High-speed machining (HSM) combines high spindle speeds, aggressive feed rates, and constant-engagement toolpaths to cut cycle times by up to 10x while improving surface finish and accuracy. This guide covers HSM cutting speeds, trochoidal and adaptive toolpath strategies, material parameters, system requirements, and how SOMI Custom Parts applies high-speed CNC machining to precision parts.

Micro CNC machining produces features below 1 mm with tolerances of ±1–5 µm and Ra 0.2–0.4 µm surface finishes. This guide covers processes, materials, challenges, and how SOMI Custom Parts supports precision micro manufacturing.

Rapid prototyping with CNC machining turns a CAD file into a functional, production-grade part in days. This 2026 guide covers the CAD-to-part workflow, CNC vs 3D printing trade-offs, tolerances, costs, and how SOMI Custom Parts accelerates your prototyping.

A complete guide to CNC machining brass and copper alloys, covering grades such as C360 and C110, machinability ratings, cutting parameters, tolerances, design rules, surface finishing, and applications across electrical, fluid, thermal, and medical industries.

CNC machining vs injection molding: a data-driven guide to choosing the right manufacturing process for your project. Compare cost, tolerances, lead times, materials, and break-even volumes, then learn when to use CNC machining, when to switch to injection molding, and how SOMI Custom Parts can help you decide.

Learn what custom non-standard parts manufacturing is, how it differs from standard parts, and when it is worth the investment. Discover the CNC machining process, key benefits, cost and lead time factors, and how SOMI Custom Parts delivers drawing-controlled precision parts.

Choosing between metal and plastic for CNC machining is one of the most important decisions in custom parts manufacturing. This guide compares strength, heat resistance, weight, corrosion, cost, and machinability of common metals and engineering plastics, and provides a practical three-step framework to select the right material for your application.

Learn how to specify O-ring grooves, keyways, and dowel pin holes on CNC drawings — including ISO 3601 and ANSI B17.1 standards, tolerance tables, machining methods, and specification mistakes to avoid for precision machined parts.

Learn how to design press-fit and slip-fit features for precision CNC machined parts. This guide covers ISO 286 fit tolerances, interference values by material, machining methods, surface finish and coating effects, plus common failure modes so your assemblies mate reliably first time.

Learn how to design threads and tapped holes for CNC machining: engagement depth rules, blind hole clearance, tolerance classes like 6H and 2B, tapping vs thread milling, and inspection with go/no-go gauges.
