Gentlemen,
    I have an opportunity for a commercial installation of EMC. This
would be on a Cincinnati 5 axis C frame mill. It is a 20V. I think it
is a 120. The 120 is the X travel in inches.
    I will implement a tool length setting routine. I believe it can
be easily implemented in AXIS. This would be fine but I think it would
be better if it was usable in all choices of control displays.
    At what level would it be implemented to be usable by all choices
of control displays?
    The tool length protocol would be like this:

A register would hold a number representing the distance between the
XY table surface and the gage point of the taper in the spindle at Z
home position.
The AB axes would be positioned at A0.0 B0.0.
The Z axis would be lowered until the tool tip touches the XY table surface.
A button on the control would be pushed.
The control would write the difference between 1: the distance from
the gage point and XY table  and 2: the distance of the current
position from Z home position.

    This would result in a positive tool length offset value.
    This would allow an offline tool length determination to be
written to the tool table prior to the tool loaded into the spindle.
The same number would be the result using the machine or the offline
tool.
    This would allow 5 axis tool length compensation.

    Any and all thoughts and comments are welcome.
thanks
Stuart
