3. INTERPOLATION FUNCTIONS
NC FUNCTION
41
When the form on the expanded side view of a cylinder (from on the
cylinder coordinate system) is commanded by a program command, the
NC converts the form into a linear axis movement and a rotary axis
movement then performs a contour control. This feature is called the
cylindrical interpolation.
Cylindrical interpolation is commanded with G07.1.
G07.1 (Name of rotary axis) Radius value of cylinder ;
Cylindrical interpolation mode
G07.1 (Name of rotary axis) 0 ;
Cancellation mode of cylindrical interpolation
Cylindrical interpolation is made between the rotary axis specified in the
block of G07.1 and the other optional linear axis.
Circle interpolation command is allowed as well as linear interpolation,
during cylindrical interpolation mode. Also, absolute command and
incremental command can be made. Cutter compensation can be added
to the program command. Cylindrical interpolation is made for the path
after cutter compensation.
Feed rate gives the tangential speed on the expanded plane of the cylinder
with F.
G07.1 (Name of rotary axis) 0; Cancellation mode of cylindrical
interpolation is made when commanded as above.
