ECam

ECam is a programming system for CNC lathes and machining centers. It combines features of CAD/CAM systems with typical conversational programming functions. No prior experience with CAD/CAM systems is required to use this program. ECam allows you to create designs and simulate the cutting process with a computer-programmable lathe. The software generates operations for cutting, drilling, facing, knurling, or grinding parts. Each stage of the process is configured in a graphical environment where elements are visualized and modified in 3D.

• 2D/3D Geometric Design. Comprehensive tools for creating part geometry from scratch or importing existing files. The module includes vector drawing functions, contour editing, and object transformation. Users define the profiles, contours, and surfaces required for manufacturing.
• Conversational Programming. A question-and-answer-based interface that guides the operator during the creation of CNC programs. The system presents sequential options based on the selected operation type. This method reduces programming errors and speeds up the setup process.
• Automatic Toolpath Generation. Algorithms that calculate optimal tool paths based on the defined geometry. The system considers material parameters, tool type, and machining operation. The paths include approach, cutting, and retract movements.
• CNC Tool Library. A database storing technical characteristics of inserts, chucks, and special tools. Each record contains dimensions, materials, angles, and recommended cutting speeds. Users can update the library with custom tools.
• Material Removal Simulation. Dynamic visualization of the material removal process during machining. It shows the evolution of the part from the initial block to the final geometry. Detects collisions between machine components, tool, and fixtures.
• Collision Verification. A system that analyzes interference between all elements of the machining environment. It evaluates axis movements, turret positions, and spindle head displacements. It presents visual warnings and stops the simulation upon potential impacts.
• G-Code Generation. Translation of programmed operations into specific machine language for CNC control. It produces commands understandable by Fanuc, Siemens, Heidenhain controls, and other systems. Allows customization of output formats according to post-processor requirements.
• Cycle Time Calculation. Accurate estimation of the total machining process duration. It considers feed rates, rapid traverse speeds, and tool change times. Provides data for production optimization and costing.
• Material Manager. A catalog containing physical and mechanical properties of metals, plastics, and composites. It stores information on hardness, resistance, and behavior during machining. Cutting parameters are automatically adjusted according to the selected material.
• Multi-Face Turning Module. Programming of operations on multiple faces of a part without re-clamping. Coordinates movements between the tailstock, steady rest, and main spindle. Synchronizes C and Y axes for complete machining in a single setup.
• Threading Operations. Generation of internal and external threads with metric, Whitworth, or trapezoidal profiles. Calculates pitches, depths, and number of passes according to the selected standard. Includes fixed cycles for tapping or threading with single-point or multi-point tools.
• Deep Hole Drilling Cycles. Programming of holes with a high length-to-diameter ratio using peck or dwell cycles. Controls chip evacuation, lubrication, and dwell times. Adjusts parameters for drilling in difficult-to-machine materials.
• Roughing and Finishing Machining. Differentiated strategies for rapid material removal and achieving controlled surface roughness. Roughing with high material removal rates while maintaining mechanical stability. Finishing with paths that optimize tool-part contact.
• Tool Wear Compensation. A system that adjusts tool paths based on the actual measured wear of inserts. It incorporates correction values from probes or post-process measurement. Maintains geometric dimensions within specified tolerances.
• DNC Communication. Bidirectional transfer of programs between computer and CNC control via serial or Ethernet protocols. Drip-feeding for programs that exceed the CNC's memory. Logs messages and alarms from the control during execution.

ECam was developed by ElettroSystem, an Italian company specialized in solutions for industrial automation. The project began in 1996 as an offline programming tool for CNC lathes. The first commercial version was released in 1998 with basic conversational programming capabilities. The software is primarily written in C++ with Qt graphical interface components. The geometric calculation modules use internally developed computational geometry libraries. The development team includes mechanical engineers, system programmers, and manufacturing process specialists.
