Illegal modal (mill)

Details
The milling mode was turned ON during nose R compensation or constant surface speed control.
A T command was issued during the milling mode.
The mode was switched from milling to cutting during tool compensation.
Cylindrical interpolation or polar coordinate interpolation was commanded during the constant surface
speed control mode (G96).
The command unacceptable in the cylindrical interpolation was issued.
A T command was issued during the cylindrical interpolation or polar coordinate interpolation mode.
A movement command was issued when the plane was not selected just before or after the G07.1 com-
mand.
A plane selection command was issued during the polar coordinate interpolation mode.
Cylindrical interpolation or polar coordinate interpolation was commanded during tool radius compensa-
tion.
The G16 plane in which the radius value of a cylinder is "0" was specified.
A cylindrical interpolation or polar coordinate interpolation command was issued during coordinate rotation
by program.
Remedy
Correct the program.
Issue G40 or G97 before issuing G12.1.
Issue a T command before issuing G12.1.
Issue G40 before issuing G13.1.
Specify the radius value of a cylinder other than "0", or specify the X axis's current value other than "0"
before issuing G12.1/G16.

Milling error

Details
The milling command was issued during the mirror image (when parameter or external input is turned ON).
Polar coordinate interpolation, cylindrical interpolation or milling interpolation was commanded during mir-
ror image for facing tool posts.
The start command of the cylindrical interpolation or polar coordinate interpolation was issued during the
normal line control.
Remedy
Correct the program.
