Automated Surface Measurement of Engine Components

The automotive sector is comprised of numerous complex engineering processes that must operate to outstanding levels of precision in order for the finished product to meet consumer standards and professional certifications. In recent decades, auto engineering has moved towards pervasive automation with robotic assembly lines. However, analysing the surface composition of mechanical components for contours and variations widely remains a manual process. This blog post will explore the benefits of performing automated surface measurements in the automotive sector in more detail, with a focus on the manufacturing of engine blocks and pistons.

Surface Measurement of Cylinder Heads and Blocks

The surface composition of an engine’s cylinder block is important for ensuring the various components of a reciprocating engine are mechanically cooperative. This involves assessing the alignment of concentric components such as valve guides and seats, camshafts and crank bores, and the cylinder heads.
Such components represent a significant challenge to traditional measuring instrumentation given their variable surface geometries and the importance of prismatic configuration. For example, cylindrical bores must be assessed at a nanometric level to ensure ideal surface concentricity with the cylinder heads for safe internal combustion of fuel.

The Talyrond range of surface measurement instruments is optimized for roundness measurements of engine components of varying surface metrologies, including radial, angled, and straight surface profiles. It can aptly perform fully-automated measurements of numerous engine block surface profiles in a fraction of the manual measurement time with automatic gauge calibration.

Surface Measurement of Piston Pins and Rings

Roundness measurements are also critical for engineering automotive pistons, but the ongoing thermodynamic demands of continuous use require engineers to consider a broader range of factors for piston design. Surface measurements are routinely used to predict the potential for piston distortion as a result of gradual wearing based on various geometric analyses of the component.

Cylindricity, straightness, radial and axial forms, and thickness variation can be quantified on the nanoscale using the Form Talysurf surface measurement analyser. This can accurately characterize the wear characteristics and friction-resistance qualities of piston pins and rings with fully-automated capacities, including part identification programming for the removal of human error.
