I have X6

[newbie70]

Hi Members

 

I have X6 and will be switching to X7. I cannot find m/c simulation for lathe. Any tips on vericut software?

Do you currently have Vericut?

 

There is no Machsim for lathe in MC.

 

What lathe do you have?

Just wondering why you would need a sim for a lathe, unless it has multiple spindles and live tooling?

Well I used to work for a company before I quit my job. So am familiar with Okuma, Mori Seiki, Daewoo etc.

Since am a newbie, CAD/CAM is also new to me.

I don't have vericut software. But yeah, you're right there's no sim for lathe in MC.

The reason I need sim for lathe to know the machining time (Time based mode).

Any keys to set machining time for lathe in X6 or X7 under verify?

Mastercam back plot gives a time. I just add about 10% to that and I'm usually pretty close.

Thks R J. for the feedback. Will try with back plot.

[DODGERFAN]

Glad I can help. The reason I add 10% is because Mastercam back plot doesn't take tool changes into account.

That wouldn't be possible because every lathe changes tools at different speeds.

Hi R J

I installed X7 yesterday. I tried a stock of 110 dia. by 100 long using the margins. I plotted 3 steps with the min. being 30 dia.

My op. involved face, rough and finish tool paths. The feed time shows 1hr 21 min. which I think is wrong.

Really why? I have some 80" diameter parts and the run time on them is 22 hours for roughing on one area that is 4.7 deep x 2" wide at 9 RPMs that thing is going to take some. What RPMs are you running? Do the math your Circumference is X 3.14159. Take your feed in Per rev and figure out how many revolutions per minute you have programmed and what step over. Take .01 step over and going a distance of 1". That is means for every inch of travel the tool has covered 100 passes at 345" per pass. For every one inch of travel on a part with a 110 diameter the tool has traveled 34557.9" in distance take that number and divide it by your RPMs and you have an amount of time it will take to take the cut. Yes that distance decreases if you are going from a bigger diameter to a smaller diameters, but something that big depending on the speed and feed just may take that amount of time. Pretty basic math and I have found the X7 times on lathe to be pretty close.

Everything Ron says here is golden. Make sure you're speeds and feeds are correct to, makes a huge difference in the time.

You are working in mm not inches, right?

Good catch Ray was not thinking metric, and it were drawn in inches and used the wrong speeds and feeds then yes it all becomes relative.

I was thinking, if he's running a 110" dia and getting a 1:21 cycle time he's kickin arse. LOL

Yeah me too why I posted up what I did.

[newbie70]

Apologies members : That's correct I am working in metric. I tried with a stepover of 10mm on dia. It came down to 29min. which is still more.
