“…Then the adapted method is to stop reading the data of the NML channel and report the collision information for correction of the NC program. If there is any intersection between the tool header and the workpiece, the adapted method is to make intersection calculation, update TDGR model, display on the computer screen and read next data [14]. In this paper, a new geometry modeling method of TDGR is proposed.…”

This paper researches on the machining simulation of the multi-axis numerical control (NC) system, and proposes a new algorithm of intersection calculation and collision detection based on Three Dimensions Grid Representation (TDGR) . The suggested algorithm is applied for the simulation system of the LT-NC310 system, whose data communications between simulation and task controller are completed by Neutral Message Language (NML) mechanism. The test has proved that the simulation system can accurately display the machining process with fast computation and less memory consumption.

In the geometric simulation of multi-axis milling, a dexel representation solid model is frequently used. In this modeling method, the object shape is defined as a collection of vertical segments (dexels) based on a two-dimensional regular square grid in the XY plane. In this paper, the authors propose the quad pillars algorithm and its enhanced version named the delta pillars algorithm for converting a dexel model to an equivalent polyhedral stereolithography (STL) model. These algorithms define a series of vertical pillar shapes for each square cell of the grid to represent the object shape as a bundle of pillars. The final polyhedral model is obtained by performing a simplified Boolean union operation of the pillar shapes. Unlike prior methods, the proposed algorithms are simple and fast and are guaranteed to generate a watertight polyhedral model without holes, gaps, or T-junctions. An experimental system is implemented and conversion tests are performed. The system converted a dexel model based on a high-resolution grid to a polyhedral model in a practical amount of time.
