machining tolerance for grinding

General ISO Geometrical Tolerances Per. ISO 2768 | GD&T

Variations on dimensions without tolerance values are according to " ISO 2768". All tolerance limits are given in mm. ISO 2768 and derivative geometrical tolerance standards are intendedto simplify drawing specifications for mechanical tolerances. ISO 2768 is mainly for parts that are manufactured by way of machining or removal of materials.

Machining Recommendations for Engineering Plastics (at

Machining (defined according to DIN 8580) is the fastest and most economic way to produce precise components, es-pecially in small volumes. Very narrow tolerances can be achieved using machining procedures. Ensinger itself has decades of experience in the field of ma-chine processing of engineering and high-temperature plastics.

How to hold +/- .0001 bore tolerance - Practical Machinist

a boring bar. I think grinding is out due to the fact that the +/- .0001 goes all the way down into the 15 degree floor. I'm also unsure of how to measure the bore. All I can do for now is order some Deltronic pins in .0001 increments. I could also measure the bore with a CMM once the part is out of the machine. Any advice would be appreciated.
