About NX CAM
NXTM CAM software has helped many of the world’s leading manufacturers and job shops produce better
parts faster. You can also achieve similar benefits by making use of the unique advantages NX CAM
offers.
This is one of many hands-on demonstrations designed to introduce you to the powerful capabilities in
NX CAM 10.0.2. In order to run this demonstration, you will need access to NX CAM 10.0.2.

Hands-on Demonstration: Deep Hole Drilling
Deep Hole Drilling is a new operation subtype designed to meet the special requirements of drilling deep holes. Additional Cycle Parameters allow you to control spindle behavior when engaging into the pilot hole and retracting from the deep hole as well as to control coolant when engaging, cutting, and retracting.
Control point
Top Offset distance defines minimal approach clearance plane
Rapto Offset distance defines starting plane
Engage Conditions
Cut Conditions
Retract Conditions at bottom
Retract Conditions at top
Approach move from the clearance plane to the minimal approach clearance plane.
Engage move from the minimal approach clearance plane to the starting plane.
Feed move from the starting plane to the cut depth.
Retract moves
Note: The intersection handling required for cross holes is not fully implemented in NX10.0.2. Therefore, all intersections (large and small) are treated the same and crossed with the same feed rate. This will be improved in NX10.0.3.

Prerequisites:
1. You will need access to NX CAM 10.0.2 in order to run this demonstration.
2. If you haven’t done so already, download and unzip deep_hole_drilling.7z.
Demo:
1. Open deep_hole_drilling.prt in NX.
Create the pilot hole operation
You will begin by drilling pilot holes.
1. Click Create Operation .
2. Select hole_making in the Type list.
3. Select Drilling .
4. Specify the following:
Program: DRILL
Tool: STD_DRILL_8MM
Geometry: FG_STEP1HOLE_STEP1POCKET
Method: DRILL_METHOD
5. Type PILOT in the Name box.
6. Click OK.
7. Click Specify Feature Geometry .
The pilot hole should have a depth of roughly twice the tool diameter.
8. Double-click the Depth lock icon to unlock it.
5
9. Type 16.0000 in the Depth box and press Enter.
The three features in the geometry group show the 16.0000 mm pilot hole depth.
10. Click OK in the Feature Geometry dialog box.
11. Click Generate .
12. Click Verify .
13. Select the Replay tab.
14. Set the Animation Speed to 2.
15. Click Play .
6
16. Click OK in the Tool Path Visualization dialog box.
17. Click OK in the Drilling dialog box.
Create the deep hole drilling operation
You will create a Deep Hole Drilling operation that uses the pilot holes.
1. Click Create Operation .
2. Select Deep Hole Drilling .
3. Specify the following:
Program: DRILL
Tool: GUN_DRILL_8MM
Geometry: FG_STEP1HOLE_STEP1POCKET
Method: DRILL_METHOD
4. Click OK.
5. Click Specify Feature Geometry .
There are no intersecting holes, so there is no need to specify an intersection strategy.
6. Select None from the Intersection Strategy list.
7
The Control Point parameter is new.
If Control Point is set to In-Process Feature, the tool will rapid through the pilot hole (1) as it
approaches the control point (2) located at the in-process feature. This is generally an
undesirable behavior.
If Control Point set to Machining Feature, the tool will rapid to the control point at the machining
feature (1) and then move through the pilot hole at the specified engage feed rate (2) as it
approaches the in-process feature. This is the desirable behavior in most cases.
7. Be sure Machining Feature is selected from the Control Point list.
8. Click OK to accept the feature geometry.
9. Click Feeds & Speeds .
8
10. In the Feed Rates section of the dialog box under More, type 50.0000 in the Engage box so that
the engage feed rate is 50% of the cut feed rate.
11. Click OK in the Feeds and Speeds dialog box.
When the First Cut and Last Cut options are used (default values can be found by clicking Edit
Cycle and viewing the First Cut and Last Cut values in the Cut Conditions section of the dialog
box), it is useful to specify the colors for these motions in order to clearly see each move.
Before generating the tool path, you will specify the First Cut and Last Cut display colors so you
can see each move clearly.
12. In the Options section of the dialog box, Click Edit Display .
13. Click Path Display Colors .
14. Change First Cut to White and Last Cut to Black.
15. Click OK in the Path Display Colors dialog box.
16. Click OK in the Display Options dialog box.
17. Click Generate .
18. Change the view orientation to Front.
19. Click Verify .
20. Click Step to move the tool through the path one step at a time.
9
For each hole, the tool engages through the pilot hole (1) at the specified engage feed rate (50%
cut feed rate) to the point defined by the Top Offset (2). It then continues at half the cut feed rate
as it enters the material, traveling through the First Cut move (3) to the Control Point (4). It then
deep drills (5) at the cut feed rate (250.0000 mmpm) to the Last Cut move (6) where it slows to
half the cut feed rate (this applies to through holes only) before retracting.
21. Click OK to complete the tool path visualization.
Two new Cycle options allow you to drill with or without chip breakage.
10
Deep drilling and Deep drilling with chip breakage cycles are new for Sequential Drilling and
Deep Hole Drilling operations. Deep drilling with chip breakage contains the same cycle
parameters as Deep drilling cycle, but with the additional parameters currently used for
Breakchip drilling.
22. With Deep drilling selected from the Cycle list, click Edit Cycle .
The Engage Conditions section of the Cycle Parameters dialog box is new. These options control
the coolant and spindle behavior as the tool moves through the pilot hole.
The Coolant options in the Cut Conditions section and the Spindle and Coolant options in the
Retract Conditions section of the dialog box are also new.
11
In the Retract Conditions section of the dialog box, Location specifies where to apply the spindle
and coolant retract conditions. At Bottom applies the specified spindle and coolant conditions before
retracting out of the hole. At Top applies the specified spindle and coolant conditions at the deep
drilling start plane conditions after retracting out of the hole.
Bottom Release Distance specifies how far from the hole bottom to apply the coolant and spindle retract conditions.
23. Click OK in the Cycle Parameters dialog box.
24. Click OK.
25. Click OK to finish the operation.
26. Close the part without saving.
