FANUC Series 30i-MODEL A
Tool center point control
for 5-axis machining
Ed. Date Design Description
Date Jan.16.’04 Design. Apprv.
Because the specified speed is usually the speed in the tangent direction of
the arc, the speed of the linear axis, when seen from the table coordinate
system, is:
arc theofLength
axislinear theofLength
×F .
Depending on parameter HTG (No.1403#5), the specified speed varies as
shown in the following table.
HTG (No.1403#5)
0 1
Tangential speed of the arc
Synthetic speed of the linear axis
speed and tangential speed
While performing compensation for the rotary axes, the CNC controls the
control points so that the tool center point moves helically with respect to the
table (workpiece). The end of the tool center point comes to the point
specified on the programming coordinate system.
CAUTION
Any command that does not move the tool center
point with respect to the workpiece (one that moves
the rotary axes only) must be executed in G00 or
G01 mode.
