An Analytical Design Method for Milling Cutters With Nonconstant Pitch to Increase Stability, Part 2: Application
نویسنده
چکیده
Chatter stability in milling can be improved significantly using variable pitch cutters. The pitch angles can be optimized for certain chatter frequency and spindle speed ranges using the analytical method presented in the first part of this two-part paper. In this part, the improvement of productivity and surface finish are demonstrated in three example applications. It is shown that chatter stability can be improved significantly even at slow cutting speeds by properly designing the pitch angles. A roughing example demonstrates substantially reduced peak milling forces which allows higher material removal rate. @DOI: 10.1115/1.1536656#

An Analytical Design Method for Milling Cutters With Nonconstant Pitch to Increase Stability, Part I: Theory
Chatter vibrations result in reduced productivity, poor surface finish and decreased cutting tool life. Milling cutters with nonconstant pitch angles can be very effective in improving stability against chatter. In this paper, an analytical stability model and a design method are presented for nonconstant pitch cutters. An explicit relation is obtained between the stability limit and the pitch ...
متن کاملFlank milling with flat end milling cutters
In this paper, we give a detailed mathematical understanding of flank milling with flat end cutters, which we use to develop a method for milling with such a cutter. This method slides the cutter along two rails, providing two points of contact on the surface.
متن کاملMachining Free-Form Surfaces
This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining. The method comprises three steps: (1) the calculation of the tool-path interval...
متن کاملAlgorithms for selecting cutters in multi-part milling problems
This paper describes geometric algorithms for automatically selecting an optimal sequence of cutters for machining a set of 21⁄2D parts. In milling operations, cutter size affects the machining time significantly. Meanwhile, if the batch size is small, it is also important to shorten the time spent on loading tools into the tool magazine and establishing z-length compensation values. Therefore,...
