5-Axis Machining

Five-axis machining lets the cutting tool approach a part from almost any direction, so complex contours, angled faces, and deep cavities can be produced in fewer setups. For parts with tight tolerances across multiple faces, fewer setups mean fewer datum shifts and less accumulated error. Five-axis work is carried out on simultaneous five-axis and 3+2 machines within our partner network, producing complex non-standard components for robotics and emerging industries.

When Five-Axis Makes Sense

Five-axis work pays off when a part has sculpted surfaces, ports or holes at compound angles, undercut features, or tolerances that must hold across several faces. It is also effective for parts that would otherwise need three or four separate fixtures, because each additional setup adds handling time and stack-up error. For simple prismatic parts, three-axis machining is usually faster and more economical — we will recommend the simpler route when it meets the drawing.

Typical Parts

Work includes multi-face housings, angled connector bodies, structural frames with machined interfaces, impeller-type geometry, and complex brackets where weight-reduction pockets and mounting datums have to coexist. These parts commonly appear in robot joints, automated handling equipment, and compact motion assemblies.

Process Control

Complex parts are programmed and simulated before cutting to check tool reach, holder clearance, and collision risk. Critical features are probed or inspected in process, and the final inspection report records the dimensions agreed during drawing review. Where a feature cannot be measured after machining, we agree on the inspection method before production starts rather than discovering the gap at delivery.

What to Send

A 3D model is the most useful starting point for five-axis work, together with the drawing that defines datums, critical dimensions, and acceptance criteria. If only a drawing exists, we will review whether the geometry can be machined as specified and tell you where the design may need a small change to avoid unnecessary cost. For parts that will be inspected on a CMM, we agree on datum definition and fixturing before the first cut, because a feature that cannot be held repeatably cannot be measured repeatably.
