Strategies for grinding optical free-forms using ball-shaped grinding wheels

In: SPIE Optifab

  • 2009
The demand for non-spherical surfaces and free-forms is steadily growing. Aspherical lenses can reduce the number of necessary lenses in optical systems e.g. used for lithographic devices for production of microprocessors. Parabolic mirrors can be used to focus light beams highly efficiently because of low absorption rates without colour distortion. Combined optical devices with included mechanical functions for assembly reduce necessary production steps. The most common pre-machining method for small numbers of high-precision lenses and mirrors is grinding. Depending on the required shape there are different options for generating surfaces e. g. spheres, parabolic mirrors or combined forms. The most flexible ones are grinding with (i) workpiece and ball-shaped tool rotating and (ii) fixed workpiece with ball-shaped tool rotating. In this manuscript grinding strategies dealing with meander and spiral tool paths are investigated in order to define which strategy works best for machining off-axis parabolic mirrors.

Utilisation of time-variant influence functions in the computer-controlled polishing, vol. 32, pg. 47-54.

In: Precision Engineering

DOI: 10.1016/j.precisioneng.2007.04.005

In the computer controlled polishing, a polishing tool moves in a well-defined manner across the workpiece surface in order to individually remove the surface error-profile. The commonly used technique to calculate the moving of the polishing tool is the dwell time method. Based on a constant (time-invariant) removal characteristic of the polishing tool (influence function) the amount of material to be removed is controlled via the dwell time. The longer the polishing tool is in contact with a particular area of the workpiece, the more material is removed at this position. Mathematical basics to calculate dwell time-profiles are shown, and a new approach considering time-variant influence functions for the computer controlled polishing is introduced. The results point out that time-variant influence functions may contribute to further decrease the process time, and thus to make a computer controlled polishing process more efficient. The reduction of the process time was observed to approximately 35% using a combination of the dwell time method with time-variant influence functions.

Forces acting between polishing tool and workpiece surface in magnetorheological finishing, vol. 7060, pg. 706006 ff..
  • 2008

DOI: 10.1117/12.794196

Magnetorheological finishing is a computer-controlled polishing technique that is used mainly in the field of high-quality optical lens production. The process is based on the use of a magnetorheological polishing fluid that is able, in a reversible manner, to change its viscosity from a liquid state to a solid state under the control of a magnetic field. This outstanding characteristic facilitates rapid control (in milliseconds) of the yield stress, and thus the pressure applied to the workpiece surface to be polished. A three-axis dynamometer was used to measure the forces acting between the magnetorheological fluid and the workpiece surface during determination of the material removal characteristic of the polishing tool (influence function). The results of a testing series using a QED Q22-X MRF polishing machine with a 50 mm wheel assembly show that the normal forces range from about 2 to 20 N. Knowledge of the forces is essential, especially when thin workpieces are to be polished and distortion becomes significant. This paper discusses, and gives examples of, the variation in the parameters experienced during a programme of experiments, and provides examples of the value of this work.

Simulation of a complex optical polishing process using a neural network, vol. 24, pg. 32-37.

In: Robotics and Computer-Integrated Manufacturing

  • 2008

DOI: 10.1016/j.rcim.2006.07.003

Most modern manufacturing processes change their set of parameters during machining in order to work at the optimum state. But in some cases, like computer-controlled polishing, it is not possible to change these parameters during the machining. Then usually a standard set of parameters is chosen which is not adjusted to the specific conditions. To gather the optimum set of parameters anyway simulation of the process prior to manufacturing is a possibility. This research illustrates the successful implementation of a neural network to accomplish such a simulation. The characteristic of this neural network is described along with the decision of the used inputs and outputs. Results are shown and the further usage of the neural network within an automation framework is discussed. The ability to simulate these advanced manufacturing processes is an important contribution to extend automation further and thus increase cost effectiveness.

Near-Infrared Laser Range Finder, using kHz Repetition Rate
  • 2008

DOI: 10.1117/12.800132

The paper deals with laser range finding (LRF) technology for tracking fast-moving objects with kHz laser repetition rates. The LRF is based on time-of-flight measurement, where a short emitting laser pulse is transmitted and its time-of-flight is accurately measured by the electronics with respect to the received impulse from a non-cooperative target. The emitted laser energy is in the near infrared wavelength region. The detector is based on a single-photon detection principle of a silicon Avalanche photodiode, operated in so-called Geiger mode. A solution was devised to utilise single photon detection even at strong daylight conditions. The LRF has been integrated in a robust and compact technology demonstrator, and has successfully ranged to rapidly-moving and accelerating small targets. A detailed mathematical model was developed to predict the ranging performance of the LRF for evolution of application-specific designs. The current technology allows ranging up to a maximum range of 1.5 km with ± 0.5 m accuracy against large stationary targets, as well as tracking of small targets of 75 mm diameter moving up to a range of 300 m with a speed resolution of ± 5 m/s. The LRF device uses a standard serial protocol for device communication and control, and operates at a temperature range from 0 °C - 55 °C.

Lens production enhancement by adoption of artificial influence functions and a knowledge-based system in a magnetorheological finishing process, vol. 6671, pg. 66711J ff..

In: Optical Manufacturing and Testing VII

  • 2007

DOI: 10.1117/12.761356

High quality optical lenses are usually finished by magnetorheological finishing (MRF). In this process an abrasive fluid, with the ability to stiffen in a magnetic field, is used as the polishing tool in a computer-controlled machine tool. Although the machine is automated it is necessary for a skilled operator to set the machine and make judgments with regard to its operation. An investigation has been under way to examine the detailed operation of the MRF process, and the information that is necessary to establish best practice. This has resulted in the incorporation of a knowledge based system (KBS) into the machine control regime, and a methodology for the creation of artificial polishing tool characteristics, the machine influence function. The incorporation of the these elements has been instrumental in the operation of an enhanced MRF machine. This has been subject to extensive test procedures, and it has been demonstrated that the production process may be enhanced significantly and consistently. Batch production time may be significantly reduced, a figure in excess of a 50% reduction was met consistently during prolonged operation. Furthermore the incorporation of the KBS is instrumental in increasing the automation of the MRF process, reducing the levels of manual input necessary to manage machine operation.

Calculation of MRF influence functions, vol. 6671, pg. 66710Y ff..

In: Optical Manufacturing and Testing VII

  • 2007
Magnetorheological finishing (MRF) is a commonly used computer-controlled polishing (CCP) technique for high precision optical surfaces. The process is based on a magnetorheological abrasive fluid, which stiffens in a magnetic field and may be employed as a sub-aperture polishing tool. Dependent upon the surface error-profile of the workpiece and the polishing tool characteristic (influence function) an individual polishing procedure is calculated prior to processing. However, determination of the influence function remains a time consuming and laborious task. A user friendly and easy to use software tool has been developed, which enables rapid computation of MRF influence functions dependent on the MRF specific parameters, such as, magnetic field strength or fluid viscosity. The software supersedes the current cumbersome and time consuming determination procedure and thus results in considerably improved and more economical manufacture. In comparison with the conventional time period of typically 20 minutes to ascertain an influence function, it may now be calculated in a few seconds. An average quality improvement of 57% relating to the peak-valley (PV) value, and approximately 66% relating to the root-mean-square (RMS) of the surface error-profiles was observed during employment of the artificial computed influence functions for polishing.

Coherences between influence function size, polishing quality and process time in the magnetorheological finishing, vol. 6288, pg. 62880Q ff..

Magnetorheological finishing (MRF) is a computer controlled polishing process (CCP), which is commonly used in the field of high quality optical lens production. The process uses the material removal characteristic of the polishing tool (influence function) and the surface error-profile to calculate individual, surface error-profile dependent polishing sequences. At the University of Applied Sciences Deggendorf a testing series with a magnetorheological finishing machine has been performed, and effects of the influence function size and its removal capacity on the polishing quality and the process time have been investigated. The result of the research shows that the influence function size has a major effect on the process time, whereas the polishing quality is nearly independent of the influence function size. During the testing series the process time was significantly reduced using an appropriate influence function size. The process time decreased about 9% relating to the original influence function.

A new approach to predict computer-controlled polishing results, vol. 5869, pg. 94-102.

A novel approach to handle and quantify a computer controlled polishing process will be introduced. This approach will be compared to real data. This comparison indicates the correctness of this approach. Based on it a formula has been developed to predict the results of a computer controlled polishing process. The formula will be used to predict real polishing processes and the results will be compared to the real results. The limits when using this formula will be shown along with suggestions when the formula would be useful. This rough prediction of the computer controlled polishing results may be used to enhance the automation of a computer controlled polishing process. Also a way to improve the formula itself will be introduced. It is the opinion of the author that by further stabilizing of the whole computer controlled polishing process the whole system becomes more robust, the prediction more accurate and the whole system improves in reliability and the results become better.

Satellite Laser Ranging Portable Calibration Standard Missions 1997-2002, vol. 5, pg. 14013.

In: Geophysical Research Abstracts

  • 2003
The recent requirement of the Satellite Laser Ranging SLR technique is to reach the accuracy of a millimeter. This requires keeping all the system biases on the sub millimeter level. The Portable Calibration Standard is a global reference for Satellite Laser Ranging systems biases identification and evaluation. It consists of the Pico Event Timer P-PET, meteorological station, epoch and frequency time base, set of reference retroreflectors and the control / data processing software package. The P-PET is compact, stable and easy to re-allocate within days. Its properties are appropriate for calibration standard purposes: the timing resolution is 1.2 psec, 2.5 psec per channel timing jitter, the temporal stability is less than 0.5 psec per hour and below 0.5 psec per Kelvin. The key feature of the timing system is its long term stability: no adjustments and settings are needed. Before we could start the global SLR network calibration, we had to succeed with the calibration missions at several SLR stations in Austria, Germany, Switzerland, United Kingdom, China and Chile. This enabled us to understand the feasibility of using the Pico Event Timer P-PET. Summarizing the results: the ranging precision to ground target is 1-3 millimeters, to satellites is 3-7 millimeters rms, the Calibration Standard demonstrated its capability to identify the SLR system range and time biases at the one-millimeter level. These results might serve as a background to the proposed 6th Framework programme EU Integrated Project EUROLAS CALNet.
