Answer 0

Pocketing, slotting, drilling, chamfering, boring, tapping, reaming

Question 1

Name at least 3 of the Machines used during the semester

Answer 1

Horizontal and vertical bandsaws, vertical milling machine, radial arm drill, CNC lathe, CNC vertical milling machine

Question 2

What components are on a vertical milling machine?

Answer 2

Carbide tipped face mill, or a flat end mill drill, 4 or 2 fluted, centered or not centered.

Question 3

Can you pocket with a fluted drill?

Answer 3

No

Question 4

What is boring used for?

Answer 4

For accurately sizing a hole

Question 5

How do you measure the size of a drill bit?

Answer 5

Take a vernier caliper and measure across the flats You also count the number of flutes and and if it’s centered or not.

Question 6

What two bandsaws are there in the shop?

Answer 6

Vertical and horizontal.

Question 7

What is the vertical bandsaw used for?

Answer 7

Contour cuts

Question 8

What is the horizontal bandsaw used for?

Answer 8

To cut material

Question 9

Is a radial arm drill a drill press?

Answer 9

No, because you put the material on the plate and move the drill over top of it. Arm moves on a radius.

Question 10

What does a lathe do?

Answer 10

Boring, drill, tap, mill, turn, face, cut grooves, the most universal machine because you can make another lathe using a lathe.

Question 11

How is tapering done?

Answer 11

Using either the compound method or the offset method.

Question 12

Can you use a fluted flat end for leadin/lead out?

Answer 12

Yes, you can, but cannot contour.

Question 13

What is a draw bar and how does it work?

Answer 13

A draw bar is found the vertical milling machine. You change the tool by loosening and tightening the nut at the top, and draws tool into the taper, R8 taper.

Question 14

Why should you put a shoulder in your material in the lather?

Answer 14

Because it puts less stress on the material and a lesser chance of it breaking.

Question 15

Should we let mitchell use the sand blaster?

Answer 15

Not in any circumstance, he broke it the last time he did

Question 16

How would you describe drill bits?

Answer 16

By diameter, numerically, fractional sizes.

Question 17

What is the procedure in running the vertical milling machine?

Answer 17

1) center the X and Y axis
2) turn the spindle on forwards, clockwise direction
3) set the speed, only do so when the spindle is on
4) bring the table up until it just touches, then set your 0, with the backlash up
5) bring the table up to depth to cut
6) use the hand wheels to feed throughout at a steady even pace

Question 18

What is the procedure for end facing on the lathe?

Answer 18

1) set the speed, then turn the machine on
2) move it so that it just touches, so that it runs true using the cross slide axis hand wheel
3) then move it out to the outside at a steady, even pace
4) if necessary, check the edge for burs then using a file, left handedly bevel the edge

Question 19

What tool is on the lathe?

Answer 19

Facing and turning tool made of high speed steel, (HSS)

Question 20

What is the procedure for turning a diameter on the lathe?

Answer 20

1) set speed then turn the machine on
2) using the cross slide axis hand wheel to just touch to make sure that it’s running true
3) then move it to the outside at a steady, even pace
4) set the depth, then go in

Question 21

When turning a diameter on the lathe, if you set the depth for .05, will it take off only .05?

Answer 21

No, it will actually be .10, because the turning tool will take the .05 off both sides

Question 22

What is the design process?

Answer 22

1) Idea
2) Research
3) Design
4) Production
5) Test and evaluation

Question 23

What are the three types of tap drills?

Answer 23

NC (national course) NF (national fine) NPT (national (I forget, it’s in the textbook))
