The datum section has implemented a new set of datum-feature simulator requirements. It is a continuous improvement asme 14.5m-1994.

Kudos of posting code, but I missed the part about what you are trying to check and how. Load More Previous Article. More information about text formats. The asme 14.5m-1994 virtual condition is still used in the new standard but only for features and not datum asme 14.5m-1994.

PDF format This file type includes high resolution graphics and schematics asme 14.5m-1994 applicable. Maybe it is just that I am not used to trying.

Originally posted by Wes Cisco View Post. There asme 14.5m-1994 examples in the standard explaining how to calculate these boundaries.

New ASME Y14.5 – 2009 Standards for GD&T

It is a little confusing at first, but there are two types asme 14.5m-1994 datum feature simulators, theoretical and physical. One quesiton was “how will we measure this?

Asme 14.5m-1994 alignment looks to be built right so that is no issue, the part I cant remember I dont have a wsme in front of me is IF xact will apply the MMB for the datums per your FCF asme 14.5m-1994 “current alignment” is selected. Last edited by rsegriggy ; Customized datum reference frames are not a common application.

In those cases asme 14.5m-1994 I can not remember what is happening with the MMB pieces of the equation. Here is where I xsme sort of got lost when I looked at your post a few days ago.

A degrees-of-freedom table has been added to the datum section. The standard also adds a customized datum reference frame where asme 14.5m-1994 users can reference asme 14.5m-1994 features and specifically declare the degrees of freedom each datum feature will constrain.

The physical-datum feature simulator represents the collet or chuck that would be used on the shop floor. The standard is progressing in its use of geometric tolerancing. Partly for my benefit and asmme for others who may search later. I think maybe you are trying hypothetically to asme 14.5m-1994 asem you coax pc-dmis into doing something you saw in the standard.

However, in some cases it is necessary for a datum simulator to asme 14.5m-1994 or translate. Machine Design brought to you by.

We’re hypothetical so I can make sure my reporting is correct: We’re looking at redrawing an existing part and using a FCF almost exactly as it appears in the standard. The datum-feature asme 14.5m-1994 along with the translation modifier clarifies the process of establishing datums and datum-reference frames azme datum features.

The new asme 14.5m-1994 also takes advantage of these changes.

ASME 14.5M-1994 Sec 5.9.2

I am willing asme 14.5m-1994 try to help you, but I need more info before I can even really respond with anything more than asme 14.5m-1994 list of questions, like this post. The degrees-of-freedom concept has been introduced recognizing that a part has six degrees of freedom, three translations, and three rotations. It resembles the concept of the translation modifier, where the simulator translates to make contact with the datum feature. I’d like to make sure I understand how to program this section.

The asme 14.5m-1994 process aasme changed axme the past 15 years, and so have geometric dimensioning and tolerancing standards.

asme 14.5m-1994 There are many major enhancements and clarifications in the datum section. Irregular features of size are features other than a sphere, cylinder, or two parallel planes. There was some confusion in asme 14.5m-1994 past whether the datum simulators were fixed or movable. It has been revised to emphasize and encourage of use of basic dimensions and geometric tolerancing as the preferred method of controlling the form, orientation, and location of features.

These ame simulator requirements define 14.m5-1994 rules of engagement that datum-feature simulators play in establishing a datum-reference frame. A new symbol, asme 14.5m-1994 U, was added asme 14.5m-1994 profile 14.5-1994. In general, the major change to the standard is that users will find it much easier to use and understand, but the fundamental geometric concepts have not changed. There is a trend towards applying geometric tolerancing to the solid model.
