Tormach 1100M - Create a Tapping Sequence; Drilling and Tapping Reference; Create Threads on a Part

Create a Tapping Sequence
The Tap tab uses the G84 canned cycle — it's similar to the
G81 drill cycle, but it commands a spindle reverse once it
reaches the bottom of the hole.
Note: If you're using an auto-reversing tapping head,
use a drilling sequence. Go to "Create a Drilling
Sequence" (on the previous page).
1. In the Dwell DROfield, type the time — in seconds —
for the tool to pause at the bottom of the hole before
retracting.
A dwell gives the tool time to completely cut the bottom
of the hole.
Note: Any entry greater than 0 typed in the
Dwell DROfield replaces G81 with G82 in the
G-code — unless there is an entry greater than
0 in the Peck DROfield.
2. Set the parameters for the threads: In the Pitch
(In)DROfield or the Threads/In DROfield, type either
the required pitch or the threads per inch.
Note: The Pitch (In)DROfield and the
Threads/In DRO field are linked — after you
type a value in one and press Enter on the
keyboard, the other is auto-filled.
3. In the Conversational DROs group, make sure that the
value in the Z Feedrate DROfield is the same as the
value that you set in Step 2.
4. Set the parameters for the hole in the Zrange:
a. In the Z Start DRO field, type the location for the first
Z pass.
b. In the Z End DRO field, type the location for the last Z
pass.
Drilling and Tapping Reference
PathPilot uses the following terms when drilling and tapping
on a part in conversational programming:
l
Start Angle Specifies the angle from angle 0. Angle 0 is
a base (horizontal) line from the center point going right
(east) to the circumference. The angle from the base
line can be:
o
Positive or negative
o
Up to 90 degrees (or -90 degrees)
A negative angle produces a clockwise rotation; a
positive angle produces a counterclockwise rotation.
o
Rotates the pattern either clockwise or
counterclockwise
For example, to create a hex pattern with flats on the
top and bottom, use a value of 0 in the Start Angle
DRO field. To create a hex pattern with flats on the
left and right sides, use a value of 30 (or -30) in the
Start Angle DRO field.
l
Peck The value isn't adjusted:the G83 routine feeds at
the Z Feedrate, starting from Z Clear down to the Peck
distance, then rapid retracts to Z Clear, and rapid returns
to start the next Peck.
Note: The first and last peck will likely be
shorter than the value typed into the
PeckDROfield.
Create Threads on a Part
Using conversational programming, you can program PathPilot
to take helical tool paths around a boss or inside a hole to
create external or internal threads. For information, see
"About Thread Milling" (on the next page).
Before You Begin
Before you begin, you must verify that you enter the program
values considering the following:
l The auto-filled DROfield values assume a full-form
threaded tool. If you're using a fine-point threaded tool
to cut coarse threads, you must modify the root
diameter to account for the tool's smaller nose radius.
l The value used in the Z Clear DRO field must be such
that it can clear any blockages in the path between the
end of one Z pass and the beginning of the next.
