#### Defining Topography Data

The Topography tab is used to define all values necessary for the description of topography measurement.

Topography measurement uses single point probing to take measurements. All probing points and the machine movement is generated automatically by PC-DMIS Bevel Gear.

Measurement Area

- Flank Selection: Select whether the Concave Flanks, Convex Flanks or Both Flanks will be measured.

- Number of Teeth: This determines which teeth will be measured. This value is required. For example a value of 1/3/6/8 will measure teeth 1, 3, 6, and 8. Type "*" to measure all teeth.

Evaluation Area

- Define evaluation parameters now: If you want to define evaluation parameters, select this value and the evaluation options will be available for editing.

- Plot Magnification: This value is used to define magnification scale for the created report in plot server. If you specify ‘0’, the evaluation is carried out, but no plot output will be created; however, the evaluation parameters are stored in the measurement result.

Tolerances

- Total deviation: Defines the total tolerance for all grid points.

- Line at face: Defines the tolerance for the face line.

- Line at root: Defines the tolerance for the root line.

- Profile at toe: Defines the tolerance for the profile at the toe line.

- Profile at heel: Defines the tolerance for the profile at the heel line.

The graphic below provides an example of the topography tolerances and shows how the tolerance values are reported in the footer.
