4.2 Tool Data
Arc Tangent Entry Move
In an arc tangent entry move the tool approaches the contour through
an arc and enters tangent to the first move of the contour.
The tool feeds from the current position to a calculated point based on
the Angle (C) and Radius (R) then feeds through an arc and into the
contour tangent to the first move of the contour. To create an arc
tangent in the opposite direction, use a negative Radius (R). All
programmed Z movements occur during the entry move
(G41XxYyZzG36Q3RrCc).
The arc tangent exit move is executed the same as the entry, but in
reverse order (G37 Q3 Rr Cc).
Line Arc Tangent Entry Move
In a line arc tangent entry move the tool approaches the contour
through an arc and enters tangent to the first move of the contour.
The tool feeds from the current position to a calculated point based on
being tangent to an arc of a given Radius (R) then feeds through the
arc to the compensated starting point of the contour and enters the
contour tangent to the first move of the contour. To create an arc
tangent in the opposite direction, use a negative Radius (R). All
programmed Z movements occur during the entry move (G41 Xx Yy
Zz G36 Q4 Rr).
The line arc tangent exit move is executed the same as the entry, but
in reverse order (G37 Q4 Rr Xx Yy Zz).
