just a little about what i do to fill in some blanks.
i work in a machine shop, i’m now the supervisor of the CNC mill department.
i schedule the jobs for the 19 machines in my department, decide what machine and what operator will make the parts required.
for the most part i program all the machines myself and design the processes that we will use to manufacture them.
i am in the process of training a couple guys to help pick up slack with programming but this takes a while to master, not the programming side of it as much as the process side.
how you will go about making the part from start to finish, what tools, what order features need to be done, how to locate and hold the part to do them, all that knowledge comes from trail and error so i still have to stay involved in that part.
i try to let them make mistakes to learn from and try to help them avoid the big ones, that i already paid the dues on.
the software i use to program the machine to make the parts is Edgecam. (
http://www.edgecam.com/) it’s a CAM software (computer aided manufacturing)
it basically makes code for the machine to know what to do and where to do it. once you set up the machine with the proper locations and tools it needs the machine takes over and machines the part in the order and with the tools you told it to in the code.
75% of the parts we make are made of stainless steel the rest is comprised of any other material, we cut anything. from really hard and tough, high nickel content material to aluminum or plastics. every material is machinable once you figure out what tools you need and how to use them.
i started at at this shop in 1992 and was brought in to be the lead set up guy for the person that did my current job at the time. (he is still my boss we just both shifted up a notch.)
we manufacture many different parts for many different industries including:
medical parts - mostly tools used during operations
aerospace part - variety of prototype parts for research and development.
automotive parts - prototype brackets and valves, some short run production
printing press parts - parts for high speed printing presses made by kodak.
being as diversified as we are helps us to maintain a steady workload, some industry is always up when another is down, so we tend to ride the wave.
the only problem becomes when more then one is up at the same time, then we end up overloaded like we have been all this year.
this year we have added 6 new machines in my department and 4 more in the other departments. we have also hired 8-10 people so far, we are close to 1/3 growth in capacity before the year is over in my deparment.
we already had 2 Haas trunion machines that we purchased in 2005, so i was familiar with the concept of 5 axis machining.
this is basically holding a piece of material and twisting and spinning it around to different angles so my cutting tools can access every side of the part i’m making except the side i’m holding on to.
this makes almost every part a 2 step process, 1 in the trunnion doing 5 sides of the part and the second finishing the side we held onto for the first operation, thus eliminating multiple set ups that the parts used to require when you could only access one side at a time.
the challenge of deciding how to go about this whole process, what tools to use, how to hold it, what order to do each feature so it does’t affect another. etc. and figuring out how to do it right the first time out of the gate is the fun part of my job.
being the guy that has to be the babysitter and tell grown men that are being paid to earn their money by staying busy, and dealing with all the problems immature people create is the suckass part of my job that i hate.
as busy as we have been I’ve got unlimited amount of hours available for the taking and have worked 7 days a week at around 65 hours a week for this whole year so far. i took off maybe 6 days total and 3 were for WEC/Arnold’s in Columbus last March. I’m not sure whether it’s a sense of responsibility or just plain greed that makes it so hard to say no when the hours are there. i do go in early and try not to stay late very often so i get time for the young ones. only half day on weekends while the kids sleep thru morning then off to plans with them.
thats the nutshell version i guess, hit me up if you got questions
