    Best way to create 1/8" holes in 1" steel plate?

    And with the last poster, I'd like to see dimensions of the parts. And second question is why? Why to all of it, why the fussy entry exit, why the finish etc. All the holes will need to be spotted, and small through spindle coolant Guhring drills are the way to go and will give good life...

    The best way to protect a bolt from loosening?

    Also a piece of steel with the correct hex and either bolt it on over the bolt, or tack weld it, to remove just cut the welds off to remove the lock plate.

    why do we leave Tags when we do CNC machinig

    Pretty simple stuff, if its cut off completely then when the second to the last one is cut, the part will just flap around when the last one is cut off, with the possibility of ruining the part and the cutter. If there is a way to clamp it for tab removal then yes you can fully machine it then...

    Where to Find Tolerancing Resources for Mechanical/Design Engineers

    Ridiculous unnecessary close tolerances are costly, like for bolt hole locations when the better thing to do is to open up the hole to accommodate an increased tolerance range. Some things need to be close, but having a cad system default on some stupid small tolerance is senseless. Any...

    Drilling tellurium copper, 145 copper

    Tellurium ? Must be expensive stuff since its a very rare element. Like all machining don't over do the surface speed, or push it too hard, if the highspeed breaks down too fast use carbide.

    The best way to protect a bolt from loosening?

    Loctite it or if it doesn't need to come out ever, then weld it.

    We are experiencing short tool life turning stellite materials

    Tool material carbide. And just like everything else in machining fast surface speeds kill cutters, intermittent cuts kill cutters. So the choice is fast and no tool life, or slow and easy and have tool life.

    Machine Part Work Life

    What kind of machine parts? Machine tools? Or what? If it is machine tools that would be close to impossible to determine. Why, because too many variables, like are you using the default speed parameters or did you speed them up or slow them down? What kind of loads are you putting on the...

    Math Question : Writing Machine Macro

    If it is just 4 axis horizontal machine, and you wish to use the same zero point that you find on the setup position then of course just X and Z are the calculated axis. First you would calculate where that point is in the zero tombstone face position of setup, and then you will know the Z...

    MACHINING A SOCKET DRIVER

    Can this be made by CNC?

    I worked at a proto type shop and we did that sort of thing all the time. It can take many hours to hemstitch with a small diameter ball nose cutter to do it though. You can also use SLA rapid proto typing or 3 d printing too.

    Resources for Creative workholding and fixturing in CNC Machining

    Find a good machinist and or tool maker. Engineers that are not former machinists just can't grasp it, as its a different world when it comes to machining, just not the same as on paper or on a computer screen.

    End Mill Jamming in Aluminum during CNC milling Attempts

    If the material is gumming up the flutes going faster does no good. You will need some coolant, even cutting oil is better than nothing. I started machining in the late 60's, believe me there are sometimes when you have to cut aluminum like it is Inconel or 321 stainless, it depends on the set...

    Turn or mill this part? (or machine as two pieces and join somehow)

    2 parts and EB weld it.

    how would a machinist program this?

    The cnc programmer would import your cad drawing and use it to machine the part. If it is done by manual G code programming all the tangent points that is the angles and start and stop points need to be calculated. If that is how it is to be programmed it will help a bunch showing those...

    machining witness or reference point explanation;

    24 x 12 feet? I doubt there is a machine that can cut anything that size to that tolerance. And besides if it is cut to that the difficult part is the realinement when it is taken off the machines table. The simple act of lifting it will distort it like crazy. You will need a specialty...

    Gas Turbine Air Inlet Filtration dP - back-to-back filters.

    Since turbines are such an air driven engine, and such huge amount of CFM is involved, and of course depending on dirt conditions,(I suppose is bad else you wouldn't consider filters) the filters will need constant attention and cleaning. It will be interesting how much they derate the engine...

    Improper G code from MasterCAM X5 to Bridgeport Torq-Cut 22

    There are different post processors for the various types of controls in master cam. Select the correct one for the machine your using.

    Discoloration on machined surface

    Something in the coolant causing a reaction? Have you recently cut cast iron? Or some material that is brownish?

    Hole inside a plate. How to mill?

    Hmmm unless it is a part for microwave.
