BobCAD and CSMIO Rigid Tapping
« on: January 04, 2015, 05:22:17 AM »
If anyone uses BobCAD and the IP-S or IP-A (with Enc module) and intends to do rigid tapping then I have altered my post processor to put out suitable code for the M84 macro.
I have it working but am still tweaking it to try and make things a bit better.
At the moment each hole that is to be tapped has to be a seperate operation, this is because the M84 macro does not recognise the canned cycle format for multiple holes. Or at least I don't think it does, I am not at a machine now so can't be 100% certain but I seem to remember I had to previously do seperate M84's for each hole.

Anyway what I hope to manage is to make it so BobCAD will output code individually for each hole by using only 1 tapping operation. Problem is I am not great at VB so I may not manage.

As previously said I have it working using multiple operations, so if anyone wants to alter their PP just shout and I can let you know the lines that need altered in your PP.

I use Bobcad in Solidworks.
I started to modify the post processor.

A test tapping 4 holes, output the nc below.
I have not tried this on the machine yet.

I have not tested it but I dont think the above code will work, let me know if it does though.

I have not been succesful in making BobCAD output multiple M84 lines from the one operation :(
Its not that big a deal though as its simple to copy and paste a single threading operation, all you then have to do is choose the new hole geometry and compute.


Not sure how you are getting the code but I presume you are using Programme Blocks, if so then you can use the format to limit the decimal places.
