STEP, DXF, PDF: Which File Format Should You Send to a CNC Supplier?
The speed and accuracy of a CNC contract-manufacturing quote depend on the file package you send: if you send only a PDF, the supplier remodels the part; if you send only a STEP file, tolerances and material remain unclear. This guide explains the role of STEP, IGES, Parasolid, DXF, PDF and native CAD formats in CNC manufacturing, defines the ideal file package and lists common mistakes such as revision, unit and file-name errors.

DFM: Cutting CNC Costs by 30% with Design for Manufacturability
Most of the cost of a CNC part is decided at the design desk: an unnecessarily tight tolerance, an internal corner radius that does not match a standard tool or an extra set-up increases the unit price by tens of percent. Design for manufacturability (DFM) eliminates these cost items without changing the function. This article explains 15 practical DFM rules for CNC turned and milled parts, the cost impact of each and how to hold a DFM discussion with your contract manufacturer.

How to Choose the Right CNC Contract Manufacturer: A 15-Question Checklist
The supplier with the lowest quote often turns out to be the most expensive one: late deliveries, out-of-tolerance parts, unclear communication and remanufacturing costs quickly wipe out the price difference. This article sets out the 15 questions you should ask when evaluating a CNC contract manufacturer in Turkey or any other country, the risk behind each question and what a good answer looks like.

CNC Lathe or Swiss-Type Lathe? The Right Choice for Your Part
When requesting a quote for a cylindrical part, whether the supplier will produce it on a conventional CNC lathe or a Swiss-type lathe determines the unit price and lead time. The Swiss-type lathe is unmatched for small-diameter, long, and high-volume parts; the CNC lathe, on the other hand, excels at large diameters, low volumes, and jobs requiring complex clamping. This article compares the two technologies using a decision matrix.
