10 Multi Sided Flat Machining ArtCAM 10 Multi-Sided Flat Machining Multisided Machining Wizard To run the multi-sided machining you must have an assembly with at least one component in it Example • Open the saved project pendant-weave.3DP • Select Multi-Sided Machining • Select Edit Settings The form allows you to pick the model type, Flat or a Ring You cannot select both • Select Flat and then Forward The size and resolution of the flat model is shown These can be edited • Change Resolution to 35 and press Forward JewelSmith 10.1 10 Multi Sided Flat Machining • Select Flip-Machine Solid (Male) and then ArtCAM Forward Note: Flip-Machine Mould (Female) is selected when a mould of the model is required to be machined) The form allows you to define the dimensions of the material block that you are using A wireframe representation of the block is shown in the 3D view • Change the thickness to 10, length to 35 and width to 45 • Press Centre in material • Press Forward The previous machining templates for flat machining are displayed A toolpath template is a file, which contains the machining instructions that you want to machine this model with It can be used for similar models The supports are the bridges to stop it falling out while machining All the default machining templates are stored in the ArtCAM files area shown on the desktop In the folder toolpath templates, there are stored templates for the different machines 10.2 JewelSmith 10 Multi Sided Flat Machining ArtCAM The folder ArtCAM files is stored in C:/Documents and Settings/All users/shared documents and is automatically where ArtCAM will search for the template by default, unless you have selected another area Any new toolpath templates you have created should be stored in this area • • • On Flat Template, press Select From ArtCAM Files, select Toolpath Templates/Alcami/Proma PPM/ PPM flip flat select 2mmbn-5conical.tpl and press Open For the output, select Proma PPM Indexer (*.iso ) The indexer, turns the model over to machine the back relief • Change Bridges to 6, width to with a Z thickness of 0.75 and press then Accept ArtCAM calculates the toolpaths using the selected toolpath Templates It will create a copy of the ArtCAM model with the toolpaths in it and any bridges generated in the relief A message appears to confirm the finish of the machining and to indicate where the files are stored • Select OK ArtCAM has created a new Machining folder into which a copy of the ArtCAM model has been saved The postprocessed toolpaths have also been generated and are ready to run on the cnc machine You can look at them in ArtCAM if you want to • From the folder Machining, select ThreeAxisFlat JewelSmith 10.3 10 Multi Sided Flat Machining ArtCAM The model is shown with the bridges modelled in Extra vectors that offset the model have been created automatically • Press F3 The toolpaths are shown above and below the model as the indexer option was chosen it machines both parts of the model The multisided wizard automatically places the base of the model in the middle of the wax for machining • Select the toolpaths tab toolpaths have been created, rough and finish for the front and back Notice the toolpaths which include the name Back are specified with the angle shown in brackets (180) Note Edit Parameters can be used to change the A-Axis index angle before re-calculating the toolpath for very complex jobs By default the front relief is selected, when the model is open 10.4 JewelSmith 10 Multi Sided Flat Machining ArtCAM • Select the toolpath rufFront and press Simulate Toolpath Fast • Select the toolpath finFront and press Simulate Toolpath Fast The model is shown as it would be machined So the finished effect of the tool sizes can be shown The model may need to be changed to make the star weave section bigger, for example If the model is changed the multi sided machining wizard needs to be run again This model can be closed • Select the JewelSmith tab followed by Close Current File icon • Select Save • In Windows, browse for the folder D:\users\training\COURSEWORK\JewelSmithJobs \pendant-weaves\machining\pendant-weaves_1 and select Close Project There are three files in this folder The ArtCAM model, the roughing toolpath threeaxisflatruf.iso and the finishing toolpath threeaxisflatfin.iso The two toolpaths are the ones that are copied over to the PC which runs the CNC machine JewelSmith 10.5 10 Multi Sided Flat Machining 10.6 JewelSmith ArtCAM
