6. Face Cutting Fixed Cycle, G94
Format:
G94 X(U)____Z(W) ____R____F____
R : The difference between point B and C in radius.
X, Z, U, W and F are identical to those of the linear traversed canned cycle.
Fig. 3-30 G94 Tapered Traversed Cutting Path
When using incremental coordinates, the signs (+/-) of U and W are determined by the
tool's moving directions. If the moving direction is positive, the increment of U and W
is (+), and vice versa. R value is as Fig. 3-31.

Note that G90, G94, G92 are modal codes and all the values for X(U), Z(W) and R
remain valid unless they are redefined or another G-command is given.
As shown in Fig. 3-32, if the length of movement on Z-axis is fixed, the canned cycle is
repeated merely by executing the X-axis positioning command.
