Drawing-led guidance for machining, materials, tolerances, quality and production decisions, written for engineers and procurement teams.
Use the categories above to move between machining fundamentals, drawing preparation, material choices and inspection strategy.
Treat +/- 0.005 mm as a feature-level precision band, not a blanket CNC default. The cases when +/- 0.005 mm CNC tolerance is realistic are short, rigid metal features: a finish-bored hole with L/D…

How to reduce CNC machining cost is mostly a machine-time problem: fewer setups, larger tools, and fewer finishing passes. Enlarge internal fillets so a 6 mm or 8 mm end mill can cut the…
Read guide
CNC fillet radius vs end mill size is a one-way constraint: the internal radius on the print cannot be smaller than the mill radius, or the shop must switch to a smaller cutter. Pick…

How to dimension a CNC drawing for quote is a documentation job, not a styling job. The PDF must carry a datum scheme, overall size, hole locations, thread callouts (class and depth), a general…

CNC wall thickness guidelines for milled parts are stiffness rules, not catalog minimums. For 6061-T6 aluminum, 1.5 mm is a practical short-wall target; 0.8 mm is a lower bound that often needs extra finish…

A CNC machining drawing package checklist is the set of files and notes a factory needs before it can quote without guessing. Send a STEP (AP214 or AP242) plus a PDF drawing with ASME…

A CNC machining DFM checklist is the last pass you run on STEP and PDF files before you send a China RFQ. Fix missing datums, default tolerances tighter than ISO 2768-1 (1989) medium class,…

What to include in a China CNC RFQ is the drawing package plus the commercial fields that change the number. Attach STEP and PDF, revision, alloy and temper, finish, quantity breaks, and the inspection…

6061 vs 7075 for CNC parts is a strength versus process choice. 6061-T6 typically publishes around 310 MPa tensile and 276 MPa yield, machines cleanly, anodizes evenly, and resists corrosion better in most atmospheres.…

5-axis vs 3-axis CNC machining is a setup and access decision, not a quality slogan. Use 5-axis (or indexed 3+2) when the part has compound holes, undercuts, or datums that must stay in one…
