Micromachining, Micro Drill, Milling, & Machines [ .

Since micro-mills are particularly susceptible to deflection, a conventional milling approach is preferred since deflection will be along the tool path and not into the workpiece. Deflection into the workpiece leads to increased chip load and inaccuracy as well as encouraging chatter if the workpiece is very thin.

Let the Tool Path Help the Tool | Modern Machine Shop

Rather than repeating the same arcing tool path ever farther into the part, trochoidal turning involves changing the cutting direction at the end of every pass. That is, the round insert traces the shape of the feature toward the left, then goes deeper to trace the shape of the feature toward the right, and so on until the feature is finished—as shown in Figure 5.

Efficient Tool-Path Planning for Machining Free-Form .

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.
