> I want to thank everyone on here that has helped me at some point or another,because thanks to the help solicited here,I graduated with Machinist I on Thursday. But I would like to relate some fairly serious concerns that have surfaced in recent weeks and months.
I posted early on in my time here about the change in instructors last August. My early impression of the new instructor has changed for the better in some ways,and substantially dimmed in others.
I will give him major props in some of the things that have been improved and created since the change.
He got all of our new equipment up and running,and working on getting the older stuff that is down back running.
Last year at this time,the old instructor had 4 new students starting the May session,giving him 9 total including myself. This coming May,the new guy will have a total of 25,including several new high school kids,a couple guys that were laid off recently and taking on a new trade,and a couple that have a few years in shops doing production-type work on manual machines,and want/need to learn CNC. Also,he will have only the 3rd female I've ever heard of associated with this course. So despite his faults,he IS doing something right.
He has lightened up considerably on his "no loaned tools" policy,out of neccessity,he has nearly as much personal gear as the tool crib does. He's not freaking out over a busted 1/4-20 tap
a youngster broke anymore,because he corrected the fault that allowed a completely green student to use a tap without supervision and initial guidance.
Those of us that have been there a while also stepped in and helped.
So far,no actual injuries,but there have been a few mishaps that with a little bad luck,could have been catastrophic. Thanks to the impeccable efforts of the old instructor,and good stuff from the new guy,I have been able to escape moderate injury totally,and I can still count on one hand the number of times I embarassed myself. I only started an out of gear mill 3 times,one of those is our newest Sharp manual,which seems to have caught everyone off guard at least once,the lever has a burr or something not right with it.
I got a too lengthy t-shirt wrapped around the feed rod on the Kingston lathe,but not bad enough to hurt myself.
My only real crash was about a .015 bite out of both vise jaws on the Haas mill.
I should have stood up and protested and not taken the instructions I was given,and as a result I used a 3/8 end mill to make a part where a 1/4 or 5/16 would have been better suited,and took a nice circular chunk out of both sides,about an inch and a half in from the right edge.
The vise was a fairly old Kurt.
The only time I did anything to myself was in helping another student drill/bore a 2" hole in a lathe, I was standing on the other side,and applying cutting oil to his 1.625 drill. He stopped the spindle,and backed the tailstock up some,but not far enough. I leaned over to look down in the hole in the part,and leaned in far enough I laid my forehead on the rather hot drill,and even heard it sizzle.
Nothing permanent,just a 1/2 x 3/4 light blister and brown spot that lasted a week.
The new guy has radically improved the CNC part of the course,in this aspect. The old guy had you manually g-coding a Emco Compact desktop lathe and mill,making preselected chess pieces out of machineable wax,and for more complicated stuff,he had you use a program called N-Vision,which took your code and ran it in a virtual environment,eliminating real crashes,but since the program didn't have a conversational panel,you didn't get the feel of actual machine interface time or technique. I can totally see his point.
The new guy got our Haas lathe and mill running,and also got the school a educational version of GibbsCAM,so you can see the toolpath,what properly formatted programs look like,etc.
He said people would be hands-on with the Haas,and we were. More on this to follow.
Now here's the problems. Back before the instructor change,you didn't touch a screwdriver,much less run a lathe,mill or surface grinder until he was sure you not only knew what was what (he was very strong on bookwork),but that you also displayed at least moderate maturity and responsibility,
Now,and partly because they have so many students and not enough machines,he has changed the course somewhat.
It used to be that your first real shop work was simple layouts,laying scribed lines,and use of a vernier height gage. The first projects were a drill point gage,a t-slot cleaner,and the body of what eventually becomes your c-clamp.
Now,sometimes within a day or 2 of you taking the mechanical aptitude test and watching the safety videos and several videos that relate the history and future of machining,you are grinding cold-rolled square stock into practice lathe tools,then your first HSS blank. I didn't get to do mine until about 3 solid months of bookwork. The newer guys and especially the HS kids seem to enjoy this. I think it's going to eventually get someone hurt.
Now,the first project after you grind your first tool,is a 2 piece reversible tap handle,and 2 knurled screws. This is made on a manual lathe from a length of 15/16 cold rolled rod,knurled with a radiused end,meaning that the center-drill holes are cut out,the big end is then cut down to a 5/8 square in a mill,with a small and a big 45 degree notch,x 2. The square is milled,then surface ground square.
That project would be pretty easy to make starting with square stock and a properly indicated 4-jaw. Instead of properly relating the importance of chip control,proper knurling,speeds/feeds,indicating a 4 jaw,and even safety issues such as NOT confusing the feed lever with the threading lever,etc,he's turning these guys loose on not only a lathe but a mill as well,in the first week? Let's not even take into consideration the destruction a grinder crash can cause.
There were at least 15 incidents where myself,or another experienced student had to step in and show them proper setup techniques,and a couple others where a near-miss took place before he stepped in,when he should have been there in the first place. He either needs to double his efforts,or have the front office hire an assistant.
EVERY student in the class up until yesterday has told me at some point or another,that I have given them more and higher quality help than the guy being paid to teach it.
I was his unofficial assistant for the whole time he's been there. He's really gonna be spread thin now with 25 in there before long.
I spent a LOT of time making stuff for the auto and IM courses,time that could have been spent giving me one-on-one instruction on stuff like g-code,but I came to the following conclusion.
He always seemed to be pushing me to look stuff up,experiment,and maybe fumble a couple times. I came to realize that in a lot of those cases,he SIMPLY DIDN'T KNOW.
For example,anyone that has gotten to the point of doing the trig parts of the math book,you either got help from one of the older students,or you figured it out ON YOUR OWN. I asked a question about inverse functions very soon after he came in,and got a blank stare. I never asked again,I did the last 6 chapters of the math book on my own,other than a .pdf copy of the old guy's math book we pass around,but it only covers the last 1/2.
As far as CNC,I taught myself how to run the Haas TL-1 and TM-1. The only advice I was given was to make sure I read the dadgum manual,and don't burn up inserts.
To this point,the new guy has NEVER ran a program on either of those machines that didn't come from GibbsCAM. He tried to use the IPS system to mill a slot,and asked me to step in. Early on in my involvement with the Haas mill,he called HIS SON
,who has graduated the Advanced T+D class at a different school,to show me the ropes of touching off with the jog wheel,set the work offsets,and the Z height. I swear,he showed me more in that one 60 minute conversation,than his dad did in 6 friggin' months.
On the subject of GibbsCAM. When we first got it last November,I was in a position to graduate at the end of December. He asked me if I would be willing to stay an extra session,to learn it,and possibly pick up an additional skill/certification that would help me find a nice job. I voiced my concern about the financial aid,and he got me an extension. What he didn't get,however was enough training in it himself to be able to teach me much. I played with the program and figured out about the same amount of stuff he showed me at first. He went places for training,and the stuff he showed me was maybe 1 notch over my head.
The administration is MAKING him take a college-level algebra course online,followed by a college level trig course. The old guy not only had both of those,but a true GIFT in being able to relate it to kids that weren't even paying attention.
Another couple positive notes,there is ZERO horseplay,and the shop itself is the cleanest I've ever seen it. He also got me signed up for a online Haas lathe and mill course which will produce an additional certification each,with the certs coming from Haas itself. The nice part about these is that even with me having graduated,I can do these at home,at my own pace.
Now,having graduated,I haven't found a single place within 100 miles that is hiring entry-level machinists,everyone wants Journeyman T+Diemaker-level experience. The only local shop that might give me a shot is run by a crazy,tightwad old man and with child support on 2 kids,I can't afford to do this kind of work for 8 bucks an hour.
Sorry for the incredibly long post,but I've been gathering my thoughts for weeks now,so here they are.
