NC Codes dialog (Wire)

Specifies the exact character strings for different NC commands. The NC Codes dialog appears.

You can specify the following parameters:

Motions — The options in this section describe motion types required by the NC machine. All of these codes must be specified.

For example, Linear is generally defined as G1, but may be changed to G01, or any other string (up to 11 characters). All motion commands are passed to Post via the string reserved word <MOTION>.

The following options are available:

• Rapid — rapid move.
• Linear — feed move.
• Circ. CW — circular interpolation, clockwise.
• Circ. CCW — circular interpolation, counter-clockwise.
• XY, UV — refers to Wire EDM 4-axis movements using an upper and a lower curve. Typically, XY represents the curve at the bottom of the part, and UV represents the curve at the top of the part.
Note: This option is only available for wire EDM posts.

Compensation — This generates cutter diameter compensation in the output when enabled in FeatureCAM, and if it is built into the CNC data file.

Units — Specify the G codes that set the post to Inch Units or Metric Units. The reserved word <UNITS> outputs the current value specified by the user. Typical values are G20/G21 or G70/G71.

Taper — This generates wire taper in the output when Left or Right is selected in FeatureCAM, and built into the CNC build file.

The reserved word <TAP-STAT> is assigned to one of these strings. The most common commands for taper cutting are assigned below. Of course there may be other strings as well, depending on the type of control.

• Cancel — G50.
• Left — G51.
• Right — G52.
