How does a camshaft turn?
The camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position.
How are the cams and the camshafts formed?
The cams and the camshaft are usually formed as a unit, with the cams set at angles so as to open and close the valves in a prescribed sequence as the cams rotate. A separate camshaft for each row of cylinders is driven by gears or chains from the crankshaft. The camshaft, which opens and closes the valves,…
How is pinch turning performed on a camshaft?
Unless a camshaft has an odd number of grooves, the lathe performs turning and grooving operations using both turrets simultaneously when the bar is held between spindles. Because the upper turret is optimized to run close to the main spindle and the lower one is set up to run close to the subspindle, the company does not perform pinch turning.
How are the cams and camshafts in a Volkswagon engine?

How does Comp Cam enable billet racing camshafts?
…enables Comp Cams to produce billet racing camshafts much quicker than when it outsourced camshaft machining. Machining simulation is performed after a program is created for a new camshaft design. After that, a dry run is performed on the lathe followed by a test part created from low-cost mild steel.
How does advancing or retarding a camshaft work?
Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline. This changes the Timing of the valve opening and closing events, in relation to the position of the piston in the cylinder. How is it measured? Find the lobe centerline in relation to the piston’s position in the cylinder.
When does a cam line up with the crankshaft?
When a cam is installed “straight-up,” the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
