Explain what is Undercutting of cams?
Answers
undercutting occurs whenever the radius of the curvature of the cam profile is less than the radius roller. the only way to eliminate this condition is by having a larger base.
Answer:
Cam undercutting is a common occurrence during camshaft production. To transform rotational motion into reciprocating or oscillating motion. machines utilise devices called cams, which rotate.
Explanation:
Because of their peculiar form, they may direct a follower to do a specific action. The valves of an internal combustion engine are opened and closed with the help of a revolving shaft called the camshaft.
Cams are machined from a cylindrical shaft during the production of camshafts. Shaft material is removed to form the cam profile. During the machining process, if the cutting tool removes too much material from the shaft, it will undercut the cam profile, producing a groove or undercut. The follower may get jammed in the track or undercut, damaging the camshaft and leading to engine trouble.
The undercutting of cams may occur for several causes. Too big of a cutting tool for the cam profile is a typical culprit. Undercuts may be caused if the device digs too deeply into the material. A ragged profile may also result from using a dull cutting tool, which causes the material to rip instead of being cut smoothly.
Cam undercutting may be avoided with strict process control throughout production. The particular cam profile must choose the cutting tool to guarantee appropriate cutting, and cutting conditions must be closely monitored. The cutting tool should be sharpened or changed often to make exact cuts.
In conclusion, the undercutting of cams is a phenomenon that may occur during camshaft production. It appears when excessive amounts of material are removed from the shaft during machining, leading to depressions or divots in the cam profile. Undercutting may be avoided with adequate process control during manufacture and a well-maintained cutting tool.
