# --------------------------------------------------------------------------# Features:

# --------------------------------------------------------------------------# This post supports Generic Fanuc code output for 3 and 4 axis milling.

# It is designed to support the features of Mastercam Mill V9.

#

# Following Misc. Integers are used:

#

# mi1 - Work coordinate system

# 0 = Reference return is generated and G92 with the

# X, Y and Z home positions at file head.

# 1 = Reference return is generated and G92 with the

# X, Y and Z home positions at each tool.

# 2 = WCS of G54, G55.... based on Mastercam settings.

#

# mi2 - Absolute or Incremental positioning at top level

# 0 = absolute

# 1 = incremental

#

# mi3 - Select G28 or G30 reference point return.

# 0 = G28, 1 = G30

#

#Canned text:

# Entering cantext on a contour point from within Mastercam allows the # following functions to enable/disable.

# Cantext value:

# 1 = Stop = output the "M00" stop code

# 2 = Ostop = output the "M01" optional stop code

# 3 = Bld on = turn on block delete codes in NC lines

# 4 = bLd off = turn off block delete codes in NC lines

#

#Milling toolpaths (4 axis)

#Layout:

# The term "Reference View" refers to the coordinate system associated

# with the Top view (Alt-F9, the upper gnomon of the three displayed).

# Create the part drawing with the axis of rotation about the axis

# of the "Reference View" according to the setting you entered for

# 'vmc' (vertical or horizontal) and 'rot_on_x' (machine relative

# axis of rotation).

# vmc = 1 (vertical machine) uses the top toolplane as the base machine

# view.

# vmc = 0 (horizontal machine) uses the front toolplane as the base machine # view.

# Relative to the machine matrix -

# Rotation zero position is on the Z axis for rotation on X axis.

# Rotation zero position is on the Z axis for rotation on Y axis.

# Rotation zero position is on the X axis for rotation on Z axis.

# The machine view rotated about the selected axis as a "single axis

# rotation" are the only legal views for 4 axis milling. Rotation

# direction around the part is positive in the CCW direction when

# viewed from the plus direction of the rotating axis. Set the variable

# 'rot_ccw_pos' to indicate the signed direction. Always set the work

# origin at the center of rotation.

#

#Toolplane Positioning:

# Create the Cplane and Tplane as the rotation of the machine view about

# the selected axis of rotation. The toolplane is used to calculate

# the position of the rotary axis. This is the default setting.

#

#3 Axis Rotary (Polar)

# Polar positioning is offered in Mastercam 3 axis toolpaths through the

# rotary axis options dialog. The selected toolpath is converted to angle # and radius position. The axis of rotation is forced to zero.

#

#Axis substitution:

# Use the Rotary axis substitution by drawing the geometry flattened

# from the cylinder. The rotary axis button must be active for axis

# substitution information to be output to the NCI file. The radius of

# the rotary diameter is added to all the Z positions at output.

#

#Simultaneous 4 Axis (11 gcode):

# Full 4 axis toolpaths can be generated from various toolpaths under the

# 'multi-axis' selection . Rotary 4 axis). All 5 axis paths are

# converted to 4 axis paths where only the angle about the rotation axis

# is resolved.

#

#Drill:

# All drill methods are supported in the post. See Simultaneous 4 Axis.

#

#Additional Notes:

# 1) Disable 4 axis by setting the numbered question 164. to 'n'.

# 2) G54 calls are generated where the work offset entry of 0 = G54,

# 1 = G55, etc.

# 3) Metric is applied from the NCI met_tool variable.

# 4) Incremental mode calculates motion from home position at toolchanges. # The home position is used to define the last position of the tool

# for all toolchanges.

# 5) The variable 'absinc' is now pre-defined, set mi2 (Misc. Integer) for # the 'top level' absolute/incremental program output. Subprograms are # updated through the Mastercam dialog settings for sub-programs.

# 6) Always avoid machining to the center of rotation with rotary axis!

# 7) Transform subprograms are intended for use with G54.. workshifts.
