ALPHACAM TRAINING MANUAL PDF

Receive an in-depth technical explanation of 3D Polylines including how to create them, how to extract them from external cad input, and how to edit and machine the 3D Polylines. We will also discuss some of the more popular Edit Machining options available to you like adjusting rapids, editing feed rates and applying support tags. What others are saying about our AMF course: "Nice refresher and learned some useful info They are very beneficial and convenient. This is some of what I was looking for. I look forward to future courses.

The HELP file is very comprehensive. When you have finished the tutorial, please take time to have a look at it.

This AlphaCAM tutorial has been designed to give you a flavour of how AlphaCAM works, how interactive it is, how easy it is to learn and how easy it is to use. We assume that you are familiar with the concepts involved in CNC programming and have a reasonable understanding of your computer and the Windows operating system.

AlphaCAM has been developed as a true bit Windows 95 or NT application, so if you use other Windows programs you will be familiar with features such as floating button bars, tabbed dialog boxes, etc.

AlphaCAM systems are available for all machining disciplines. Each one is specifically designed for the machine type, but the look and feel of all the systems is standard. The tutorial describes the construction and machining of the geometry for the following drawing. This will take you into the graphical portion of the system. Your screen will look similar to the one below. Page 1. During this tutorial, we tell you where to find commands on the pull-down menus.

If there is a button for the command, this will also be shown. Take the trouble to locate the buttons on your screen. You can speed up your work by avoiding having to pull down menus and side menus to click on commands, when one click on a button will suffice. To see what command a button performs, place the screen pointer over the button for a couple of seconds, and a prompt will appear beside the pointer.

Page 2. This drawing is the part on which you will work in this tutorial. It was drawn, dimensioned and printed using AlphaCAM. By the end of the tutorial, you will have created the NC program for the drawing. AlphaCAM provides various ways of creating part geometry. Conventional CAD style geometry creation , whereby individual geometric features are created and then trimmed in order to create geometric contours. Toolpaths are then applied to the geometric contours, from which the NC program is produced;.

Page 3. This can turn some designs into geometric contours much faster than with any conventional CAD system. Instead, you say how the tool should move from one element to the next. Each change in direction is called a Turn. However, CAD-style geometry creation using Line, Arc and Circle commands is sometimes appropriate for simple shapes, and all the conventional CAD commands are included, plus Special Geometries, which automatically produce standard geometric shapes.

Page 4. For this demonstration tutorial it is not a requirement to create the geometric surfaces. These have already been created in the sample drawing provided with the system. Select File Open. The Open dialog box is displayed. Click here. If the drawing is not on your system it can be downloaded from the training page of the web site. Select the. Click [ on. A warning box is displayed, as some layers have been turned off to avoid confusion. Click [ on K K K K and the drawing is displayed.

Page 5. With 3D machining, components may be cut in a variety of ways in order to achieve the results required. The following is a sample list of items that affect the method of machining -. The nature of the component being cut. Component material free cutting, brittle, work hardened. Cutting tool type and material. Method of work holding. The coolant delivery.

The surface finish required. The surface finish achievable. The cutting time cost of machining compared with cost of other finishing processes. The machine tool rigidity and repeatable accuracy. The part accuracy required tolerance achievable. Some parts require all the surfaces to be machined together, as in this example. Others will require the individual surfaces to be machined separately. Page 6. For the demonstration example, the cutting is produced in 3 operations, machining all surfaces.

The tooling and number of cuts will obviously depend on the nature of the material being cut, its usage and any work holding. The function of this tutorial is to show how different cutting strategies are applied to 3D surfaces. For some jobs, the machining will require 2D and 3D strategies to be applied prior to the 3D machining toolpaths.

Operation 1 Z Contour Roughing. The Z Contour roughing operation is used to remove the bulk of the material quickly. Operation 2 Rough Machine Surface. The rough machine surface operation is used to remove the excess material left by the Z contour roughing and leave a uniform surface for the finishing operation.

Operation 3 Finish Machine Surface. The finish machining operation is used to produce the component to the required finish and size. End cutting roughing tool. Ball End roughing tool. Ball End finishing tool. The time taken to produce your work will depend largely on the specification of the system on which you are running AlphaCAM.

The version of Windows you are using will also have an effect. Page 7. AlphaCAM displays a dialog box showing the available post processors.

Select the post processor for your machine. The post processor determines the format of the output code. AlphaCAM displays a warning if values entered exceed the maximums set in the post processor.

Feeds and speeds is determined automatically based on the material and tools used. Select a suitable material and click [ on K K K K. This displays all the folders within the metric tool library. Note: selecting the title box of each column modifies the tool library order.

For example to sort the tool library into diameter and type order, click [ on the Diameter title and then on the Type title. Alternatively, you may select a suitable tool from your own library. Whichever you choose, click on displayed on your screen. Page 8.
