CAD Dialog

The absolute flexibility makes the difference

The easy to use CAD dialog allows the user to enter all important and relevant parameters defining his gear wheel, such as gear module, number of teeth, helix angle and so on.... The parameter values, entered into the dialog box, form the base of precise gear pair calculation.

The parameters may be controlled in different ways. You may compare the values calculated by the CAD dialog with your given values in the drawing, or visually check the gear pair's engaging motion in high accuracy display mode, or you may use the integrated 3D simulation, which is based on the same precise data that will be sent later to the milling machine in the workshop.

Easy parameter input by predetermined masks. In the beginning, one enters the basic data of the gear wheels into the designated input fields, as module, helix angle, etc. On demand, each input field displays an explaining text with graphic.

The navigation bar at the upper border of the mask is divided into several tabs. These tabs organize all important CAD functions and make it easy to enter modifications if necessary.

In a second step the protuberance will be defined. This can be done by a standard reference profile which fixes the parameters predefined by DIN standards. Or you may choose to enter and control all important parameters such as angle, radius and height yourself. Furthermore, you may define a tip chamfer with defined angle and distance, easy to mill using the InvoMilling™ procedure, and as a result a great saving of time.

The protuberance is a useful tool to avoid e.g. abrasive burning. In addition, a protuberance is very convenient for leaving a defined allowance on the flanks, to compensate material distortion produced by hardening.

Define corrections exactly. Flank corrections (width crowning, height crowning, tip relief, foot relief) play an important role for gear machining. On one side, flank corrections may be introduced to minimize the noise of the rotating gear pair, and on the other side they may equalize an imbalance of power.

Each type of gear is based on specific parameters, which must comply with different standards. In addition, a variety of corrections exist for the tooth flanks. EUKLID GearCAM provides a simple way to enter user data and save any state of a project without loss of accuracy. Among other possibilities, simulation presents perhaps one of the best ways to check your input data.

Input masks for flank corrections: The user friendly input mask allows even a beginner to find his way, even if flank corrections are a complex issue. The input mask allows each flank to be adjusted individually, providing a comfortable way to enter different correction values for load and rear flanks.

Furthermore, one may adjust each side of a double helical or herringbone gear individually. You may even add as many corrections as you like, one after the other. The corrections are transferred one-to-one to the involute and may be checked via simulation or visual control of the engaging flanks, as shown in the next figure.
