 hole Ruleset, ream or no ream

Hi guys

I have one question. I have a platte with two holes. One diameter is 20 and the second is 20H7. I want to drill the two holes with a hole rule set.
One hole must drilled with a diameter 20, and the the second must drilled with 19.7 and reamed with 20.

And now my question. Where did VX decide that the hole will ream or not? What settings are necessary in the hole generator and rules for reaming?

I attache a small example. The green hole should 20 and the blue 20H7.

Best regards T Snoopy

Hello Snoopy

Firstly, you need to ensure that your tool library has the cutters required, a D19.7 drill is not listed in VX's sample library.

It ought to be possible but I cannot see a way to get a Hole Rule Set to pick the correct D19.7 drill and follow with a D20 Ream. The holes can be added as separate features. This way, it is possible to manually define the operations and pick the exact cutters for the job.

Hi Thomas,

Have you tried altering the hole tolerance?

Hi Chris, Hi Bob

my tool-libary is okay. I have a other one. There is a drill with 19.7.
Maybe some user of the forum have trouble with german text and commands so I generate the example in an english VX-version and not in German VX-version.
There I only have looked on the two holes, if they a reamed or not.

Anyway the english libary is not correct. All Reamingtools have a wrong diameter for the pre drill operation. But that is not the theme.

I tested different tolerances by the "hole feature" and by the "rules for reaming". But no positive result.

Have you any idea?

Hi Snoopy

You can add a hole as a feature to the tactic (Hole Rule Set) and then of course use the tolerance values to determine the group of tools selected, in the same way as I have done with the "manual" solution. To have the Dia 19.7 drill selected by the Rule Set, it must be the pre-req tool in the Tool Properties of the reamer.

Example file attached, which has it's own mini tool library including a 19.7 drill and a ream with that drill as it's pre-req. Thanks to the developer for explaining how this is set up.

Hello

It works. You must define by the hole generator in the 3D-Part:
D20 = Toleranz +0.01 and - 0.01
D20H7 = Toleranz +0.003 and -0.003

Have a look to attached file

Our Tool-libary must be okay.

Thanks Enrico for his help, he works already longer thereby.

Best regards Snoopy
