Sorry for off topic.
Hi wanting to contact Jerry (JWK42)
Jerry, please sent PM if you are still on CNCzone
Cheers. Kiwi
Yes That's correct
That line moves the cutter to start point
I'm not sure if the arc is G02 or G03
Suggest you try doing the arc in two moves. (see below)
G01 X-0.0469 Z0.0469
What about this?
Touch tool on top of plate and set as Z0.0469
G01 X-0.0469 Z0.0469
G01 Z0
G18 G02 X0.0469 R0.0469
G01 Z0.0469
G00 Z1
Please post some specs of the screw, length, pitch, dia of screw, dia of cutout, etc.

Use look a head G51 at the beginning of your code.
G51 E0.001
This code will machine an arc on XZ Plane rotated 45 deg and tilted 10 deg. Similar to pic on Post #5,.
Using Fagor Control. (The same should be doable with Fanuc using G68)
G18
G49 A7.1071...
Write you code for one plane eg G17 and Rotate using G68 (Fanuc)
The hardest part is determining the second plane angle when setting the controller, if your arc's plane is rotated on two planes.
Unable to see how the 7.7 is the centre of the bar. The 7.7 is the balance of 12.7 (radius of the offset turned diameter) less the 5 offset.
I also can not see how 33.58 is large enough as the...
Unable to download your attachment.
Please post picture of your drawing.
Hi, unable to confirm your macro, but if I have the dimensions correct, I think??? the G03 X-#102 value should be -15.4 and the G03 X#104 should be 35.4
Attached drawing as my understanding.
Could you please post the 5 axis code with the cutter at 90 deg for one pass along the ridge of the attached model. Wanting to establish the different XYZ points when the angles change. Thanks.
Another way to do with constant tool angle to part.
Generate path as 3D 3 axis as normal.
When machining, rotate part required tool angle and set controller to machine on this angle (Fanuc G68) but...
Can you touch off cutter at different angles and note XYZ as per drawing.
The number of lines of code is not the problem. Just sorting out the conversion.
Can you post one line of code with the tool perpendicular and also the code for the tool set at an angle for the same point of contact on the part?
Also about 10 lines of code.
I have never used simultaneous 5 axis and don't know MadCam capabilities.
It MAY be possible to modify the perpendicular code using a VB macro.
This would need investigating if unable to get MadCam...
I've never used G59 but would have thought this function worked the same as on a Fanuc controller.
I count about 30 threads for Fagor and about 660 for Fanuc control during 2015.
I wouldn't...
Hi duewy
I have altered the VB program again with some of your suggested features. I'm not a professional programmer so my ability is limited.
This version is limited.
Please test and report....
Hi duewy
Attached is an updated VB program which is a little more friendly.
This version is limited.
Please test and report.
File needs to have name extension changed to exe.
Hi duewy
Attached is a VB program which should do what you require.
This version is limited to 500 lines of code.
Please test and report.

Hi duewy Sent you a PM..
Please post about 10 lines of each code. Unmodified and modified to understand what's required.
Code G49 C120 will rotate the orientation and then run your G18 code you used for the XZ Plane
Then cancel with G49 and then G49 C240 etc.
Note this is for a Fagor controller,
Fanuc G68 does the...
You should have a space between the & and variables.
Thank you for the conversion chart. I'm old enough to be familiar with the imperial and metric system.
The OP's problem is converting fraction format (eg 13/16) to the decimal format (0.8125) when...
Hi I would look at the General Machine Parameters and determine which Axis is dedicated to your axis W. Possibly (Axis8 Label P7.)
This needs to be changed to 00. This should disable your Axis. ...
I've seen vernier callipers based on 1/128 fraction but never heard of CNC programming done in fractions.
