Slick site, but the dam metric system! I'm too entrenched in the stone age to bother with all the darn conversions.

 

Thanks anyway

Will the USA go Metric one day???

[Brendan P]

When I was in the 3rd. grade the told me it would.

I'm still waiting.

 

Ps. 1 time I asked a guy at work "How many 1/8's are in an inch"?

He said "16".

 

I'm not too sure if America is ready for the metric system!

Should've asked how many 1/8's in an ounce.

Woulda got it right off the bat.

[Brendan P]

Yea,you got that right!

 

Bucket teh used to have to count the lines on a ruler.

[Chris Rizzo]

Jim!

Reminds me of the college days (daze)! haha

Buckethead like the look of your bike,I also ride i have a new ZX9R road bike and a YZ426 dirt bike.

I have that CD..It works really well. Speeds and feeds seem to be pretty right too..

 

Just cut a 42HRC mould, and it worked great

Don't know... Right now I work with both, inch & metric. Metric system is much easier to understand especially if converting to inches is not an issue. One big draw back is that most of the tooling I own is inch so I still have to use my calculator and figure out where I am (operator intervention-just another way for a mistake to happen). One big advantage for using metric system is the machine tolerances; If the machine is set to metric, the tolerancing improves (.0001mm vs .0001in)

Prototyp belongs to the sandvik group. This data is similar to their CD-Rom Coroguide. Suggest that your local Sweede get you this information - I use it at least 4-7 times a quarter.

I'm thinking that unless your particular machine is repeatable to within .00005in, all you are doing by running it in metric mode with inch tooling is giving yourself an extra opportunity to make a mistake. Just becasue you can tell the spindle to go somewhere with five place precision dosn't mean that the spindle's resulting location is accurate to five places.

The problem that we encounterd here was that we had to hold +.0003/-.0000 (in) tolerance with an end mill. That is no problem on paper. Again with inch mode there was only .0003 to play with ( hard to split that up)... The machine holds the tolerance very well, but running it in metric mode gave us the flexibility to really tune it in just right. It has been working out very well for the past couple of years with no mistakes (knock on wood).

Well cool link but pretty much most of the time go by memoery and feel of what I think works, I look at it this way if the cutter burns up going to fast. If the material burns to going fast enough lol just kidding about that. I push it till I think the machine the set-up and tooling can handle and all of the feeds and speeds are good but nothing like knowing what your are looking to qand hearing to really help you get it the way you want.
