CNC Lathe vs. Mill: Choosing by Part Geometry
Compare CNC lathes and mills by the features they cut, the setups they need, and the relationships that matter on a finished part.

Understand how spindle layout, axis motion, tooling, workspace and automation combine to determine what a CNC machining center can do for a part.

See how cutting force, unsupported length and support placement affect slender shafts, then use a diameter map to separate deflection, chatter and inspection issues.

Read VMC specifications as job-specific limits. Worked travel and clearance examples explain why table size, axis stroke and part dimensions are different.

See how OD turning, facing, grooving and parting off differ in tool contact, feed direction and finished features, with a drawing checklist and shaft example.

Decode high-axis CNC descriptions using named machine examples, axis groups and robot layouts, and distinguish a machine total from coordinated cutting motion.
