State three reasons that machining is commercially and technologically important.
Give this one a try later!
• Is applicable to most materials
• Can create a wide variety of shapes
Close tolerances and good surface finishes
, Counterbore is for what type of fastener? Countersink?
Give this one a try later!
• Counterbore: socket head cap screw (sits flush with or below the surface)
Countersink: bolt, screw, or rivet
Why are surface and cylindrical grinding processes technologically and commercially
important?
Give this one a try later!
Fine surface finish and very close tolerance
How is feed rate denoted for a manual lathe and drill press?
Give this one a try later!
• Manual Lathe = feed/rev
Drill press = inches/rev
Given the following parameters, find the appropriate RPM and feed rate in
inches/minute.
Cutting Speed: 150 SFM
Tool Diameter: 0.875" End Mill
Chip per Tooth: 0.002"
Number of Flutes: 4
