Task 1 (P6) - Using the Alpha CAM software,

(Drawing 1)

a) Draw the components provided

CNC - level3 Rui Gaspar Simoes June 2015

b)Pick correct tools and add tool paths

In this stage, the aim is to create the geometry component using the geometry menu.

To create the shape of a rectangle billet of material, the rectangle icon is selected. Next step is to create

the geometry for the holes using the circle icon. The edges and the middle geometry are designed using

the line and arc icons.

Next step is to set up the material using the command 3D→Set Material, picking outline of the rectangle and

inserting values to Material Top Z and Material Botton Z.

Material type is selected by default.

Material is chosen using the command Machine→ Select Material and opting out for Aluminium.

After that the tools need to be selected clicking on Machine→ Select tool and selecting the 10mm flat, for instance.

Next, the tools directions are set up using Machine → Tool Directions. In the dialogue box, the following options

are chosen:

Then select the edge of geometry where the machining needs to be started.

After the Rough/Finish is set up using the command Machine→ Rough/Finish and follow the next dialogue boxes:

To add tool paths

In case it is necessary more than one tool path, insert how many milimeters of stock to be left should be

set up, as shown in above image. (Machining → Stock to be Le))

After checking the information, click OK to proceed further. Then select the outside profile to machine

and press finish to continue. The cutter path should appear in red.

To finish this stage, Lead IN/OUT is set up by selecting the command Machine → Tool Lead IN/OUT.

Select Arc in Lead-in and Lead-out.

Then click at the top of the geometry to select the tool path where we would like to beginning the

Rough/Finish.

c)Graphically simulate (to find and correct errors)

To drill the holes, select D4 Drill, for example ,by clicking on Machine → Select tool and then select

the command Machine → Drill/Machine holes → Drill/Tap holes. In the dialogue box enter

information provided below:

Then select the circles to be drilled with the mouse.

In this step, select the command VIEW→3D SIMULATION and run the programme to check for

errors.
