Ramping into a Compensation Move

Entry moves allow a smooth transition into a contour. Allowing a way to avoid areas you do not want to affect with the tool when entering a contour, Entry Move button (G36). If an entry move without compensation is required, program a tool with “0” radius.

Four types of entry moves are available. Refer to Line Tangent Entry Move, Line Perpendicular Entry Move, Arc Tangent Entry Move and Line Arc Tangent Entry Move.

Line Tangent Entry Move

In a line tangent entry move the tool approaches the contour in a line move tangent to the first move of the contour.

The tool feeds from the current position to a calculated point based on the Length (L) parameter then feeds to the compensated starting point of the contour in a line move tangent to the first move of the contour. The direction of the entry move can be reversed by programming a negative Length (L). All programmed Z movements occur during the entry move (G41 Xx Yy Zz G36 Q1 Ll).

The line tangent exit move is executed the same as the entry, but in reverse order (G37 Q1 Ll).

Line Perpendicular Entry Move

In a line perpendicular entry move the tool approaches the contour in a line move perpendicular to the first move of the contour.

The tool feeds from the current position to a calculated point based on the Length (L) parameter then feeds to the compensated starting point of the contour in a line move perpendicular to the first move of the contour. The direction of the entry move can be reversed by programming a negative Length (L). All programmed Z movements occur during the entry move (G41 Xx Yy Zz G36 Q2 Ll).

The line perpendicular exit move is executed the same as the entry, but in reverse order (G37 Q2 Ll).
