Advanced 2D Machining

Introduction

This document details the demonstration from the 2004 User Group to show multiple 2Dmachining strategies and how to get the most out of ArtCAM and ArtCAM Insignia using 2Dmachining strategies.

Matrix Multiplate demonstration 1

In this demonstration the following 2D 2.!D machining strategies will "e co#ered$

Smart Engraving V-Carving Machine Along a Vector Profile cut out using Bridges Matrix Multiplate with Toolpath information

This demonstration shows the Matri% Multiplate tool creating multiple address plates usingmultiple toolpaths. The toolpaths will "e applied to the default num"er plate #ectors whichha#e "een alread& created. The Matri% Multiplate tool will program and calculate an&selected toolpath &ou are using for the Matri% Multiplate and "atch calculate the toolpaths for each created plate.

'or this e%ample the ArtCAM file is set up for us. (e need to appl& toolpaths to the artwor)in order for the toolpath files to cut the parts. These parts will "e cut out of a *.0+ sheet of,a).

The #ector information was designed using ArtCAM and -ector Art. ou will "e appl&ingtoolpaths to the #ectors and sa#ing the applied toolpaths as toolpath templates in thise%ample.

The first toolpath we are going to machine is going to $e the Engravingfeature)

The /ngra#ing toolpath strateg& allows &ou create a toolpath that engra#es the #ector te%t oro" ect that &ou ha#e selected. Multiple tools can "e used for the /ngra#ing tool clearancestrateg&. ou also ha#e the option to select a separate cutting strateg& for each tool listed inthe /ngra#ing toolpath.

The ne%t toolpath for this num"er plate will "e a -9Car#ed toolpath for the -ectors on the leftside of the design. The -9:it Car#ing toolpaths allow designs to "e ;uic)l& machined using a-93haped or :all 8ose tool. The centre of the tool follows the centre of the selected #ectorsand the depth of the cut is determined "& the width of the selected #ectors.
