Easy GD&T Profile of a Surface[ Symbol, .

Because of this tolerance zone, the Profile of a Surface can control the feature's form, size, orientation, and sometimes even th location. It can be a good choice for parts that have a complex outer shape but a constant cross-section such as extrusions. Profile of a surface can often wind up being a catch-all for surface control. In other words, if you can't figure out how to control with ...

Profile tolerance of a surface - Engineering .

Profile tolerance of a surface is used to control the ideal form of a surface, which is defined by theoretically exact boxed dimensions and must be accompanied by a relative tolerance zone.The profile-tolerance zone, unless otherwise stated, is taken to be bilateral and equally disposed about its true-form surface.The tolerance value is equal to the diameter of spheres whose centre lines lie ...

Use Profile to create and modify extruded surfaces with maximum control over section transition and location. A profile is composed of one or more planar curves. It can have sharp bends and can be closed. If several profiles are used, they can have different shapes but must have a similar structure (segmentation between sharp bends or number of spans). Each profile can have an individual ...

Surface Profile Measurement by Replica Tape

Surface Profile Measurement by Replica Tape The surface profile measurement by replica tape (Press-O-Film or testex tape) is performed after sandblasting, i.e., SSPC-SP 10 (near-white metal blast cleaning), SSPC-SP 5 (white metal blast cleaning), etc. to make sure the sandblasted surface has the required profile as indicated in the customer coating specification.

GD&T Profile Definition | eMachineShop

In GD&T, profile tolerance defines a uniform boundary around a surface within which the elements of the surface must lie. Profile is a complex tolerance that simultaneously controls a feature's form, size, orientation, and sometimes location. Profile is a three-dimensional tolerance that applies in all directions regardless of the drawing view where the tolerance is specified.

PROFILE TOLERANCES - Cobanengineering

Profile tolerances can be applied either unilateral or bilateral. Profile tolerances can control the location, orientation, size and form of a feature. The profile elements are curved lines, straight lines, and areas. The actual profile of the surface can be defined by basic radii dimensions, coordinate dimensions, angular dimensions. MMC and ...

profile would be controlled to the tighter tolerance of .005. In Fig. 12-17, the lower segment of the ple single-segment feature control frame controls profile size, form, orientation perpendicular to datum feature A, and location to datum feature B within a .005-wide profile tolerance zone. In other words, the actual profile must fit inside the profile-refinement tolerance, be ...

What is profile of a surface Tolerance and how .

The true profile must be with basic dimension or be a planar surface. No modifier symbol may be displayed in the tolerance portion of the feature control frame. If the true profile is located with tolerance dimensions, the profile must be a refinement of the tolerance value of the dimensions.
