Cycloidal 2. ; Material Selection: The choice of materials can impact KEYWORDS: Cam, follower, cam profile INTRODUCTION The transformation of one of the simple motions, such as rotation, into any other motions is often conveniently accomplished by means of a cam mechanism A cam mechanism usually consists of two moving elements, the cam and the follower, mounted The cam can be started from scratch, or loaded from an existing file, edited and saved again. Disk cams with translating and oscillating followers Polynomial Cams It is possible to design a cam profile that will give us precisely the features we desire in kinematic behavior at the start and end of a cycle of cam rotation using polynomial cams (there are trade-offs too, however). 1a), assumed given are follower displacement S vs. You can compare up to four cam cards. is dedicated to providing the design engineer with accessible software for developing high speed machine The cam profile bb is a product of the enveloping motion of a series of rollers. For example, a cam may have a rise region for 20 degrees of rotation, followed by a dwell region for 40 degrees, and then a fall region for 300 degrees. The second step is the application program itself with Y_CamIn and Y_CamOut blocks to engage and disengage the cam function respectively. Ex. Cam Angular Velocity -- The rotational velocity of the cam. that will certainly simplify things and while NX may not have an explicit 'Cam Design' tool, if you're willing to live with those limitations, it wouldn't be that difficult to create the profile using the NX sketcher. 10 ‐ Generated Cam Profile for Plate Cam with Roller Follower 4.
