SLW210 Posted January 31, 2018 Share Posted January 31, 2018 I think you need to invest in taking a few courses at the local University or Tech School. Quote Link to comment Share on other sites More sharing options...
basty Posted February 1, 2018 Author Share Posted February 1, 2018 That is a tolerance dimension. It tells the machinist that the hole diameter can be a minimum of 0.623 to a maximum of 0.625. And what is the 2X mean? (see below) Quote Link to comment Share on other sites More sharing options...
Cad64 Posted February 1, 2018 Share Posted February 1, 2018 And what is the 2X mean? (see below) It means that a hole of that size and tolerance exists in 2 places on the part. I'll let you figure out where the other hole is located. Quote Link to comment Share on other sites More sharing options...

I'll let you figure out where the other hole is located. I don't know. Can you please tell me where the other hole is located? Since it's not has a dimension, could this hole is the other hole you mentioned? (see below) Edited February 1, 2018 by basty Quote Link to comment Share on other sites More sharing options...
Cad64 Posted February 1, 2018 Share Posted February 1, 2018 Sorry but I would be doing you a great disservice by handing you all the answers. Just look at the drawing. It's very obvious where the other .625 hole is located. If you really can't figure it out, based on the information provided on the drawing, Look below for a hint. 1. There are 3 holes in the part 2. One hole is labeled .625 3. One hole is labeled .50 So where is the other .625 hole? Quote Link to comment Share on other sites More sharing options...

ReMark Posted February 1, 2018 Share Posted February 1, 2018 Where is the other hole located? Let me think on that for a moment................................. I think I know! Quote Link to comment Share on other sites More sharing options...
BIGAL Posted February 1, 2018 Share Posted February 1, 2018 Give a man a fish he eats for one day, teach how to fish he does not starve, something about that word "teach". They do that at schools dont they ? Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 1, 2018 Share Posted February 1, 2018 Perhaps the OP is going the self-taught route which is all fine and well but the onus is on him to do the research to become familiar with the topic at hand before blindly forging ahead.

basty Posted February 1, 2018 Author Share Posted February 1, 2018 What is meant by this? (see below) Which hole is ∅.75? Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 1, 2018 Share Posted February 1, 2018 (edited) It means the diameter of the hole is 0.75 but the hole only penetrates to a depth of .50 understand? When are you going to buy that machinist's handbook? With the power of the Internet it is not that difficult to gain a basic understand of almost any subject matter. Please take a moment to educate yourself regarding dimensioning and tolerancing symbols by clicking on the link below. If you don't know what to search for then ask and someone here will probably be able to provide you with a starting point. http://www.draftingzone.com/shoppingzone/6-1.pdf Edited February 1, 2018 by ReMark Quote Link to comment Share on other sites More sharing options...
basty Posted February 1, 2018 Author Share Posted February 1, 2018 It means the diameter of the hole is 0.75 but the hole only penetrates to a depth of .50 understand? Yes I understand. But which hole is ∅.75? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted February 1, 2018 Share Posted February 1, 2018 Yes I understand. But which hole is ∅.75? Perhaps you should stop looking at that image and take a look at the other one below. I think it may be a bit easier to understand. Quote Link to comment Share on other sites More sharing options...
basty Posted February 1, 2018 Author Share Posted February 1, 2018 Perhaps you should stop looking at that image and take a look at the other one. I think it may be a bit easier to understand. I still don't know, so please someone tell me which hole is D.75? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted February 1, 2018 Share Posted February 1, 2018 I still don't know, so please someone tell me which hole is D.75? I'm assuming you didn't even look at the image I posted because it tells you exactly which hole is D.75. Or maybe you just don't understand basic drafting? You obviously need training, so you should take SLW210's advice about enrolling in a course at a local school. CadTutor is here to help you when you have software problems or when you get stuck and need help or guidance to figure something out, but we're not here to teach you how to be a drafter. I also agree with ReMark about the Machinery's Handbook. It is a "Must Have" for anyone working in the machining/manufacturing industry.

ReMark Posted February 1, 2018 Share Posted February 1, 2018 (edited) I believe it would be the hole at the top. See Cad64's image below. Edited February 1, 2018 by ReMark Applied correction. Quote Link to comment Share on other sites More sharing options...
basty Posted February 1, 2018 Author Share Posted February 1, 2018 I believe it would be the hole at the top. I think the description "1/2 drill" probably might have been someone's attempt to indicate the depth of the hole which really is negated by the 3/4 C-BORE - 1/2 DP notation. Sorry, I don't know what you're talking about? I do not understand. Please explain. Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 1, 2018 Share Posted February 1, 2018 Translation: It's the hole at the TOP. See Cad64's image below. Quote Link to comment Share on other sites More sharing options...
Cad64 Posted February 1, 2018 Share Posted February 1, 2018 Sorry, I don't know what you're talking about? I do not understand. Please explain. Here's a quick section view. Now do you understand? Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 1, 2018 Share Posted February 1, 2018 I stand corrected. Thank you. Quote Link to comment Share on other sites More sharing options...
