Abstract |
The paper presents a mathematical model of the helical surface
roughness Rz, obtained by the form-generating method with a
to-size tool with a standard profile of cutting tool inserts. This
machining method has maximum productivity with large pitches
of the helix. The surface roughness of the auger flight is an
important parameter since it works in a friction pair with an
elastic element. The resulting dependence makes it possible to
predict surface roughness in any of its sections, considering the
helix curvature, depending on the feed and the cutting tool tip
radius. The obtained dependence allows comparing the
numerical solution with the linearized one obtained by finding
the minimum distance from the intersection points of the tool
edge circles at helical surface adjacent cutting points to the
straight line connecting these adjacent points. |
