common operations

Question 1

operations:

Answer 1

1) turning
2) facing
3) threading
4) grooving
5) parting/cutoff
6) drilling
7) reaming
8) boring
9) tapping

Question 2

turning

Answer 2

tool is fed linearly \ to axis of rotation = reduce diameter

Question 3

facing

Answer 3

tool is fed radially = flat surface

Question 4

threading

Answer 4

pointed tool is fed linearly \ to axis of rotation across outside of surface of workpiece; faster feedrate = produce spiral thread around workpiece

Question 5

grooving

Answer 5

straight edged tool is fed radially into workpiece to a specified depth

Question 6

parting/cutoff

Answer 6

tool is fed radially into workpiece to centre of workpiece = cut off part at specific length

Question 7

drilling

Answer 7

drill bit is fed into centre of rotating workpiece on one end = hole

Question 8

reaming

Answer 8

reamer is fed into centre of workpiece on one end = hole w/ specific finish, size & tolerance

drilling must be done first

Question 9

boring

Answer 9

single point cutting tool is fed linearly \ to axis of rotation on inside diameter of existing hole in workpiece;
care = ensure existing hole is larger than boring tool

drilling must be done first

Question 10

tapping

Answer 10

tapping tool used to cut surface of hole = internal threads;
tool is rotated instead of workpiece

drilling must be done first
