Fig. 22.2 (h) Actual Speed Indication during Circular Interpolation
(1) In any of the following G code modes, cylindrical interpolation
cutting point compensation can be specified:
G17,G18,G19 : Plane selection
G22 : Stored stroke check function on
G64 : Cutting mode
G90,G91 : Absolute command programming, incremental
command programming
G94 : Feed per minute
(2) Any of the following G codes can be specified in cylindrical
interpolation cutting point compensation mode:
G01,G02 ,G03 : Linear interpolation, circular interpolation
G04 : Dwell
G40,G41,G42 : Cutter compensation
G40.1–G42. : Normal direction control
G64 : Cutting mode
G65–G67 : Macro call
G90,G91 : Absolute command programming, incremental
command programming
Set to use this function as parameter CYA (No.19530#5)=1.
Theoretically, when the inner area of a corner is cut using linear
interpolation as shown in Fig. 22.2 (i), this function slightly overcuts the
inner walls of the corner. This overcutting can be avoided by specifying
a value of R that is slightly greater than the radius of the tool at the corner.
