1. The "Work Envelope" of a machining center...

...describes the machine's travel dimensions. Xometry's partner network includes CNC machiningcenters with 64" (X)" by 32" (Y) by 38" (Z) travel limitations. Keep in mind that the travel limitations do not necessarily translate to maximum part dimensions. Deep features requiring long tooling can cut into the effective work envelope of a machine.

For parts manufactured on a lathe, the critical limiting dimensions are...

...the maximum part diameter and the overall length of the part. Xometry supports parts up to 18" in diameter, but special considerations can be made for larger parts. The maximum overall length of parts that can be supported also depends on the part's maximum diameter. Live tooling lathes can manufacture more complex turned parts with off-axis features, but this often means smaller effective work envelopes.

3. Part size can affect the availability of different post-processing operations

For example, larger parts often do not fit in media-blasting cabinets. Additionally, for large parts that need to be anodized or electroplated, there can be custom racking requirements.
