RTCP Pivot Offset Problem

I had posted this topic in the Machines/Control area few days back. But didn't recieve any reply. So trying my luck here.

-------------------------------------------------------------------------------------

This is a Mill-Turn Machine with a B axis Tool changer.
The Pivot offset is given for the tool tip and the right macros (TurnOnOffGagePivotOffset, TurnOnOffGageOffset & SetgageOffset) are employed to counter the B axis positioning.
When X, Y, Z & B axes are commanded to a position in a single block the tool head moves to a position which is not yet updated with the tool pivot offsets.
When the same block is executed again the tool head is positioned correctly (with the tool pivot offsets updated).
This is happening when B is positioned for the first time with X, Z axes. Later any amount of time I call the X, Z, Y & B together it seems to work fine.

Kindly suggest how to correct this discrepancy.

Re: RTCP Pivot Offset Problem

I think you might want to setup the B Axis motion to process before the gage offset is updated.

I have a rotary 2 axis head with another rotary table and this is how I had to format it to get the right tool motion. It took a long time to figure that one out..

from .ctl file

B*.*

MACRO "TurnOnOffGageOffset" {
OVERRIDE_VALUE 0
}
MACRO "ToolLengthCompOff"
MACRO "TurnOnOffGagePivotOffset" {
OVERRIDE_VALUE 0
}               
MACRO "BAxisMotion"
MACRO "ProcessMotion"
MACRO "TurnOnOffGagePivotOffset" {
OVERRIDE_VALUE 1
