2. Cam (mechanism) - Wikipedia

   en.wikipedia.org/wiki/Cam_(mechanism)

   Constant lead barrel cam in an American Pacemaker lathe. This cam is used to provide a repeatable cross slide setting when threading with a single-point tool. A cylindrical cam, or barrel cam, is a cam in which the follower rides on the surface of a cylinder. In the most common type, the follower rides in a groove cut into the surface of a ...

3. Bridgeport (machine tool brand) - Wikipedia

   en.wikipedia.org/wiki/Bridgeport_(machine_tool...

   Machine tapers for tool holding included Morse tapers (on early models) and the R8 taper (a widely used standard that Bridgeport created) on most models. Both Morse and R8 allowed for both collets and solid holders, and a drill chuck could be held by either of the latter. Currently R8 and Erickson #30 Quick Change tool holders are available.

4. Camshaft - Wikipedia

   en.wikipedia.org/wiki/Camshaft

   A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.

5. Oldsmobile V8 engine - Wikipedia

   en.wikipedia.org/wiki/Oldsmobile_V8_engine

   Performance modifications included a "hot" camshaft (in reality, just a camshaft used in various applications during the '70s with .440"/.440" lift and 196°/208° duration at .050"), stiffer valve springs, a larger vibration damper (same as all '73-'79 350s, 403s, and 455s), a Y-pipe dual-outlet exhaust system, and richer secondary metering ...

6. Chuck (engineering) - Wikipedia

   en.wikipedia.org/wiki/Chuck_(engineering)

   A self-centering chuck, also known as a scroll chuck, [2] uses jaws, interconnected via a scroll gear (scroll plate), to hold onto a tool or workpiece. Because they most often have three jaws, the term three-jaw chuck without other qualification is understood by machinists to mean a self-centering three-jaw chuck.

7. Fixture (tool) - Wikipedia

   en.wikipedia.org/wiki/Fixture_(tool)

   A common type of fixture, used in materials tensile testing (Grip-Engineering). A fixture is a work-holding or support device used in the manufacturing industry. [1] [2] Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchangeability.

8. Machine taper - Wikipedia

   en.wikipedia.org/wiki/Machine_taper

   Tools with an R8 taper are inserted directly into the machine's spindle. R8 collets are typically used to hold tooling with round shanks, although any shape can be held if the collet has the corresponding shape cut in it. The collets have a precision bore with axial compression slots for holding cutting tools and are threaded for the drawbar.

9. Timing belt (camshaft) - Wikipedia

   en.wikipedia.org/wiki/Timing_belt_(camshaft)

   In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or gears), which in turn actuates the intake and exhaust valves. [1] These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. [2]
