Machining and finishing guides
Each article separates general engineering principles from project-specific recommendations. Final parameters and capability always depend on the drawing, material, tooling and equipment.
What Is CNC Machining?
How digital instructions, machine motion, cutting tools and inspection turn stock material into a controlled component.
Read the guide →Process selection · 6 minCNC Milling vs Turning
Use geometry—not labels—to decide between rotating tools, rotating workpieces or a combined process.
Compare processes →Process engineering · 8 minSpeeds and Feeds, Explained
Understand cutting speed, spindle speed, feed per tooth and why a handbook value is only a starting point.
Understand the variables →Surface finishing · 7 minAluminum Anodizing Guide
What anodizing changes, why pretreatment and sealing matter, and what your drawing should communicate.
Plan the finish →DFM · 9 minCNC Design Guide
Internal radii, deep pockets, thin walls, tolerances, datums and a practical drawing package.
Improve your design →Material selection · 5 minMaterials & Finishes
Questions to resolve when choosing aluminum, steel, stainless steel, copper alloys or engineering plastics.
