Hell man, most schools nowadays don't even offer woodshop let alone anything that might be helpful for a carear, HS graduates today have a hard enough time just pulling up there drawers. If it does'nt have Wii or PS on it they don't know what to do with it. The only smart thing most have is there phone. | |

Speaking of schools, When I was in jr high we had wood shop, elec. shop, print shop, plastic shop and we had a metal shop. All of this in jr high. High school we had metal, auto and wood. Quote:

Okay, guys I have a question. If I make a mandrel to mount a gear blank on that has a 1 1/4" bore how much taper do I put on the mandrel per inch (or over 6")? Thanks for the guidance. I guess I need to buy a Machinery Handbook. |

so sadly true... most people expect CNC to be walk up, press start and the machine does EVERYTHING for them... ya right, and the instant gratification mentality is really annoying if it isn't done in 5 minutes, who cares | |

| Re: Machinists Corner Pretty sure its .0005" taper per 1" in length for that size. Diametric not radial. The idea is you want the part to end up in the center of the taper.

Yes that's correct. The average is .006 - .008 tpf

I think one of the measurments is for taper per inch of length and the second is for taper per foot. | |

| Re: Machinists Corner when i was in jr. high we had industrial technologies ( learned to weld , foundry work , and metal work) . in high school we had drafting , wood shop , machine shop . we also had a program to go to a different school to take advanced machining classes ( which i did ) , only bad part for me was they didn't have cnc equipment so i didn't learn to do that . when i got out of school there was jobs for machinists that knew cnc operations but not for regular hands on machinists.

| Re: Machinists Corner I'm a welder at GE Aviation and you are VERY right. Seems many folks don't know the difference between a Machinist and a Machine Operator.

We called them NC (no control or no charge). They would always come to the manual side for tooling for there parts. We had a dcc cmm for inspection. They were always bitchin about how the cmm was not showing true numbers. They wanted to inspect parts with the same program/cnc machine. Boeing had fits lol. I was the CMM programmer and a manual machinist. Good times Evan | |

Not sure if it has been mentioned yet but for all who cant afford CAD Software I use GOOGLE SKETCHUP 8, it's a free download and is very simple for me to use. I run a small machine shop manufacturing D.O.D aircraft parts but have no formal training in CAD-CAM software. Programming G-Code is easy enough with a template for your functions but without blueprints you cant really get started in my opinion.

Hey guys, I have a question. What grade of titanium is best for machinability and durability? The grades start with grade 2 and go up like 5, 7 etc. |
