VERO UK TRAINING MATERIAL 2D CAM Training VISI Machining – 2D CAM Vcamtech Co., Ltd 1 VISI Machining – 2D CAM INTRODUCTION During this exercise, it is assumed that the user has a basic knowledge of the VISI-Series software. OBJECTIVE This tutorial has been written to give a user a step by step guide on how to use the new VISI 16.0 CAM interface. This tutorial will also give an in depth knowledge on using the 2D CAM and all of its features, from creating a simple toolpath and using the different geometry methods, too editing the toolpaths and geometry. Things that will be covered in this training document: • Creating Manual Features • Creating Toolpaths – Pocketing, Milling, Face milling • Creating a Drilling operation • Creating 2.5D Toolpath • Editing Model Geometry • Editing Tools • Creating Tools • Using Toolholders Vcamtech Co., Ltd 2 VISI Machining – 2D CAM Manual Features From the menu select file > Open The file that were about to use is installed by default and can be used at any time. Navigate to the following location and open the file - Compass Technology.wkf C:\Visi16\Workf\Sample\Cam Vcamtech Co., Ltd 3 VISI Machining – 2D CAM The file itself is made of solid models. In version 16.0 of Visi It is now possible to directly machine in 2D from a 3D model. From the menu select Machining > CAM Navigator Inside of the CAM Navigator it is possible to define all of the Machining that is required. This ranges from 2D all the way through to 5 axis, all of which uses this main interface. Inside of the CAM Navigator you will see there are two pages, Feature and Operations. The Features page is used to control all of the Model geometry that is being machined e.g. Pockets, Profiles, Holes, Piece Material, Stock Model, Obstacles. The Operations page is where all of the toolpath data is stored. Inside of this window it is possible to edit the machine tool that is being used and which tool crib is being used, modify the toolpath parameters e.g. Step over and step down, Tool that is being used, post processor that is being used. The first thing that we will do is to define a pocket to be machined out. From inside the Feature page right hand click on the Model Manager option and select Add manual Feature Vcamtech Co., Ltd 4 A manual feature can be a combination of things, face, point, circle, arc, profile and set of points. This will allow you to pick any of these items and create a blind hole, through hole, closed pocket, open pocket and a boss VISI Machining – 2D CAM With this option selected the system will ask you to pick a face or element. Ensure the face selection icon is active and pick on the green face as shown bellow Once this face has been selected the system will open a new dialog box displaying the information about what has been picked. Inside of this dialog box it is possible to add and remove geometry that has been selected or miss-selected. Vcamtech Co., Ltd 5 Select this Face VISI Machining – 2D CAM Select Ok to the dialog box. With the model selection now confirmed the system will now open the Feature parameters dialog box. Inside of this dialog box it is possible to define what kind of manual feature you wish to create by changing the feature subtype drop down box. Vcamtech Co., Ltd 6 Selecting this icon will allow you to add more geometry to the selection. This icon will allow you to pick an item from the selection tree and remove this from the selection. VISI Machining – 2D CAM Please note that this list can vary in length depending on the shape of the feature that has been picked e.g. Cylindrical Hole or Point = Inside of this dialog box it is also possible to define a variety of parameters for the feature that has been chosen e.g. diameter, tip angle, thread diameter. These parameters are feature sensitive, so if that particular parameter does not have an affect on that feature it will be greyed out. In this dialog box it is also possible to directly interact with the feature Manager if a cylindrical hole or Point has been selected by picking on the “Feature attribute icon” this will allow you to assign a feature such as tapping, counter boring, drilling to a hole. Ensure the feature subtype is set to pocket and the height is 20 and select OK to the dialog box. Vcamtech Co., Ltd 7 VISI Machining – 2D CAM Once the Feature parameters have been confirmed you will now see a feature has been added to the Model Manager tree With the feature now added it is possible to add our first toolpath. N.B. All parameters for features, toolpaths, models etc are all controlled from the right hand mouse menu. Right hand click on the newly created feature and select “Add Operation”.` The system will now open the Operations dialog box. Vcamtech Co., Ltd 8 VISI Machining – 2D CAM Inside of this dialog box it is possible to select the toolpaths that is required. The system is will filter out any operations that cannot be applied on the feature that has been chosen. 1. Search – this command will allow you to type in the name of the toolpath you are looking for in the text box provided. 2. Clear Search – this will remove any search that has been applied 3. Add to favourites – this will allow you to select a toolpath and copy it into the favourite’s folder. This will allow you to develop a list of frequently used commands. 4. Style – this changes the layout style of the dialog box 5. Delete – this command will allow you to remove a toolpath from the favourites section. Select the pocket operation and select ok With the toolpath now defined, the next step is to select which tool we wish to use from the tool crib. 1. Add tool from DB – This will allow you to select a tool from the VISI Tools database 2. Add tool manually– This option will allow you to create a tool manually from scratch 3. Edit Record – This option will allow you to edit the parameters of a tool 4. Duplicate Tool – This option will allow you to make a copy of a previously defined tool 5. Change Tool position – This option will allow you to edit the tool position in the crib. 6. Edit tool holder – This option will allow you to add or edit a tool holder 7. Delete Record – This option will allow you to delete a tool from the crib. Select the 10mm Endmill from the tool crib and press OK. Vcamtech Co., Ltd 9 1. 2. 3. 4. 5. 6. 7. Pocketing 1. 2. 3. 4. 5.
