## Defining Master Flank Data

The Master Flank Parameters dialog box, accessed from the Gear Measurement Setup dialog box, allows you to provides additional settings to measure a Master Flank of your bevel gear. If you don't have a Gleason File, you should measure the Master Flank before you measure your gear. The calculation of the Master Flank uses an average from all measured flanks.

Select the Measure | Master Flank menu option to open the Gear Measurement Setup dialog box which includes the MasterFlank Setting button.

Master Flank Parameters dialog box

Number of Teeth to Measure: Determines the number of teeth that will be measured to define the Master Flank. The teeth measured will be as close to equally spaced around the gear as possible starting with tooth #1. The default value is 4.

Teeth to be measured: This automatically lists the teeth that will be measured based on the Number of Teeth to Measure and the total Number of Teeth specified on the Parameters tab. This value is required. For example a value of 1,11,22,32 will measure tooth #1, #11, #22, and #32.

Flank selection: Select whether the concave flank (CC Flank), the convex flank (CV Flank), or Both Flanks will be measured.

CV (Convex) Flank and CC (Concave) Flank Areas

Number of lines: Specify the number of lines parallel to the tip of the tooth. A minimum of 4 is required for this value. See D in the example below (the dotted green horizontal lines).

Number of columns: Specify the number of lines parallel to the tooth profile. A minimum of 4 is required for this value. See B in the example below (the solid black vertical lines).

Line index of Reference Point: Provides the line at which the reference point is located where it intersects the column index. See C in the example below.

Column index of Reference Point: Provides the column at which the reference point is located where it intersects the line index. See C the example below.

Example showing how points are to be measured on the Master Flank
A - Positive Z axis
B - Columns parallel to the tooth profile
C - Reference point (line index=4, column index=3)
D - Lines parallel to the tip of the tooth
E - XY plane

File Name: Click Browse to specify the location to which the Gleason-Formatted File will be saved. This opens a Save As dialog box. Type the name of the file in the File Name box and click Save. You may also type the path and file name in the File Name box.
