Acu-Rite CNC 3500i user manual Line Arc Tangent Entry Move

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

(G41 Xx Yy Zz G36 Q3 Rr Cc).

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).
