MECH 200 1st Edition Lecture 11Cutting Tools For Turning1. Characteristica. Tough – Wear Resistantb. Chemically Inert – it will not react with the material that it is cuttingc. Red Hardness- Ability to maintain hardness under extreme temperatures2. Materialsa. Carbon Steelb. HSS –High Speed Steel (Type M or T)c. Cobalt- a percentage of cobalt is added to a composite metal (Typically 5-10%) i. Increases the Red Hardness and Toughness of the materiald. Carbidei. Brazed – Permanently attached as cutting faceii. Inserts – Removable/adjustable bolted on piecese. CBN – Cubic Boron Nitridef. Titanium Nitride Coatings – Increases tool life 10-25%g. Ceramic – Only good if constant contact is held with material being cuth. Diamond - (PCD) 3. Nomenclaturea. Cutting Edge – Does Seperatingb. Rake Angles – Back and side anglesc. Clearance angles – Primary angled. Chip Breaker – Causes a break in continuous chipsi. It is a trough that is found behind the cutting edge that curls chips until they breake. Nose Radius – Dissipates HeatPlanning MachinesThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.1. Horizontal Machine2. Vertical Machine3. Gantry Machine – The cutting tool moves around the cutting area instead of moving the pieceCutters1) General Typesa) Ball end Mill, Plain Mill, Dove Tail Mill, Four Fluted, Corner Rounded, Two Fluted2) Applicationsa) Angle Cutter – Cuts anglesb) Plain/Slab Cutter – Cutting wide swathes of Materialc) Slitting Saw – cuts thin slits (Slit <1/4”) (Used on Horizontal Machines)d) Face Mill – Cuts Large Swaths of
