This topic contains an introduction to all of the major areas of the CAM system and provides links to all of the machining topics in this help system.
Getting Started Machining
The CAM Tree is where all machining programs start in BobCAD-CAM. The CAM Tree is used to define system settings, including the system defaults and job settings. It is also used to create and edit machining jobs, tools, stock, and features.
The CAM defaults and new jobs are handled using the top folder in the CAM Tree, CAM Defaults. This item is always available in the CAM Tree. The CAM Defaults include the Current Settings, Cutting Conditions, Tool Pattern, Tool Library, Thread Library, Stock Material Library, Adapter Library, and Tool Holder Library. You start with the CAM Defaults to define the system settings as you need them. This includes machine creation and setup, tool data, operation defaults, and stock materials. You can also use CAM Defaults to start a new machining job.
To create a new job or define system defaults for machining:
In the CAM Tree, right-click CAM Defaults.
Select an item from the shortcut menu as explained in CAM Defaults.
All CAM Jobs start with the Machining Job dialog box. You select the Job Type and the machine for the job. You can then start the Stock Wizard, or the Lathe Stock Wizard to begin creating the program. Before you create a job, the CAM Tree only contains the CAM Defaults folder. When you create a CAM job, it is added to the CAM Tree with all the items that you need to start creating the program. The following section shows what items are added to the CAM Tree for each job type. Click the links in the following section to learn all about CAM Jobs.
The following items are added to the CAM Tree when you create a Milling job.

The Default Parameter Templates
When a new CAM Job is created, select a Default Parameter Template from the list available in the Machining Job dialog. You can also change the template in the CAM Tree on a job that has already been created. With the proper template saved to the CAM Tree, every feature and operation which have had custom parameters saved to the template will automatically be loaded with those parameters as their default values. To find out more about the Default Parameter Templates, see The Default Parameter Templates topic.
The machine is an integral part of setting up the software to create
machining programs. The machine controls various settings such as the
post processor and posting parameters for the machine and what type of
programming functionality is available for the current job, such as multiaxis
output. The following topics contain everything you need to know about
machines in Bob
The Tool Library contains the tool data for all Mill and Lathe tools in the system with a Drill category that is shared between the two. Creating your tools in the library can greatly speed up program creation. This makes it easy to add the tools that you need for a job to the Tool Crib, which aids in proper tool selection for feature operations in the CAM Wizards.
Milling, Turning, and Mill Turn
Stock Wizard (Mill, Mill Turn
Setting the stock material for your job defines the feeds and speeds that are used for automatic feedrate calculations in the CAM Wizards.
When you create a CAM feature, the CAM wizard displays to guide you through creating the machining feature. You select the geometry, set the parameters, define the machining strategy, which is the number and order of operations for the feature, and define the individual parameters for each operation. When you finish a machining wizard, the Feature is added to the CAM Tree.
When you finish a wizard, the feature is added to the job in the CAM Tree. The Feature tree handles feature modification, feature creation, feature status, and operation status. This includes posting status, toolpath visibility, toolpath color, and naming. Editing of geometry selection, boundary selection, operation start points, and toolpath calculation is also accomplished using the Feature tree.
Feature, Geometry, and Machining Strategy Reference Guide
Toolpath patterns are used to create repetitive programs from a feature, machine setup, wrapping group, or index system.
The following items are used to create programs for 4 and 5 Axis machining. (View the CAM Wizard topics to learn about the 4 Axis Rotary and Multiaxis features.)
Creating programs for routers, laser, plasma, and waterjet machines follows the same process as milling with some minor differences in the setup process.
Program simulation provides an extensive set of tools for verifying the programs that you create.
All of the following topics explain what you need to know about creating
NC programs (G-Code). The machine is an important part of posting programs
