10.1  CAM Programming
CAM Mode
CAM Mode is different from the standard CNC programming method 
of part programming. With CAM programming, you create part 
programs with the help of geometry tool buttons. These buttons 
prompt you for necessary information. CAM Programming utilizes a 
graphical interface and features that eliminate the need for CNC 
programming and complicated calculations.
To use CAM programming, you must know the XYZ (Cartesian) 
coordinate system, the polar coordinate system, and machining 
sequences. Refer to chapter "2.1 Fundamentals of Positioning on 
page 26”. 
You must make a machining plan, decide which type of 
tools to use and when to use those tools in the program.
CAM programming is used to generate tool paths from “Shapes.” 
These Shapes are generated from geometry created with the CAM 
geometry tools, importing geometry in a DXF file or a combination 
of creating and importing.
To create the geometric elements required for a part program, such 
as: points, lines and circles, select the appropriate Geometry Tools 
button. Next select on the appropriate sub-tool button. The CAM 
software prompts you to enter the required information to create 
the geometry. These entries combined with selecting shapes and 
creating tool paths enable the system to perform the desired 
machine sequences. As you program points, lines and circles, they 
are displayed on the Graphics screen. The resulting tool path is also 
shown in the graphics screen for tool path verification.
CAM mode features a powerful tool table which can be used to 
calculate feeds and speeds used in the program.
To utilize this feature tools must be set up in the CAM tool table. 
Feeds and speeds can also be manually entered and calculated 
values overridden.
CAM Mode enables you to generate complete part programs. CAM 
generated programs are based on canned cycles which makes the 
program easier to edit outside of CAM if needed.
