Working Envelop

The maximum dimensions of a part that is produced using CNC machining, is directly related to the machine’s working envelop. The work envelop of a CNC machine is the total area the CNC machine can cover moving in the X, Y, and Z axes. The work envelop of a machine determines its travel limitations which in turn determines the maximum part size it can produce.

Tolerance

Why are tolerances important?  Because no one machining process can produce exact dimension. Variances can be caused by multiple factors including material, equipment, temperature and the process used to machine the part. Machining tolerance is the amount of acceptable variance in the dimension of a part. At PV, our customers typically require +/-.005" on their drawings unless otherwise specified, however we see +/-.0005" on many of our customer drawings for key dimensions and critical characteristics.

Milling PV’s capabilities include holding milled positional tolerances to +/-.0005" and occasionally +/-.0002" on adjacent features, to +/-.001" on non-adjacent or Datum oriented features.
Turning PV routinely holds turned tolerances to +/-.0003" and occasionally +/-.0002" on a complete spectrum of materials, ranging from aluminum to high temp alloys.
Electrical Discharge Machining (EDM) PV’s Electrical Discharge Machining can maintain a hole size of +/-.0005; locations +/-.0005; and profiles .0020.
