While the In-Position Mode (G61) is active, the CNC approaches target
and performs an in-position check before the next move is executed. The
CNC comes to a complete stop at the completion of each command. This
could cause tool dwell marks to appear on the workpiece, but prevents
the CNC from rounding off sharp corners.
NOTE: The In-Position and Continuous Path Tolerances are defined in
the Setup Utility. The In-Position Tolerance should be closer to
target than the Continuous Path Tolerance.
G61 is modal and remains in effect until canceled. Use Contouring Mode
(G61) to cancel the In-Position Mode. Use G9 (Non-modal In-Position
Mode) to apply the In-Position Mode to a single block.
Contouring Mode (Cutting Mode) (G64)
Refer to Table 4-18.
Table 4-18, G64 and Associated G-Codes
Code Format Action
G9
G9 Xx.x Zx.x Activates non-modal In-Position Mode.
Complete stop only in this block.
G64
G64 Activates the Contouring Mode (also
called Continuous Path Mode). The
CNC approaches target and comes
within the Continuous Path Tolerance of
the target position. No in-position check
is made.
G61
G61 Xx.x Zx.x Cancels G64 and activates the In-
Position Mode.
Format: G64
NOTE: Rapid moves always execute in In-Position Mode.
The Contouring Mode (G64), also known as Continuous Path Mode, or
Cutting Mode, is active at power ON. It is used for feed moves. With the
Contouring Mode activated, the CNC approaches target and comes within
the Continuous Path Tolerance of the target position. No in-position
check is made before the next move is executed. (During an in-position
check, the CNC comes to a stop within the in-position tolerance of the
target position.) This enables smooth contouring of a profile or surface.
NOTE: The machine builder defines the in-position and continuous path
tolerances in the Setup Utility.
G64 is modal and remains in effect until canceled. Use Exact Stop Check
(G61) to cancel the Contouring Mode. G64 initiates linear (G1) or circular
interpolation (G2, G3).
