[QUOTE="SidecarFlip, post: 609396, member: 39764"] Interesting subject. Every (considered straight bore or line) is curved if the tolerance of measurement is fine (close enough). Gaging in thousands is like a potholed road compared to millionths..... or.... 0.001 versus 0.000001.... and it has everything to do accuracy of the machine tool, tooling, ambient temperature at which the machining took place, remperature at the cutting edge, operator skill and a multitude of other varibles. In reality, nothing is straight, everything has curvature to some degree when the unit of toerance become acute. So, the term straight without curvature applies to the degree of acceptable accuracy in the machining process, the cost of the process and the degree of acceptance by the end user in relationship to the cost......
