Summary of the Article: Cam Profile
The cam profile is the actual working surface contour of the cam. It is the surface in contact with the knife-edge, roller surface, or flat-faced follower. The base circle is the smallest circle drawn to the cam profile from the radial cam center.
The engine cam profile refers to the shape of the individual lobes on the camshaft. The camshaft pattern refers to how the profile of the intake and exhaust lobes compare to each other.
In cam and follower systems, the cam is a profiled disc, cylinder, or sphere that rotates. The shape or profile of the cam influences the motion of the follower, which is a rod in contact with the cam. The contact between the cam and follower is achieved using a spring or the follower’s weight.
In engineering drawing, the profile of the cam imparts a follower to move in a particular way. There are two main categories of cams: plate/face cams and cylindrical cams.
CAM stands for Computer Aided Manufacturing. It is the use of software and computer-controlled machinery to automate a manufacturing process.
There are different types of cam profiles, including disc or plate cams, cylindrical cams, translating cams, radial cams, and wedge cams.
The point of camming an engine is to modify the camshaft to build a custom engine that performs better within a particular RPM range.
Advancing the cam moves both the intake and exhaust centerlines an equal amount, resulting in earlier valve timing events. Engines typically respond better with a few degrees of advance, probably due to the importance of the intake closing point on performance.

What is cam profile in cam and follower
The cam is a profiled disc, cylinder or sphere that rotates. The shape or profile of the cam influences the motion of the follower. The follower is a rod that is in contact with the cam. The contact between the cam and follower is achieved using spring or the follower's weight.
What is cam profile in engineering drawing
The profile of the cam imparts (causes) a follower to move in a particular way. This can be seen if we examine the diagram below. As the shaft is rotated the cam rotates with it causing the follower to move up and down. Cams fall into two main categories: plate/face cams, and cylindrical cams.
What cam stands for
What is CAM Computer Aided Manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process.
What are the different types of cam profile
The following five types of CAM:Disc or Plate Cam.Cylindrical Cam.Translating Cam.Radial Cam.Wedge Cam.
What is the point of camming an engine
The term “camming” refers to the modification of a truck's camshaft. While it may sound justifiably complex, the process of changing out the camshaft allows you to build a custom engine that performs better within a particular RPM range.
What does a cam do for performance
Advancing the cam moves both the intake and exhaust centerlines an equal amount, resulting in earlier valve timing events. Engines typically respond better with a few degrees of advance, probably due to the importance of the intake closing point on performance.
What is the advantage of cam profile
By proper designing of cam profile, a variety of follower motions can be obtained. Able to operate accurately. Easy mechanism to convert the rotational motion to reciprocating or oscillating motion. The number of components reduces with the use of a cam and follower mechanism.
What are the 4 types of cam
CamsCircular. Circular cams use an off-centre pivot to cause the follower to move up and down.Pear. Pear cams are called this as they have the shape of a pear.Snail or drop. Snail or drop cams have the appearance of a snail shell.Heart-shaped or constant velocity.
How do you draw a cam profile diagram
Question. Let's make a cam profile with the help of this displacement diagram so to make a cam profile make a center lines give the center as o and make a base circle which represents the minimum
What are examples of cam in engineering
Perhaps the most common example of a cam is an internal combustion engine. Car motors operate through a system of cams mounted on a cam shaft that open and close valves to regulate inputs (air and fuel) and outputs (exhaust) within the piston-cylinder assembly.
How does CAM work
The CAM system works by substituting hand-made jigs with software that defines the actions and processes of a machine directly. Computer-aided manufacturing software translates drawings and data into detailed instructions that drive automated tools/machines.
What are the benefits of CAM
The benefits of CAM
Greater accuracy and consistency, with each component or finished product exactly the same. Greater efficiency as computer controlled machines do not need to take breaks. High sophistication in terms of following complex patterns like tracks on circuit boards.

Does camming increase HP
Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine's performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.
Does camming a car make it louder
Yes, it will be louder.
Does cam increase horsepower
Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine's performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.
How does changing a cam add horsepower
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You'll idle slightly rougher with a performance cam, but get a throaty rumble that's desirable for some gearheads, depending on your vehicle.
Does a bigger cam affect timing
See all 16 photos16 photos If your street engine doesn't have a vacuum advance canister, you are limiting your engine's part-throttle performance. The bigger the camshaft, the more it really needs part-throttle timing at low engine speeds.
What makes a cam high performance
Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam's power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
How many types of cam profiles are there
Two major types of camshafts exist flat tappet and roller.
Which type of circle is used to draw a cam profile
Base Circle: It is the smallest circle, keeping the centre at the cam centre, drawn tangential to cam profile. The base circle decides the overall size of the cam and thus is a fundamental feature.
Which point we can trace the cam profile
Tracepoint – It is the reference point on the follower to trace the cam profile such as the knife of the knife-edge follower and centre of the roller of roller follower. Pitch curve – Curve is drawn by the tracepoint assuming that cam is fixed, and the tracepoint of the follower rotates around the cam.
