Real-Time Prediction of Workpiece Errors for a CNC Turning Centre, Part 1. Measurement and Identification

Tool probe for measuring dimensional wear and X-coordinate of turning edge

“…To estimate tool wear using an indirect method, the following physical quantities can be measured: -cutting forces [6] and derivative quantities (moment, driving motor current [7], tool elastic strain); -change in surface roughness or geometric dimensions of the workpiece [8]; -vibrations or noise [9]; -stress waves, so-called acoustic emission, AE [10,11]; -cutting temperature.…”

Dynamic characterization of machining systems

“…The theory of the stability lobes highlighted very early the importance of the relationship between the workpiece stiffness or the tool, and the cutting stiffness (the coefficient which links the tool displacement into the material to the cutting pressure, in the vibration direction). The most significant parameter to decrease this ratio is roughly speaking the projected cutting tool edge length in the material, which always impose to the specialists in machining process to naturally reduce the tool axial engagement [25], [34].…”

Resolution in the 3d Modeling of Objects for Additive Manufacturing and Reverse Engineering – Shutter Effect

“…There exists a multitude of examples regarding this change: CAD, CAM, CAE systems, TDT, magnetic resonance, TAC, 3D ultrasound, etc (Bilal et al, 2020;Gonzalo, Sandra & Rodrigo, 2020). 3D scanning is among these techniques, which consists of capturing geometric information of a physical object by means of large capacity data acquisition tools such as laser scanners, optical digitizers, probes, contact arms, coordinate-measuring machines and computerized axial tomography scanners (Babel, Sawicki & Gasiorowski, 2021;Li, 2001). A 3D scanner can be defined as a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance.…”
