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 (i.e. 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. Se。
