Honeysuckle MDA is a three-dimensional design software developed by Chinese engineers, part of the national 863 High-Tech Development Program. It integrates advanced geometric modeling capabilities by using the ACIS kernel from Spatial Corporation, which is widely recognized as one of the most reliable and powerful 3D modeling engines globally. Over 170 commercial CAD/CAM applications, including Autodesk's MDT, rely on ACIS for their core geometric operations, with more than a million users worldwide.
In 2000, under the support of the Tianjin Science and Technology Commission, Honeysuckle MDA2000 Enterprise Edition was introduced to over 123 companies in Tianjin across mechanical, automotive, and motorcycle industries. A total of 200 software licenses were distributed, and all users received professional training, leading to high satisfaction due to its user-friendly interface and robust functionality.
Honeysuckle MDA2000 offers a comprehensive set of tools for parametric feature design, including part design, assembly design, engineering drawing creation, advanced surface modeling, standard parts library, and realistic rendering. Users can create 3D solid models, generate engineering drawings, and integrate with CNC machining systems. The software also supports simulation, analysis, and secondary development, making it a versatile platform for CAD/CAM integration in China.
**First, creating a gear using Honeysuckle MDA2000:**
The involute curve is defined by the following equations:
- $ r = \frac{R}{\cos(t)} $ (where $ t \neq 0 $, R is the base circle radius)
- $ \theta = \frac{\sin(t)}{\cos(t)} - t $
- $ z = 0 $
For a helical gear with modulus $ m = 2 $, number of teeth $ Z = 30 $, pressure angle $ \alpha = 20^\circ $, and helix angle $ \beta = 10^\circ $, the parameters are:
1. Pitch circle diameter: $ d = m \times Z = 60 $
2. Addendum circle: $ da = m \times (Z + 2) = 64 $
3. Dedendum circle: $ df = m \times (Z - 2.5) = 55 $
4. Base circle: $ db = d \times \cos(\alpha) = 56.38 $
5. Base tooth thickness angle: $ \theta = \frac{180}{\pi} + 2 \left( \tan(\alpha) \times \frac{180}{\pi} - \alpha \right) = 7.708^\circ $
The angle between two teeth: $ \beta = \frac{360}{Z} = 12^\circ $, and the base tooth center angle: $ \gamma = \beta - \theta = 4.292^\circ $
**Second, step-by-step creation process in Honeysuckle MDA2000:**
1. Create a φ64 × 10 cylinder on DTM2.
2. Use the "Tools → Sketch Features → Function Curves" command on plane 3, input the equation: $ r = 28.19 / \cos(t) $, $ \theta = \sin(t)/\cos(t) - t $, $ z = 0 $. Set start parameter to 0.0001 and end parameter to 0.5.
3. Draw an auxiliary axis on DTM3 at an angle of 4.292° relative to reference axis 1.
4. Repeat step 2, using the previously created line as the x-axis.
5. Draw a circle with center at origin and diameter φ55 on DTM3, then trim the excess portion.
6. Generate a new reference plane and axis, then use the "Surface → Stretch Surface" command to create a surface by extruding along the selected curve.
7. Perform a surface subtraction operation to form the helical tooth groove, then apply a circular pattern of 12° × 30 to complete the helical gear.
Through these steps, Honeysuckle MDA2000 enables precise and efficient creation of complex mechanical components, showcasing its power and flexibility in 3D design and manufacturing.
