I need some advices on making gage for true position of boss; let say I have a boss diameter 1.00+/.030 and true position is .020(RFS)/A/B/C . I like to make a plug gage with a hole, the plug gage is located on the tooling point fixture; what size of the hole should be so where the boss go into...
thank for your reply, John. Any advice on picking a highest point of datum target area of .250 dia on cmm.?
cmm does save time when the production parts need to be inspected some critical dim; you just make 1 program and repeat for let say 100 parts.
In many years working as cmm programmer, I alway use spherical ball probe to pickup datum targets A1,A2,A3 to establish datum -A- plane.
when the customer ask the question, I was surprised.You are right about setting up on fixture is the right way to inspect the dimensions because it complies...
if I have a primary datum -A- with 3 datum targets A1,A2,A3 with .250 diameter area shown on Blueprint, how do I set up datum -A- plane on the Coordinate measuring machine? I need your help. thank for the last email.
I have a customer ask us how do we established datum target area of .250 dia, I take 1 point in this area s.b enough to define datum target area. The customer did not like my answer? so I need your advice on how to simulate datum target on the cmm machine.Thank
