Development of a new CNC grinding machine for 3+2-axis grinding of the profile rotary milling cutter

Five-axes grinding with CNC rotary tables

Dama Technologies specializes in the manufacture of machines which are able to process glass, ceramics and other hard-brittle materials at high precision. One of the highlights of the program is the five-axis, USG 500 ultrasound-assisted grinder, in which a hightorque Lehmann EA 520.L rotary table functions as a swiveling machine table. It contains a high-speed torque axis, which was manufactur...

A practical approach for simulation and manufacturing of a ball-end mill using a 5-axis CNC grinding machine

This paper presents a detailed manufacturing model that can be used for grinding a ball-end mill using 5-axis CNC (computer numerical controlled) grinding machine. The profile of the helical groove can be calculated exactly using the given wheel profile and relative movements between the workpiece and the grinding wheel. The proposed model is related to some analytical, differential geometry an...

Development of Robotic System for 3D Profile Grinding and Polishing

a new method for tool-path generation and adaptive interpolation of a three-axis cnc milling machine

in this paper we present a new method for tool-path generation and adaptive interpolation for a three-axis cnc milling machine. this method satisfied the force and / or the error conditions by using a variable-direction variable-feedrate strategy based on maximum feedrate map. the proposed adaptive interpolator modifies the cutting path and the moving direction according to the actual instantan...

Development of a Knowledge Warehouse for Grinding

Successful of grinding in practice is highly depending on the level of expertise of the machinist and engineer. Knowledge Management might offer a strategy to keep the valuable knowledge. The main objective of Knowledge Management (KM) is to manage knowledge process, the knowledge itself could not be managed, what can be managed is the knowledge gathering, storing and organizing, retrieving, an...
