem is, because the d16 code is after g41 code. It shud be before that g41 code line..?
