"G70.03 Circular Dowel (Metric Mode)" Dialog Box

• Orientation (G): The cutting orientation can be clockwise (CW, G02) or counterclockwise (CCW , G03).
• Step In Axis (P): can be Not Defined, + 1st Axis, + 2nd Axis, - 1st Axis, and - 2nd Axis, which will be shown as P0~P4 command in the program. The orientation of 1st axis and 2nd axis are depends on the working plane (G17/G18/G19).

• Center X/Y/Z: center of dowel machining. It can be absolute positions or incremental values.

• Dowel Radius (R value): the radius of inner circle.
• U/V/W Depth (U value): the depth of the dowel. The value is negative.
• Perimeter Radius (A value): the radius of perimeter circle.
• Perimeter Radius (A value) must be greater than Dowel Radius (R value).
• Clearance (C value): the safe starting height for machining.

• Fine Feed Width (J value) and Fine Feed Depth (K value): the width and depth of fine cut.
• Step In Depth (Q value): the depth being machined per layer.

• Spindle Feed Rate (I value): feed rate of spindle. Please refer to INCON-M84/M86/M86R Integration Manual for more information.
• Fine Feed Rate (E value): feed rate of fine cutting. If the value of Fine Feed Rate (E value) was left blank, system will replace the value with half of Feed Rate (F value) value.
• Feed Rate (F value): the velocity at which the cutter is fed, the system will adopt the value set last time if users do not make any changes.

• Users need to set the number of tool table (D_) and the tool radius before processing dowel machining.
