geometric dimensioning m l p st f a1 – mmc – maximum material condition: that condition where a feature of size contains the maximum amount of material within the stated limits. Display Options ( * Some values out of range) One input pin to the micro controller is a jumper which determines if the unit powers up in the " micro mode" ( jumper open) or. 6 TOLERANCE HANDBOOK TOLERANCE HANDBOOK 7 Camber Length Width Length Width Camber x 2 COATED AND UNCOATED FLAT PRODUCTS Measurement of Edge Camber ( AS/ NZS 1365: 1996) Camber is the lateral departure of the edge of sheet or strip from a straight line forming a chord. When sheet or strip is laid on a flat horizontal surface. Generally minimum hole size is limited to the thickness of the material. To avoid distortion in sheet metal, holes must not be too close to an edge.
sheet metal tolerance table for hole
For sheet metal 1/ 32 inch or less in thickness, all holes should be at least 1/ 16 inch from the nearest edge. By: Roy Vaillancourt. tolerance applies to single hole machined parts and multi hole machined parts.
