G94 End Facing Cycle (Group 01)

F(E) - Feed rate
*K - Optional distance and direction of Z Axis coning
*U - X-axis incremental distance to target, diameter
*W - Z-axis incremental distance to target
X - X-axis absolute location of target
Z - Z-axis absolute location of target

*indicates optional

G94 End Facing Cycle: [1] Rapid, [2] Feed, [3] Programmed path, [4] Cut allowance, [5] Finish allowance, [6] Start position, [7] Target.

Straight end facing cuts can be made by specifying X, Z and F. By adding K a cone-shaped face is cut. The amount of coning is referenced from the target. That is K is added to the value of X at the target.

Any of the four ZX quadrants is programmed by varying U, W, X, and Z. The coning is positive or negative. The following figure gives a few examples of the values required for machining in each of the four quadrants.

During incremental programming, the sign of the number following the U and W variables depends on the direction of the tool path. If the direction of a path along the X-axis is negative, the value of U is negative.

G94 Address Relationships: [S] Start position.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.
