19.4.7 Operation with 45º spindles (Huron type).
Huron type spindles have two solutions for orienting the tool perpendicular to the new work
plane.
• The first solution is the one that involves the smallest movement of the main rotary axis
(the articulation closest to the ram or furthest away from the tool) referred to the zero
position.
• The second solution is the one that involves the largest movement of the main rotary axis
referred to the zero position.
The selected solution will be applied to calculate the offsets of the spindle and for the
instruction #TOOL ORI, placing the tool perpendicular to the work plane. See "19.5 Tool
perpendicular to the inclined plane (#TOOL ORI)." on page 338.
Selecting one of the solutions to orient the spindle.
When defining a new coordinate system, it is possible to select which one of the two solutions
to be applied. For this type of spindles, if the command SOL2 is programmed together with
the instruction #CS or #ACS, the CNC applies the second solution; otherwise, if nothing is
programmed, the CNC applies the first solution.

Consulting the position for each axis to occupy.
The position for each rotary axis to be perpendicular to the inclined plane may be consulted
in the following variables. The CNC updates these variables every time a new plane is
selected, using the instruction #CS or #ACS.
Variables for the first solution.
Variables for the second solution.
Variables. Meaning.
V.G.TOOLORIF1 Position (machine coordinates) of the first rotary axis.
V.G.TOOLORIS1 Position (machine coordinates) of the second rotary axis.
V.G.TOOLORIT1 Position (machine coordinates) of the third rotary axis.
V.G.TOOLORIO1 Position (machine coordinates) of the fourth rotary axis.
Variables. Meaning.
V.G.TOOLORIF2 Position (machine coordinates) of the first rotary axis.
V.G.TOOLORIS2 Position (machine coordinates) of the second rotary axis.
V.G.TOOLORIT2 Position (machine coordinates) of the third rotary axis.
V.G.TOOLORIO2 Position (machine coordinates) of the fourth rotary axis.
