introduction：inUGIn the software，There are several generation tools for generating curves，Generative line、arc、ellipse、sample article、parabola、Hyperbola and so on，It is particularly worth mentioning，inUGIn the software，Has to generate equations Expression of the function of the curve，And the curve is also correlated，That is, if the equation changes，Curve bar Will change with，This is especially suitable for some specific needs，Such as CAM modeling。 inUGThe modeling steps of the software curve are mainly composed of two steps：The first step is to create the expression，The first The second step is to build the curve of the equation，Here is an example，Explain it

introduction：Commonly saidfagImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]The noise is caused by the vibration of the bearing directly or indirectly with the surrounding structure。That is to say, the problem of a lot of noise is the vibration problem of the bearing during the entire application process。Because the number of rolling elements carrying loads varies during operation，Causes the load direction to shift，So vibrations are created。Simultaneous components of waviness in the bearing ring and bearing
