Angle milling with a small end mill on a tilted workpiece in a CNC vise
Angle Milling: A Comprehensive Guide to Techniques, Tools, and Applications

Angle milling is a specialized milling method in which the tool cuts at a non-orthogonal angle to the workpiece surface, enabling precise inclined planes, dovetail guides, draft angles and other functional geometries. The article explains why designers use angle milling, how it is executed through workpiece tilting, spindle tilting or form cutters, and what types of angle cutters are available. It also reviews suitable materials, typical applications in machine tools, molds and aerospace parts, and the main advantages and limitations compared with conventional milling.

Undercut Machining: Types, Industrial Applications, and Common Challenges

Undercuts are highly challenging geometric features in precision machining, characterized by recessed areas that are "hidden" from the direct path of standard cutting tools. This article explores common undercut types—from T-slots to dovetails—and analyzes the core technical hurdles regarding tool rigidity, chip evacuation, and inspection. By implementing Design for Manufacturing (DFM) strategies, such as aligning with standard tool sizes and controlling depth-to-width ratios, engineers can maintain part functionality while significantly reducing the costs associated with these complex details.

Boring Machining Process
Boring Machining Comprehensive Overview

Boring is a high-precision, single-point cutting finishing process. Its primary value is performing geometric correction and size refinement on existing holes to achieve tolerances of IT6 or better. Unlike drilling, boring utilizes a single-point adjustable boring bar and the machine's high-rigidity system to reliably eliminate geometric errors like positional and straightness deviations left behind by preliminary operations. Boring types include through-hole (for uniform diameter), line boring (for co-axiality), and face boring (for perpendicularity). The process is executed on highly rigid platforms, such as CNC Machining Centers, Horizontal/Vertical Boring Mills, and dedicated Fine Boring Machines.
