Okuma G131

[TORQUE]

Hello all, 

I'm trying to incorporate okuma high speed functions into my post. mpmaster

code example:

G131 F1000. E0.003

max feed and tolerance held.

G130 turns it off.

I'm using Misc values, Misc reals 1 and 2 (the factory spot for high speed functions)

I converted MR1 #3 to use G131 F1000. and the cancel for G130 which work fine and position code in proper spot.

My issue is the E value (mr2) is always a whole number not a decimal. (I have tried lots but never get the desired output or I create an error)

After typing all of this I'm wondering if I can only use whole numbers for Mics Reals?

Thank for any help provided. Have a great weekend ill be back on Monday.

Real Numbers, by definition, are Decimal Values in the NCI File. (The 'Misc Integers', are only whole integer numbers.) So you have to be using 'mr1$', 'mr2$', and 'mr3$'.

You must use Format Assignment Lines to format the "number output" for a decimal. So you need to add formatting for 'mr2$' (Decimal, 4 place), to get the Corner Rounding value to come out properly.

Also, watch where you are setting the values.

For the 1st Tool Change, you should get the 1st operation's values. But after that, 'Pretract' is called at the start of the next tool change. So sometimes you can be an Op ahead/behind. Just be sure you aren't processing the previous/next Op's values during your testing...

For MPMaster, they have a mechanism built into that Post to avoid this issue.

See 'plast'.

They record the 'last MR values' for MR1 and MR2, in the 'plast' Post Block.

Thank-you very much Colin, 

I did some searching for Format Assignment Lines,  I ended up finding one for your other posts describing how they work. changed the 4 to 2 and BAM! I got a decimal.

I added in mr3 and its all tied up with a bow on top.

Thank you for you Help.

This is the code I like to use for setting up Hi-Cut in my posts. Code below uses mi4$ as a toggle to output on. mr1$-mi3$ are for extended commands within the G131 line.

Enjoy,
