Hi For position tolerance coordinates should be maintained within the tolerance zone from the tolerance of feature control frame, based on number of datum, I've shared this for tolerance split up!!
Sir pcd holes la true position cmm use pannama epdi check pandrathunu sollunga.. 8 holes (22.5 degree) Basic dimensions PCD and ANGLE Datum (A) is ID Position tolerance 0.2/B
First find the each holes X, Y co-ordinate calculate panunga (use triginometry (or) CAD) Then use two PIN to insert on the two straight holes & straight the two PINs verically with the help of tri-square Now fix the part with any clamping Now you can use height gauge (trimos (or) micro height 2D)to measure the hols Y distance from datum(center hole) Rotate the part 90degree then repeat the same, this measurements consider as X distance Now use the video stated formula to calculate the true position.
We already explained more about surface roughness in our channel. pls check in our channel playlist. thanks ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NbAPRyoMYZQ.html
