Overview
This lecture covers the fundamentals of computer-aided manufacturing (CAM), its process phases, required components, and an overview of popular CAM software used in industry.
Introduction to Computer-Aided Manufacturing (CAM)
- CAM uses software and computer-controlled machines to automate manufacturing.
- It converts computer-aided design (CAD) geometry into machine-readable instructions.
- CAM increases productivity, improves product quality, and adapts to market needs.
Key Components of a CAM System
- Software generates tool paths for manufacturing specific parts.
- Machines physically transform raw materials into finished products.
- Post-processing converts tool paths into machine-understandable language.
Phases of Computer-Aided Manufacturing
- 3D modeling: Parts are designed using CAD software, and models are exported for CAM processing.
- Tool path development: Programmers create paths considering tools, cutting rates, and strategies.
- Tool simulation: Simulates tool actions to check for errors or collisions before manufacturing.
- Numerical control program generation: CAM software generates an ISO program for CNC machines.
- Transfer and execution: Program is sent to the CNC machine for execution after adjustments.
Types of CAM and Integrated Software
- Some software integrates both CAD and CAM functions (e.g., CAD/CAM systems like Fusion 360, SolidWorks CAM).
Popular CAM Software
- Mastercam: Enhanced tool paths and integrated CAD tools.
- Fusion 360: Widely used for product development in manufacturing.
- Solid Edge: Known for user-friendliness and complete product development capabilities.
- HSM Works: Reduces cycle time with milling, turning, and multiturn functions.
- SolidWorks CAM: Integrates with SolidWorks CAD for design-phase manufacturing.
- NX CAM: Combines NC programming with manufacturing applications.
- GibbsCAM: Offers rapid parts design tools.
- PowerMill: Features advanced multi-axis milling and reduces development time and cost.
- Cimatron: Integrates tool paths and programming for timely delivery.
- SolidCAM: Unique iMachining technology reduces cycle time by up to 70%.
