Abstract
Parametric CAD/CAM software for turbomachinery components
Documentation version: 5.12
Subject matter and technical features
This document describes graphics-oriented, parameterized CAD/CAM software for modeling and efficient machining of turbine blades, blisks/IBRs, and blings using 5-axis machining. The software offers the following technical functions:
- Interactive user interface with parametric definition of machining operations on free-form surfaces.
- Modeling of air blades, blisks, and blings, including special function modules for spline fitting, segmentation, edge fitting, and integration of IGES and Parasolid data.
- Strategy modules for various machining scenarios: adaptive measuring programs for surfaces, basic and advanced machining strategies (roughing, surface machining, pocket milling), special strategies for blades, blisks, and blings, kinematic analyses, and process automation.
- Automated post-processing and collision control, especially for complex geometries in turbomachinery manufacturing.
- Use of specialized tools (ball/barrel cutters, toroidal tools) and simulations of tool paths for various machine post-processors.
Functionality and modules:
- Complete management of tools, machines, post-processors, and machining operations, including approach/departure movements and motion-optimized toolpath generation.
- Import and processing of CAD geometries (IGES, Parasolid), generation and optimization of airfoil geometries through curve and surface operations.
- Special modules for cutting force control, dynamic stability analysis, and automated communication with CNC controls to enable adaptive geometry corrections and air blade-based manufacturing.
- Additional strategy packages (Adaptive, Blade Finishing, Slot, Edge Breaking, Solid Roughing, etc.) allow for customer-specific extensions and deep process optimization.
Application variants and configuration options:
- Licensed modularization for basic functions, strategy modules, and optional extensions (postprocessors, reporting, cutting force analysis, Vericut model, automation, etc.).
- Application on Windows PCs with special hardware (recommended NVIDIA graphics, ≥8GB RAM, 4+ processor cores) and variable, machine-related license structure.
- Flexible training and support, including maintenance options, updates, and specific training measures for customers.
