一、具体功能描述

HyGEARS软件是加拿大Involute Simulation Softwares Inc.的软件产品。此公司由Claude Gosselin博士创建，总部位于加拿大魁北克，是一个专业的齿轮设计和仿真软件开发商。

HyGEARS 是专业齿轮设计和加工仿真软件，它覆盖目前齿轮工业领域几乎所有的齿轮类型，它包括的主要功能：

（1）设计齿轮对：面铣式切制法锥齿轮(face milled spiral-bevel),准双曲面锥齿轮（hypoid）, 直锥齿轮（straight bevel）, 摆线齿锥齿轮（Cyclo-Palloid spiral-bevel gears）, 直齿锥齿轮（Coniflex ™）, 正齿轮（spur）, 斜齿轮（helical）, 小交角齿轮（Beveloid）, 人字齿（herringbone）和面齿轮（Face gears）;

（2）分析齿轮运动学（加载和不加载）：传动误差TE, 接触印痕Contact Pattern, 快速傅里叶FFT, 弯曲和接触应力Bending and Contact stresses等;

（3）研发和优化齿轮对运动学特性，通过特定的功能提高承载能力和操作平顺性。

（4）通过与通用加工机床CMM的输入/输出接口评估制造加工质量。

（5）使用多种加工方式在传统机床和5轴数控CnC机床上模拟齿轮切制，包括Face Mill, Dish type cutter (for Coniflex gears), Conical Side Milling Tool (or CoSIMT, such as made by Ingersoll Rand, Sandvik, PTR-TEC), End Mill and Ball Mill tool。

（6）使用集成的闭环过程，持续的使用CMM输出，确定机床修正参数，确保已制造的部分与设计相比在设定的公差范围内。

1. HyGEARS’ tooth flank generation and TCA calculations match Gleason’s CAGE and Klingelnberg’s KIMoS; therefore, the reference topography in HyGEARS is the exact tooth definition;

2.  HyGEARS designs gear set geometries, i.e. the machine settings for all HyGEARS supported geometries are calculated and a Summary is created;

3.  Geometries can be imported from Gleason SPA, KIMoS ND and BECAL ND files;

4.  Spiral bevel cutting processes such as Face Milling and Face Hobbing are integral to HyGEARS;

5.  Geometries can be analyzed unloaded and loaded for contact and tooth fillet stresses;

6.  5Axis CnC machine Post-Processing, i.e. the generation of a part program “machine ready”, is integral to HyGEARS;

7.  Part programs are generated in reference to the exact tooth surface definition (rather than an interpolated surface as is the case with the many other CAM softwares);

8.  Part program generation is based on a wide range of user selected cycle features;

9.  Any 5Axis CnC machine architecture can be accommodated; current architectures include “AB”, “AC”, “BA” and “BC”; any controller can be accommodated; current controllers include GCodes, Siemens, Heidenhain and Fanuc;

10.  Part programs can be in Machine coordinates, Work piece coordinates with axis angles, or Work piece coordinates with tool axis vector (Traori, TCPM and TCP);

11. Users can define their own tool box for Face Mill, CoSIMT, End Mill and Ball Mill tools;

12.  Cutting Cycles include Slot by Slot and Flank by Flank, both for tooth flank and fillet; tip chamfering is available;

13.  Animations and single stepping allow the visualization of tool movements and the verification of tool paths and possible interference;

14.  A “Metrics” function gives an estimate of the deviations between the theoretical tooth flank and the “flats” and “peaks” created by the discrete movements of the tool; thus, the # of depth wise and face width steps can be optimized to minimize “flats”, “peaks”and cycle time;

15.  Toe and Heel clearances allow smooth tool entry and exit, and full speed tool plunge;

16.  “Stock” allowance is available for roughing and finishing;

17.  A “Roughing mode” moves the selected tool in the center of the gap to quickly remove as much material as possible;

18.  “Operations”, including all user selections for a given task, may be saved for later re-use;

19.  Closed Loop, also called Corrective Machine Settings, is integral to HyGEARS and allows the seamless manufacture of gears to the required tolerances.

20.  The HyGEARS Closed Loop corrections match (and in some respect are better than) those of Gleason’s GAGE.
