Q

The first machining step in milling a T-slot is to mill

A 45-degree angle in the groove
A chamfer at the top of the slot
A slot or groove in the workpiece
The “T” in the slot

A

A slot or groove in the workpiece

22
Q

In a horizontal setup, what kind of cutter is used to mill the vertical slot?

End mill
Face mill
Shell end mill
Side mill

23
Q

To align the cutter exactly over the top of the intended slot, you must subtract half the cutter width from the

Distance across the end of the workpiece
Distance between the slot and the end of the workpiece
Distance between the slots, centerline and the workpiece edge
Width of the workpiece

A

Distance between the slots centerline and the workpiece edge

24
Q

You can fit a T – slot cutter into the horizontal spindle by using a(n)

26
To bevel the edge of a work piece in a horizontal set up, what kind of cutter is used? End mill Face mill Single-angle mill Slab mill
Single-angle mill
27
What kind of cutter is used to mill a slot in a vertical set up? End mill Face mill Half side mill Side mill
End mill
28
When milling a T – slot with a vertical set up as compared with a horizontal set up, you should use A heavier T – slot cutter A longer T – slot cutter A shorter T-slot cutter The same T – slot cutter
The same T – slot cutter
29
To angle mill a workpiece in a vertical setup, what kind of cutter would you use ? End mill Face mill Side mill Slab mill

31
In straddle milling, the distance between the cuts is controlled by the Spacers between the cutters Table travel Transverse adjustment Vertical feed
Spacers between the cutters
32
In straddle milling, there must be adequate clearance between the work piece and the Column Knee Spacers Spindle

33
The greatest advantage in a straddle milling is that you? Achieve a deeper cut Get a better finished surface Get greater power Save time
Save time
34
In straddle milling, in order to balance the thrust load on the arbor, the half side milling cutters should have Diameter of less than two inches More than 3 in. of distance between them Opposite helixes Staggered teeth
Opposite helixes
35
The cutter used to mill an angled step must be wide enough to Cut the full depth of the step Cut the full length of the step Cut the wide end of the step Straddle mill the step

36
Which of the following is the most precise method of finding out how wide the end of an angled step measures? Compass and scale Scale drawing Surface gauge Trigonometry
Trigonometry
37
When you select a cutter for an angled step, you should always select the smallest cutter that will cut the wide end of the step because it Cuts deeper Gives a finer cut Is less expensive Last longer
Is less expensive
38
When milling a step on a workpiece that is mounted at an angle, you must advance the crossfeed an amount that is _______ the desired width of the step (measured on the workpiece). Less than Equal to More than Not related to
Less than
39
What kind of an arbor is used for Shell end mill? Style A Style B Style C Style D
