Note 1: When the system is turned on or resets, the polar coordinate interpolation is cancelled(G13.1);
G12.1 and G13.1 are modal;
Note 2: The linear axis and turn axis for the polar coordinate interpolation must be set in advance in
NO.5460, NO.5461; the axis undefined by the parameter does not execute the polar coordinate
interpolation in spite of specifying the movement value in the polar coordinate interpolation mode;
Note 3: The used level (selected by G17, G18 or G19) before G12.1 is cancelled; after G13.1 cancels the
polar coordinate interpolation, the level recovers; when the system resets, the polar coordinate
interpolation is cancelled and the system uses the level selected by G17, G18 or G19;
Note 4: In the polar coordinate interpolation mode, the program commands use the rectangular coordinate
command in the polar coordinate level. The linear axis in the level uses the diameter or radius
programming and the turn axis uses the radius programming;
Note 5: G codes in the polar coordinate interpolation mode can be used as follows:
G01
:
linear interpolation;
G02, G03
:
arc interpolation;
G04
:
dwell;
G40, G41, G42
:
tool nose radius compensation;
G65, G66, G67
:
user macro program command;
G98, G99
:
feed/rev, feed/minute;
The system alarms when other G commands are executed in the polar coordinate
interpolation mode.
Note 6: F feedrate is the tangent speed with the polar coordinate interpolation level(rectangular coordinate
system) in the polar coordinate interpolation mode;
Note 7: The arc interpolation commanding the arc radius address is determined by the linear axis of the
interpolation level in the polar coordinate interpolation level as follows:
Use I and J when the linear axis is X or its parallel and the turn axis uses J;
Use J and K when the linear axis is X or its parallel and the turn axis uses J;
Use K and I when the linear axis is Z or its parallel and the turn axis uses I;
Note 8: Must set a workpiece coordinate system before using G12.1, the center of the turn axis is the
origin of the coordinate system. The coordinate system must not be changed in G12.1 mode.
Note 9: Cannot start or cancel the polar coordinate interpolation mode; command G12.1 or G13.1 in G40;
otherwise, the system alarms;
Note 10: When the tool traverses near to the workpiece center in the polar coordinate interpolation mode,
C weight of feedrate changes, which exceeds max. C cutting speed to cause the system alarms.
Note 11: The program command uses the rectangular coordinate command in the polar coordinate level.
The axis address of the turn axis is taken as the one of the 2
nd
axis(imaginary axis) in the level.
When the system executes G12.1, the tool position of the polar coordinate interpolation starts
