Abstract: The cloud computing can allocate computer resources according to customers different demand dynamic status, which has improved the calculation efficiency, and saved the cost of hardware. This paper establishes the 3D mathematical model of data programming tool radius compensation system, and gets the tool radius compensation control equation according to the interpolation function. It designs the tool radius compensation discrimination system with the combination of UG software. In order to verify the validity and reliability of the system, the paper takes the processing process of leaf as an example to design the tool radius compensation algorithm, and the compensation deviation has been made numerical simulation, which has obtained error compensation curve and tool radius compensation parameter table. It can obtain reasonable tool compensation cutter and cycle according to the input of tool parameters, which provides technical support for the research of numerical control (NC) machining technology.

Abstract: This paper presents a 3D tool radius compensation for five- axis peripheral milling in CNC systems. Using a generalized kinematics model of five- axis machines and uniform algorithm, it is possible to calculate the complete analytical equations for the tool orientation relative to part. The tool orientation relative to part selecting as Z-axis is used to establish compensation coordinate system. The points in the machine coordinate system are converted to the compensation coordinate system. The compensation points in the compensation coordinate system using these points can be calculated. This computation procedure is similar to the calculation of cutter compensation C. The compensation points in machine coordinate system can be obtained by converting the compensation points in the compensation coordinate system to machine coordinate system. The presented methodology was used in the CNC system, which makes the CNC system more efficiently and systematically

Abstract: Microlens arrays are widely used as critical components in a large number of photonics and telecommunication products. The increasing demand for high-tech products provides an expanding room for the development of the micro-fabrication technology. This study presents a tool compensation for correcting the form error of fabricated microlenses in ultra-precision machining with fast-tool-servo (FTS) system. After presentation of optimal cutting conditions deduced on the basis of cutting experiments of microlens arrays, a tool radius compensation method will be proposed and evaluated in this paper. This methodology makes use of form measurement data from a Form Talysurf system to modify the C program employed in the software of ultra-precision machining FTS system – SOP. The form error was successfully reduced after implementation of tool compensation.
