Need Help!- to do profile in X,Z plane..???

[volvomech]

hi..

i'm using horizontal boring machine which is controlled by 840D..

i want to cut a profile in a X,Z plane.. starting point is Z=0,X=0 end point is Z=-25,X=-30 between start to end point i have to make one R20 radius profile..!! is this possible in horizontal boring machine..

i d'nt have universal head..

if it is in X,Y plane i can use G02 or G03.. but for X,Z plane, any code is there..??

or i have to use some other codes..?? please help me...

You just need to change your PLANE select.
Normally, you work in the G17 (X,Y & I,J) plane ... you need to use a G18 (X,Z & I, K) plane.
Program like you would normally but, instead of arc centers as I, J use I and K.

Try one out in MDI first ... and remember - ALWAYS SWITCH BACK to your G17 plane when you're done!

Hello,

You need to set up the working plane for X/Y arcs the default is already active G17, for the others you'll need to program it before the radius as follow:

G17 ; SELECTION OF XY PLANE (milling / wiring EDM / boring machines default)
G02 / G03 X Y I J

G18 ; SELECTION OF XZ PLANE (turning / grinders machines default)
G02 / G03 X Z I K

G19 ; SELECTION OF YZ PLANE
G02 / G03 Y Z J K

The arc centers I, J and K on SINUMERIK can be programed considering the last point or the absolute position with eg. I=AC(absolute arc center position).

I hope that it helps,
Eduardo

Also be aware that although G18 is often called and documented as the XZ plane it is actually the ZX plane (on almost all controls). It can be very confusing. Test it out before cutting anything for real.

i tried,bt it says K is programmed to often...

if i.m correcting K.. the cycle is not working..!!

Possibly you have specified both radius and center (I, K) which your control may not be accepting.

Are you looking at programs which can be run like being run using a right angle head ?

If yes then post the code to do this operation in 3 axis (normal tool axis in Z axis) or send me a message with the code and i can convert it and send it back to you. i have developed an app which switches axis from Z to X or Z to Y including the circular interpolation commands with I,J and K.
