Dontyne Systems (Booth #213) has released a second update to the Gear Production Suite (GPS) in 2025 to reflect the volume of recent technical additions. Originally developed in 2008, GPS integrates gear design, machining simulation, and inspection data into a single environment to identify and mitigate manufacturing issues at the design stage.
The software’s Loaded Tooth Contact Analysis functionality has been extended to hypoid gear geometry. Additional design and analysis features have been introduced to support non-standard gear forms requested by users in specific application domains.
Manufacturing simulation capabilities have continued to expand. Modules for plunge shaving and internal profile grinding have been added alongside existing processes such as hobbing, shaping, external shaving, and form grinding. The skiving simulation supports both internal and external cylindrical gears and is used to optimize tool design, machine settings, and cutting conditions over the life of the tool, including post-sharpening states. The module has been adapted for non-involute profiles and is compatible with both dedicated machines and 5-axis CNC platforms.
The honing simulation now includes analysis of contact line distribution to evaluate force balance during generation. It can also incorporate data from upstream roughing processes—such as hobbing or skiving—to improve calculation of stock allowance and breakout location at the tooth root.
The GPS CAM module has been extended to simulate the production of straight and spiral bevel gears using fixed tools on 5-axis CNC machines. This workflow is suited to batch production where machine utilization and toolpath control are critical. Dontyne continues to support prototyping and gear testing, providing output in the form of CAD models, GPS project files, and inspection reports.
The Inspection Centre Module interfaces with coordinate measuring machines (CMM) and dedicated gear inspection systems, maintaining consistent surface definitions between design and measurement. Measurement data may be imported into GPS for closed-loop feedback in load distribution analysis or for compensating deviations from machining processes.
A standalone inspection package, the Dontyne On Machine Measuring System (DOMMS), has been introduced to perform gear geometry evaluation directly on machine platforms. DOMMS is compatible with multiple hardware configurations and produces measurement data that integrates with GPS analysis modules.
