According to the numerical control processing characteristics of the multi-holes part,the article analyzes the reasons of the outline error while designing the cut track path and the principle of decreasing the error.

In conclusion, where long tool life, high volume of metal removed, short machining times and high volumetric removal rates were concerned, raster cutter path strategy was the most favourable at all high axial depths of cut employed.

In this paper, the path forming process of grooving cutter in software of Master-CAM is introduced and cutter paths of different kinds of pockets are explained through some examples of complex parts.

Application of MasterCAM Macros in Building Tool-path Template;

Firstly the free surface is analyzed to how to express inSTEP-NC; secondly the messages are abstracted from the STEP-NC program to generatetool-path automatically; finally the way to generation of tool path is validated by thesimulation.

Methods and algorithms are proposed to develop NC cutter tool-path for Loop subdivision surfaces.

The Technology of Tool Path Generation in Any Planar Region;

Generation algorithm of direction parallel tool path based on monotone list;

How to Optimize the Cutting Tool Path in Milling Mold Surface by Using Ball-tool

Analysis of Toolpath Topology in the NC Milling;

After analyzing the feed rate in numerical-controlled machining,this paper introduces the working principles and advantages of the toolpath optimization model of the software,and presents the actual process of optimizing toolpath in VERICUT.

This paper sums up the principles of CNC programming about high-speed mill,the production strategy of toolpath in high-speed mill is analyzed with several typical examples,and the optimum ways of programs in post procession are explained.

from definition of blank from parts outline drawing, establishment of tool route and various processing parameters to simulation of tool route and machining emulation, to final realization of practical and effective NC procedure.
