True Position Tolerance Explained for CNC Machined Parts

True Position Tolerance Explained for CNC Machined Parts

by admin | Sep 14, 2026 | CNC Machining

True position is one of the most commonly used geometric tolerances on engineering drawings, particularly for holes, bores, pins and other features that must align correctly within an assembly. At first glance, it can appear more complicated than a conventional...
Datums on Engineering Drawings: How They Control CNC Machining and Inspection

Datums on Engineering Drawings: How They Control CNC Machining and Inspection

by admin | Sep 7, 2026 | CNC Machining

Datums are fundamental to many engineering drawings because they establish the reference framework used to locate, orient and inspect important component features. They help ensure that designers, machinists and inspectors are all working from the same set of...
Flatness vs Parallelism in CNC Machining: What’s the Difference?

Flatness vs Parallelism in CNC Machining: What’s the Difference?

by admin | Sep 1, 2026 | CNC Machining

Flatness and parallelism are two common geometric tolerances used on engineering drawings, and although they can look similar at first glance, they control different characteristics of a machined component. Flatness controls the form of an individual surface, while...

CNC Machining Hole Tolerance: Drilling, Reaming and Boring Explained

by admin | Aug 31, 2026 | CNC Machining

Holes are among the most common features found on CNC-machined components.They can also be among the most functionally important. A hole may simply provide clearance for a fastener, or it may locate a dowel, carry a bearing, guide a shaft, provide a sealing surface or...
What Does ‘Break All Sharp Edges’ Mean on a CNC Machining Drawing?

What Does ‘Break All Sharp Edges’ Mean on a CNC Machining Drawing?

by admin | Aug 25, 2026 | CNC Machining

“Break all sharp edges” is one of those engineering drawing instructions that appears simple until someone has to decide exactly what it means. For a CNC machining supplier, the intention is usually clear: finished components should not be supplied with unwanted burrs...
