GETTING STARTE D :

1. Open a new template. ( Predator CNC Editor) Click new (a blank screen will appear). (See fig.1) Left click on the dropdown menu and select Default

Fig-1

2. Type the part program. (See fig.2)

Fig.2

3. Saving the Part program. (See fig.3) File-save as, Save the program as .JOB format (under save as type select “all files (*.*), and under file name “type filename. JOB”) (See fig.4)

Getting started:

1. Open a new template. Select “Lathe_MM” template (See fig.9). Write the part program.

Fig.9

2. Saving the program save the program with .job extension. (As explained in milling)

3. Open “Predator Virtual CNC” (The procedure for opening the program is the same as milling)

4. Defining the job properties (Stock) (See fig.10) a) define the length and diameter of the stock (See fig.10a)

fig.10

fig.10ab) Select the tool and tool type (See Fig.11)

fig.115. Click OK once the job parameters are defined

6. Simulation Note: Same as explained in milling. Few additional features are available in turning (See fig.12)

Generate a part program for the given part.

(Part is shown for example only)

1) Open a

SolidWorks. Using SolidWorks Create the given part. (See

fig.13)

Fig.132) Go to

Options and ADD-IN

CAMWORKS from the list. (See fig.14) Once CAMWorks is added 2 more tabs will appear on (See fig.14a)

Fig.14a

Fig.14

3) Click on the CAMWorks Feature ManagerDefine the Machine, Double-click on the Example mill-mm, select the machine, and select the post processor (See fig.15)Define the stock size Double-click on the Stock manager, and give the blank dimensions (see fig.15a)

(NOTE: The machines shown here may not be the same for customers)

Click on the CAMWorks tab, these icons will be displayed.
