Traditionally, manufacturers have ensured accuracy of parts by calibrating just the linear motion of their machine tools. The problem: When making three-dimensional parts, knowing a machine’s one-dimensional accuracy ignores squareness, straightness, angular, and non-rigid body errors, which are the largest contributors to positioning inaccuracies. This presentation will detail the machine tool design and construction characteristics required to ensure optimum volumetric accuracy, and the instruments used to verify and measure volumetric accuracy.
- What is volumetric accuracy and why it is important to aerospace parts manufacturers and the machine tool construction and design methods that promote volumetric accuracy
- Ask the right questions pertaining to accuracy specifications when comparing machine tools
- Realize the relationship between the volumetric accuracy of a machine tool and a company’s profitability
