U
V
W
In the absolute code, values specified in the address X,Y,Z and R are taken as the offsetvalue
corresponded to the offset number specified by P.
In the incremental code, values specified in the address X,Y,Z and R should be added to the
current offset value corresponding to the offset number.
Note 1: X, Y, Z, U, V and W are specified in the same block.
Note 2: Using the code in a program can permit the tool to feed point by point. Also, using the code can
input an offset value one at a time from continuously specifying the code's program instead of
inputting these offset value one at a time from MDI mode.

2.9 Polar Coordinate Interpolation G12.1, G13.1

Command function: the contour is controlled by the programming code in the rectangle
coordinate system being switched into one linear motion (tool motion) and one turn
motion (workpiece turn motion). The function is used to end face cutting.
Command format: G12.1; enter the polar coordinate interpolation mode, also be written to G112;

G13.1; cancel the polar coordinate interpolation mode, also be written to G113;
Command explanation: G12.1, G13.1, are specified by an single block.
Before executing the polar coordinate interpolation, the system must firstly set a linear axis
androtary axis performing the polar coordinate interpolation by NO.5460, NO.5461. The polar
coordinate interpolation plane consists of a linear axis and a rotary axis, and the polar coordinate
interpolation is performed in the plane, which is shown in Fig. 2-11.
 
Chapter 2 G Commands
Description
The code value is an offset number
P = 1~99 :the tool wear offset value code
P = 10001~10099 :the tool geometry offset value code
X offset value (absolute);
Y offset value (incremental);
Z offset value (absolute);
X offset value (absolute);
Y offset value (incremental);
Z offset value (incremental);
The following commands can be commanded in polar coordinate
interpolation mode:
G01:linear inerpolation;
G02, G03:circular interpolation;
G04:dewell ;
G40, G41, G42:tool nose radius compensation;
G65, G66, G67:user macro program command;
G98, G99:feed per rev, feed per minute;
