M-Series Operator’s Manual 4/9/2015 10-11
Angle: Number of degrees through which the cutter will travel. This value must lie between 0 and 360 degrees. You
will be able to edit this field only if you are specifying a center point and angle (CP&A) arc.
Radius: Distance from the center of the arc to its edge. This value must be greater than 0. You will only be able to
edit this value if you are specifying an end point and radius (EP&R) arc.
Plane: This determines whether the arc is to be milled in the XY-, ZX- or YZ-plane. If any of the Z coordinate values
are tied to the Z home position, only XY-plane arcs may be selected.
Direction: Determines whether the arc moves clockwise (CW) or counterclockwise (CCW). Note that the direction of
XZ arcs is judged looking Y+ (i.e. from the front of the machine). This is natural, but it is opposite of the way arcs are
specified in G codes. Intercon automatically makes this translation when it generates CNC codes.
Connect Radius: This field works like the Linear Mill connect radius. It allows for the blending of an arc into the next
line or arc operation.
Feedrate: Speed at which the cutter moves.
The feedrate can be toggled to modal, fixed or slave, this is indicated by the symbol beside the feedrate field. If the
feedrate is modal then it will have the “M” symbol or if it is fixed it will have the “F” symbol shown below. The slave
feedrate has no symbol and is set to the last modal feedrate set in the program, when the modal feedrate changes all the
following slave feedrates change until the next modal feedrate is encountered.
Angle <= 180º: For end point and radius (EP&R) arcs, this field determines whether the arc is to be less than (YES) or
greater than (NO) 180 degrees.
