"Our company has all 5-axis machines so that we can support a variety of different industries that we're in. The reason we got into 5-axis machining is because it cuts the machining operations down; first operation can pick up five of the six sides of a part, and the final operation can pick up the final side that's bolted down to the table.

Tolerances can be affected by several factors such as the type of machine, the type of cutting too l, the material being machined, and the complexity of the part. Typical machining tolerances for common manufacturing processes are: Turning: ±0.005″ to ±0.015″ Milling: ±0.005″ to ±0.015″ Drilling: ±0.005″ to ±0.015″

Standard tolerances are the most widely used machining tolerances for most fabricated parts today. These tolerances typically fall within the range of ±0.005" and ±0.030", and machinists usually apply them when customers do not specify tolerance levels. For instance, Table 1 shows the standard tolerances for different manufacturing …

Tolerances are measured as part of post-CNC machining quality inspection. Required tolerances also help to determine the manufacturing methods necessary to machine a certain part. Tighter tolerances may require more sophisticated manufacturing equipment or additional post-processing to get the dimensions within the specified ranges.
