M-Series Operator’s Manual 4/9/2015 10-23
Spindle Direction: Shows the current spindle direction. The spindle direction should be CW for right-hand tapping,
and CCW for left-hand tapping. The spindle speed and direction appropriate for the tapping tool should be set in the
tool change in which the tapping tool was loaded. This field will be hidden if a reversing tap head is used.
* WARNING: The tap must be rotating in the correct direction before performing this operation.
Position: Specifies the X and Y coordinates where the tapping will take place. If either the X or Y coordinate is an
incremental value, you will have the option to tap multiple holes in a linear pattern. (See Canned Cycle Introduction
#2)
Surface Height: Absolute Z-axis position from where each incremental depth is measured.
Clearance Height: This parameter specifies the Z-axis height used when performing rapid moves to the position of
each hole being drilled.
'Rapid To' Depth: The depth to which the cutter rapid moves before beginning to drill the hole at the specified Plunge
Rate. This is below the Clearance Height but above the Surface Height.
Depth Total: Depth of hole (incremental) as measured from Surface Height.
Depth Increment: (available only on rigid tapping.) This sets the length of each progressive "peck" down the hole.
Threads / Unit: Number of threads on each inch/mm of the tap. Used in conjunction with the Spindle Speed to
calculate the appropriate plunge rate (Plunge Rate = Spindle Speed / Threads per Unit).
Spindle Speed: Rate at which the spindle rotates. Used in conjunction with the Threads / Unit to calculate the plunge
rate.
* WARNING: The spindle speed must be set before performing this operation.
Dwell Time: Delay at bottom of hole before starting ascent. This is used for a floating tap to allow the spindle time to
reverse direction at the bottom of the hole. A default value of 0.1 seconds is suggested. This field will be hidden if a
reversing tap head is used; the tap head will reverse direction when the quill begins ascending.
* NOTE: When using low gear for tapping, the spindle may turn opposite the direction specified. The operator is
responsible for setting the correct spindle speed and direction.
