After Grinding NC Grinding of Large Curved Surface

Advanced Materials Research, 2013
Additional power head with common milling machine.Two and a half axis CNC system are used for CNC grinding circular surface curve trajectory. The advantages of this processing method are: We can avoid the influence on processing of lead screw clearance because of changing the parts clamping position,effectively ensure the integrity of the great circle ...

Loose-Abrasive Grinding of Optical Surfaces

Applied Optics, 1972
The aim of the effort reported in this paper was to identify working parameters responsible for the development of a surface shape during lapping with a loose abrasive. A study of the parameters responsible for radius changes during lapping indicates that the complexity of this process can be significantly reduced if proper working parameters are ...

Computer-controlled grinding of optical surfaces

Applied Optics, 1982
A computer is used to regulate the movement of a small pad over the workpiece surface. The computer controls the amount of time any region is worked, which provides an accurate method for correcting surface errors. In addition to polishing operations the computer control process is an important technique for grinding applications.

The Dynamic Behavior of Surface Grinding: Part 2—Some Surface Grinding Tests

Journal of Engineering for Industry, 1971
In Part 1 of “The Dynamic Behavior of Surface Grinding”, a mathematical formulation for surface grinding was developed. The analysis led to several interesting results. As a part of a test program these results were evaluated. The tests were run on an especially equipped Jones-Shipman surface grinder.

Thermal Radiation in Surface Grinding

CIRP Annals, 1982
Summary Experiments on the infrared radiation in surface grinding were conducted using both highly sensitive infrared films and photocells covering most of the interesting spectral range. The “Thermovision” technique applied in tests was coupled with the videotape recording equipment providing a dynamic picture of the events. It was revealed that the

Reciprocating Surface Grinding

1986
Reciprocating surface grinders are used to move the wheel with rectilinear motion relative to the workpiece to generate a plane surface or a profiled surface with zero curvature in the direction of motion. The wheel strokes back and forth over the workpiece, making “conventional” or up-cutting strokes in one direction and “climb”-cutting strokes in the

The Dynamic Behavior of Surface Grinding: Part 1—A Mathematical Treatment of Surface Grinding

Journal of Engineering for Industry, 1971
A mathematical representation for surface grinding is developed. The main feature of the model is that it takes into account the reversing motion of the workpiece, typical to surface grinding. The most general steady state solution is applied to the governing equations to give insight into the dynamic behavior of surface grinding.

Grinding for Microstructural Functional Surface

Advanced Materials Research, 2015
Structural textural surfaces are those surfaces that have designed feature intended to give specific functional performance. In the last few decades, the understanding of structured surface texture, particularly at a micro and nanometre scale, has played a fundamental role in the development of many advanced applications.

A Surface Generation Mechanism of Grinding

Applied Mechanics and Materials, 2016
This paper presents a surface generation mechanism of grinding that captures the microscopic interaction between the abrasive grains and work-surface. The mechanism utilizes both deterministic and stochastic formulations and deals with such realistic constraints as loss/wear and uneven distribution of abrasive grains, roughness of already-ground work ...

Surface Melting in Grinding Operations?

CIRP Annals, 1984
Summary The possibility of surface melting in grinding operations is considered and it is found that this is very unlikely, a finding in keeping with scanning electron micrographic examination of ground surfaces. While thermal pulses of very high magnitude are involved in grinding (sometimes exceeding the equilibrium melting temperature), these are ...
