F - Feed Rate per revolution (G99)
U - X-Axis incremental distance
S - RPM, called prior to G195
X - Position of the X Axis at the bottom of hole
Z - Z-Axis position before drilling

The tool must be positioned to the start point before commanding G195/G196. This G code is called for each hole being tapped. The cycle begins from the current position, tapping to the X-axis depth specified. An R plane is not used. Only X and F values should be used on G195/G196 lines. The tool must be positioned to the start point of any additional holes before commanding G195/G196 again.

S RPM should be called out as a positive number. It is not necessary to start the spindle in the correct direction; the control does this automatically.

G195/G196 Live Tooling Rigid Tapping: [1] Rapid, [2] Feed, [3] Start or end of stroke, [4] Starting point, [5] Part surface, [6] Bottom of the hole, [7] Centerline.
