Quality Improvement of a Grinding Operation Using Process Capability Studies

Quality is a state of a finished product, being free from defects, deficiencies and significant variations. This measure of an excellence can be brought about by the strict and consistent adherence to measureable and verifiable standards to achieve uniformity of output that satisfies specific customer or user requirements. This paper gives a proposed methodology for to increase the quality of a...

Surface hardness improvement in high efficiency deep grinding process by optimization of operating parameters

The grinding is one of the most important methods that directly affects tolerances in dimensions, quality and finished surface of products. One of the major problems in the material removal processes specially grinding is the heat generation during the process and the residual tensile stress in the surfaces of product. Therefore, optimization of High Efficiency Deep Grinding (HEDG) process is t...

Impedance Control of Robots Using Voltage Control Strategy Revisited

In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...

In-process force monitoring for precision grinding semiconductor silicon wafers

Forces generated during precision wafer grinding are small and present challenges for accurate and reliable process monitoring. In this work, these challenges are met by incorporating noncontact displacement sensors into an aerostatic spindle that is calibrated to measure grinding forces from the relative motion between the spindle rotor and stator. This arrangement allows the calculation of gr...

Forging Process Control by Additional Rocket Force

Technological processes such as forging, die forging, and pile driving are realized as a result of a collision between two bodies. After the impact the bodies’ energy transforms to plastic or elastic deformations of the colliding bodies. This paper studies both theoretically and experimentally the influence of impact parameters such as forces, accelerations, velocities, time and energy on defor...
