Introduction to CAM

CAM:Computer-aided manufacturing (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing of work pieces.

Continued…….

CAM may also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning, management, transportation and storage.

Introduction to EZ CAM

It is a computer software use to control, manage, regulate the manufacturing process.

It is used to operate CNC machines by creating part geometry, working steps and machining parameters and creating G-codes file for that geometry.

CNC machines are•CNC lathe•CNC Milling•CNC wire EDM

Brief History

• Ez-Cam is a suite of products for 3, 4 axis milling, turning, turn/milling and wire EDM.

• Ez-Cam started as one of the very first pc based, easy to use CAD/CAM products in the early 1980's.

• Originally owned by Bridgeport Machines Ltd (Inc) the software has been sold and successfully supported in the UK since this time.

BASIC PROGRAMMING STEPS

• STEP 1:Create Geometry Start by creating part geometry via

commands under the Geometry Menu.

• STEP 2: Define Path Curves Use the “Curves” menu commands like

CHAIN, ARC, LINEAR, etc. to define curves by tracing or chaining existing geometry.

Continued……..

• STEP 3: Create Work Steps and set Machining Parameters Define

Work Steps for each machining operation and apply the parameters as required by type of operation. Visualize the computed path to assure correct operation and proper setting of machining parameters.

• STEP 4: Post G-Code Select the “Postprocessor” related to the

type of control and let the software create the G-Code file.

Example

Creating a program for this part:

• Create part Geometry using line/arc creation and edit commands.

• Define four machining Work steps.

Zig-Zag Machiningremove the outside material

Pocket Machiningcreate inside pockets

Drill center holeDrill bottom left hole

Continued….

• Define paths of the work steps by chaining lines and arcs.

• Verify all command displays toolpaths of the above 4 operations.

• Post command creates the G-Code for the selected control.

Products of EZ-CAM

• EZ-mill express

• EZ-turn Express

• EZ-turn

• EZ-EDM

• EZ-Filter max

• Text CAM

Advantages• Less expensive as compared to other CAM

softwares e.g Mastercam worth 3500$.

• It have G-code generator while some CAM softwares have no G-code generator.

• Mastercam is designed to operate on high performance PC running on XP or Vista platforms, while EZ-CAM can be operated on low specs system.

Disadvantages

• It is not flexible as compared to Mastercam and other CAM softwares. Like Mastercam open virtually any CAD file or use Mastercam's built-in 3D modeling tools.

• EZ-CAM only suit 4-Axis CNC machines while Sprut-CAM works with 5-Axis CNC machines.

Continued…..

• SprutCAM enables to create CLData for the oxygen, plasma, waterjet and laser cutting machines while EZ-CAM only works with CNC lathe,miling and wire EDM.
