A surface along which all the points lie along single plane is called as perfectly flat surface. 0.01 9 Tolerance 0.01 Lowermost plane Uppermost plane The maximum material condition is not applicable to Flatness Tolerance zone bound by ...
WebHand drawings are ok. For each of the feature control types (e.g. flatness, angularity, etc.) make a drawing of a simple part that includes a feature for which the control would be appropriate. Complete the drawing by labeling appropriate datums and the appropriate feature with a feature control frame. Clearly label and describe the tolerance zone. WebExpert Answer.
