Typical Tolerances of Manufacturing Processes

tolerances on the lower precision end of the range, but a cheaper alternative likely exists, which could significantly reduce part cost. Figure 15.6 presents another collection of the most common manufacturing processes and common tolerances associated with them as a function of typical part size. The important point to take away fr om this figure is the general trend showing typical ...

What Every Designer Needs to Know About CNC Part

Tolerance is the acceptable range for a dimension which is determined by the designer based on the form, fit and function of a part. Unless specifically called out by the designer, the standard tolerance used by Xometry for CNC machining is +/- .005” for metal parts and +/- .010” for plastic parts.

Grinding - Leaving Certificate Engineering Notes

Tolerances required preclude machining. Grinding can produce flatness tolerances of less than ±0.0025 mm (±0.0001 in) on a 127 x 127 mm (5 x 5 in) steel surface if the surface is adequately supported. Machining removes excessive material.

Precision Metal Grinding - Metal Cutting Corporation

19/02/2019  Depending on how a part will be used, it might not be necessary to hold the very tightest tolerance possible on any given grinding machine — in effect, over-engineering the part and driving up its cost unnecessarily. Instead, while it may be tempting to always go for the tightest tolerance, be realistic about the tolerances you specify for metal grinding and other processes.
