and the feedrate along the arc(the tangential feedrate of the arc) is controlled to be the specified
feedrate.
The error between the specified feedrate and the actual tool feedrate is ±2% or less. However,
this feed rate is measured along the arc after the cutter compensation is applied.
Note: 1.When I = 0 , J = 0 or K = 0, they can be omitted; one of I, K or R must be input, otherwise the
system alarms.
2.If I,J,K, and R addresses are specified simultaneously, the arc specified by address R takes precedence
and the other are ignored.
3.Processing arc workpiece usually use ball tool(arc tool) in the actual process, it must use function of
tool radius compensation in programming, that's G41 G42 instruction.
4.Arc path can be more than and less than 180° when R is commanded, the arc is more than180° when R
is negative, and it is less than or equal to 180
°
when R is positive.
5.If an axis not comprising the specified plane is commanded, an alarm is displayed.
6.When an arc having a center angle approaching 180º is specified, the calculated center coordinates may
contain an error. In such a case,specify the center of the arc with I,J,and K.
Example:
The above tool path can be programmed as follows:
(1) In absolute programming
G92 X200.0 Y40.0 Z0 ;
G90 G03 X140.0 Y100.0 R60.0 F300.;
G02 X120.0 Y60.0 R50.0 ;
Or
