How much time to program this part?

[Daniel M]

Just curious how long you guys would estimate to do this part. Not looking for any record setters, just normal programming pace (and the usual interuptions)

 

Ready, GO!

 

 

Mat'l is 4340M. Rough prior to heat treat then finish. Bearing bores are +/-.0005 dia and location is tight! Consider the rest of the part +/- .007". There are two angled holes for grease fittings 2pl at the yoke side (thru one side). Programmer designs tooling and dreams up machining strategy, orders cutters and models the part from print views drawn in 1972 (nice huh?).

 

Now the machine is a newer Fadal. Not exactly a steel machine but does ok. Max cutter dia for roughing is .75dia. You can use insertables but probably won't go biggger than 1.5dia" and .2"axial cut.

 

A 4axis vertical is used to finish the bores and grease fitting holes.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

....Thanks fella's!

...forgot to mention .03-.06rad edge breaks all around for shot peen.

I have an hourly rate

[Goldorak]

start from a casting or a solid block ?

[Daniel M]

Solid Block.

Daniel,

 

Are you asking how many hours to do the Mastercam program or the number of machining hours?

 

I think asking how many hours to program is a loaded question.

[Daniel M]

Yeah, I was asking how long to program.

 

I'm looking at 1)dovetail 2)rough top 3)rough bottom. 4)4ax rough bores 5)finish top and profile. 6)finish bottom 7)4ax finish bores 8)4ax finish grease ftg hole 1 9)4ax finish grease ftg hole 2.

 

2 programs for tooling.

 

I'm guessing about 60 hrs. total my time.

What type of a machine? What taper? What kind of tooling?

Yikes! Yes I would also guess 40-60 hours while contending with usual distractions and what not. If you end up making the part, be sure to post pictures of the final product! Looks like a fun one.

[htm01]

a 6 yr old with Feature Based Machining could do that in 15 min.

[Daniel M]

Yeah, it works on the computer just fine. I dont know what the problem is on the floor. Try reloading the program!

 

[Daniel M]

Guess I need to check my emastercam etiquette.

 

Sorry for the loaded question guys.

 

Have a nice weekend.

[Colin Gilchrist]

What kind of quantity Dan? Is machine time a concern? I know it always is, but if you only have to do a few you can cut the programming time way down. You just have to live with the extra moves it is going to make. You said 4330 right? Get some coated carbide and have fun...

So are you saying 60 hours to program + manufacture or just program?

 

I do not see 1 1/2 weeks work in that part.

It depends on the machinery available.

A part like that requires more fixturing if you

are restricted to a light weight VTL with a 4th

axis rotatary table.

You have a lot more options with a 50 taper horizontal or a 5 axis table/table setup.

It also depends on whether you're building

2 parts or 200

and

will you have skilled machinist or button pushers?

 

A skilled machinist/programmer in a well tooled

prototype shop could easily knock

a couple of these out in a week and a half.

 

Designing and programming a manufacturing proccess with

all the required part and fixture NC files, in- proccess part and fixture sketches

etc etc etc.. is a whole lot of work

THIS is the part most customers/engineers/clients seem to forget when they shriek in horror at a time estimate.

[TuxedoMask]

I'd honestly say I could program that part in less then 20 hours if given the model, but that's also a really rough estimate.

If prints are legible and no missing information my quote would be:

6hrs to Model

10hrs fixture design and program

15 hrs of programming.

 

The rest shop owner could handle.

[mig]

I agree with some one who say 20-25 hrs total time

[Bruce Caulley]

I'm with Mig. Even needing multiple ops on a VTL, 20ish hours should do it, including fixturing. If the qty was higher, add another shift after proveout for optimisation.

To be totally honest

Usually when I getting this kind of jobs , I programming when machine cutting ( I running machine too ) . As example : program roughing of first side - cut . While cutting program next side etc . So in reality programming cost even less .

Btw here is our company website . Is not complytely done yeat , but......

Nice part !

 

I think also about 40hours to program.

 

Can you share and upload the part ?

It's very interesting how long it really takes time to program.

What about everyone how want, can program it and show the results here ?

It will be also interest what strategy is used.

[TK-32™]

I'd be scared just to show images of a part like that on an open forum.

Maybe it just me and my paranoia.

[Daniel M]

Yeah. Someone might use it for a boat anchor or something.

 

I guess I won't freak anyone out and say that its an aerospace part. Oh, wait...

 

Hey you make it and use it for whatever you want.

 

 

Next images I show will be SI girls. You appreciate that right?

 

Starting this thread was a mistake. Won't happen again. Have a happy non-paraniod week.
