### Profile Tab

This tab lets you specify the required data for the measurement of the Profile
as well as the analysis parameters for each measurement. Profile measurement is optional; if you don’t want to measure the profile, deselect the Measure option.

Gear Definition dialog box – Profile tab for cylinder gears

Measure: When this check box is selected, the gear profile will be measured during the measurement process based on the parameters defined on the Profile tab.

Measurement Area

Number of Teeth to Measure: This value is the number of teeth of the gear on which you want to measure the profile. The teeth measured will be as close to equally spaced around the gear as possible starting with tooth #1. The default value is 4. Increasing or decreasing this value, will update the Teeth to be measured list according to the Number of Teeth specified on the Parameters tab.

Teeth to be measured: Click ... to open the Edit Tooth list to be measured dialog box.

Edit tooth list to be measured dialog box

Create the tooth list by typing each tooth number that will be included separated by a comma. The number of teeth listed should be the same as the Number of Teeth to Measure value. For example, if you want to measure the profile for Tooth #1, #8, #14, and #20 just input 1,8,14,20 in this edit box. This value will not affect segmented gears; however, be sure not to define a non-existing tooth number. Click OK to save the tooth list or Cancel to close without saving.

Profile on left or right flank: This list lets you specify the flank to measure. Available options are: Left, Right, and Both.

- For an external gear imagine you are standing on the center of the gear and looking forward at the gear's tooth. The left flank is on the left side of the tooth and the right flank is on the right side of the tooth.

- For an internal gear, imagine you are standing in the center of the hole and are looking at a space between two teeth. The left flank is on the left side of that space and the right flank is on the right side.

Start Diameter (near root): This value is the diameter of the circle which represents where the profile scan should start.

End Diameter (near tip): This value is the diameter of the circle which represents where the profile scan should end.

Z Coordinate of Profile Measurement: This is the Z coordinate value where the profile should be measured. This value is normally negative but positive values are allowed. This is not a depth value.

Evaluation Area

Start of Evaluation Range (near root): This diameter value determines where on the profile scan you want to begin the evaluation. You should use a value slightly larger than the profile start diameter value.

End of Evaluation Range (near tip): This diameter value determines where on the profile scan you want to end the evaluation. You should use a value slightly smaller than the profile end diameter value.

Magnification of Deviations (%): This value is a percentage that all errors will be magnified by for display in the analysis.

Magnification of Range (%) (Def. autom
): This value is percentage that all errors will be magnified by for display in the analysis. If you type a zero, PC-DMIS Gear calculates the value internally.

Tolerance of Profile Angle Dev. (fHα
): Provides the allowable deviation between two design profiles which intersect the mean profile at the end points of the evaluation range. Please see the appropriate gear standard for a definition of this value.

Tolerance of Total Profile Dev. (Fα
): Provides the allowable deviation between two design profiles which enclose the actual profile over the evaluation range. Please see the appropriate gear standard for a definition of this value.

Tolerance of Profile Form Dev. (ffα
): Provides the allowable deviation between two profiles parallel to the mean profile which enclose the actual profile over the evaluation range. Please see the appropriate gear standard for a definition of this value.

Tolerance of Profile Error (Vφ): Please see the appropriate standard for a definition of this value. This value is for the AGMA gear standard
only.

Evaluate Crowning: This value determines if crowning should be evaluated. If it is checked then crowning will be evaluated and if it is not checked then crowning will not be evaluated.

Minimum Crowning: Please see the appropriate gear standard for a definition of this value.

Maximum Crowning: Please see the appropriate gear standard for a definition of this value.

This button causes PC-DMIS Gear to use the values input on this tab as well as the Parameters tab to calculate the tolerances of the Pitch
and Runout
based on the standard specified.

Report Setting

Draw K-Chart: This check box determines whether or not the Tolerance K-Chart appears in the report. For a definition of the K-Chart, consult the gear standard.

Draw Grid Line: This check box determines whether or not grid lines are displayed in the report. Grid lines act as a ruler of sorts, indicating in the report how large the deviation is.

Define K-Chart: This button lets you define the parameters of the K-Chart for profile and helix/lead. See the "Define K-Chart" topic.
