Calypso is adding way more bonus to position tolerance on hole that is oversized.

For instance hole diameter is .500 ±.005. Position is .010. Lets say hole is machined to .550. Calypso will give an extra .055 bonus to the position.

I did followed the direction on here to have the separate MMC and LLC callout not shown in the report. Don't know if that messed up the bonus allowance.

Extras-settings-measurements-MMC/LMC. You can limit it to size.

Thank you so much. That should of have been the default setting on Calypso.

Most people prefer the mechanical gage setting.

In high volume manufacturing environments i.e. automotive, it is common to use mechanical gages to check the part. Not so much in job shops or lower volume shops. The operator puts the part on a fixture to check the position of the holes. If it goes, it's good. If it doesn't go, it's bad. However, the gage can't detect if the hole is oversize. Then, the operator will check the hole sizes with pins and will reject a part if the no-go goes. This is how you get correlation with the CMM and the floor inspection method.

It is my opinion that since Calypso is so deeply involved with automotive, it would make sense the mechanical gage option is the default. It is also my opinion that Calypso is a tool box and the user is responsible for knowing where the tools are and which tools to use.

No. I think it's because of your follow-up comment about automotive where at the end of the day fit/function rules measured results.

Oh snap! 🤣
Interesting take. My argument would be that the location should be within spec, given that the hole diameter should not exceed the limitations of size; therefore, the mechanical gage option should not be the default, as allowing the no-go gage to pass when the hole is over spec is an inherent flaw of the mechanical gage.
With that being said, I can see both sides: Limiting to size ensures ideal positions of hole diameters; while using the mechanical gage option ensures fit & function. It all depends on what is deemed most important.

Here in New England, there aren't a lot of automotive shops any more. Not saying there aren't any but I've only done a handful of demos in my 13+ years here at Methods. Mostly medical, aerospace and, of course, GUNS.... lol
