Backplot cycle times way off

[left coast lefty]

5 spot drills, less than 1 minute actual time is showing 42 minutes. 

Searched the forum and googled but can't find anything. 

Thanks in advance.

I've seen 2 things make this happen...

1.  Make sure your feedrate is entered as IPM and FPT

or

2. In you machine def make sure your machines rapid values are set appropriately

If it is on a rotary unit with Inverse feed rates it can also be way off.

Mine does this if I have a dwell value entered.

Dwell, the wrong dwell increment can change the time calculation, say .3 seconds vs 300 milliseconds.

Theres still no way to enter an average tool change time into the backplot time calculations is there?

Im not sure if this has an effect or not,

Goto Machine Definition, in machine Configuration expand Tool Changer Group

Right click on Automatic Tool Changer - Properties there are some time values that can be altered.

Awesome. I just played around with this and the tool change time entered is showing up in the backplot time. Thanks for posting!

For some reason the time to index between adjacent tool pockets does not seem to be changing estimated time. Shame i cant get this to work, this is a weak point on my machine. Very slow between pockets. Any idea why it would be not working?

I have no idea really, you mean not working in Mastercam or your machine?

The index time is not being added to backplot. Only the toolchange time is. I've tried the various indexing options in drop down but nothing makes any difference. 

Machine works fine. Shes Just a little slow between pockets.

Just me?

The tool change time "should" include your indexing time.....it's more akin to your chip to chip time

Are those rapid or feed moves?

If the machine doesn't get up to full rapid speed in short distances it can mess your time up for sure, like if it's supposed to be moving at f1000 and it's doing f200 or something

If you look at the screenshot posted above there is a blank for indexing time, time to the next pocket. Im thinking it should be able to add extra time here in case you change from tool 1 to say tool 12. That takes a lot of time on my machine. But its not showing up in the backplot time unfortunately. 

Yeah we checked chip to chip time today and entered that value into mastercam.

If you use pre-staged tooling then the time between indexing to different tools is negated as the next tool will already be waiting.
