By the aid of the turning operation you can obtain:
Cylindrical surfaces

Conical surfaces

Profile surfaces
The chuck is used for clamping the tool....

[TRUE or FALSE]?
FALSE
The collet is used for:
Clamping workpieces

Clamping tools
Drilling is producing a hole with a better surface roughness than reaming.

[TRUE or FALSE]?
FALSE
When you are doing turning without coolant we can obtain:
A burned surface
You purchase a turret lathe instead of a conventional lathe for:
Higher productivity
A 6-in. long, 0.5-in. diameter 304 stainless steel is being reduced in diameter to 0.480 in. by turning on a lathe. The spindle rotates at N=400 rpm, and the tool is travelling at an axial speed of 8 in./min. Please calculate the cutting speed, material removal rate, cutting time. Results:
v=fN f=v/N
MMR=pi(Davg)(d)(f)(N)
t=l/fN
Please identify the process from the figure:
Peripheral Milling
Please identify the drill from the figure:
Spade drill
Please identify the milling process from the figure:
Conventional Milling
Please identify the marked drill from the figure:
Center drill
You have to mill a titanium alloy. For this you are using a cutter with a diameter of 3 in. and 10 teeth. From the Tables you have:
• Speed for Titanium alloy = 200 ft/min
• Feed = .006 in./tooth
Please determine N (rpm) and v [linear speed of the workpiece] in (in./min)
Results:
N=255 rpm

v=15.3 in./min
Assume that you have to perform a face milling operation (see figure) & assume that D=150 mm, w=60 mm, l=500 mm, d=3 mm, v=0.6 mm and N=100 rpm. The cutter has 10 inserts and the workpiece material is a high-strength aluminum alloy. Calculate the material removal rate, cutting time, and the feed per-tooth, & estimate the power required.
MMR=108000 mm^3/min [MMR=w dv]
t=1.083 min [t=l +lc/v]
f=0.6 mm/tooth [f=v/Nn]
P=1.98 kW
The gears can be manufactured using the following processes:
Milling
Broaches are used in order to obtain:
Profiled surfaces
