Metal sheet cutting

Cutting-edge technology used in cutting machines.

Costantino is a powerful and flexible CNC that allows you to obtain maximum results with minimum effort for all types of applications.
Costantino CNC is the ideal solution for both new machines and retrofits.
Machines equipped with Costantino CNC are able to meet all Industry 4.0 requirements.

All our experience with these machines:

Waterjet
3- to 5-axis machines for cutting with high-pressure water and abrasive, orienting the jet to create shaped edges.

Specific requirements

  • Constant control of the distance between nozzle and material
  • Very long execution of the part-program which must be interrupted and resumed on the last part of the cutting path
  • Exploitation of cutting times with cutting quality

Plasma & Oxy
3- to 5-axis machines with plasma cutting or oxy-fuel torch, or a combination of both, orienting the cutting direction with the bevel head to create shaped edges.

Specific requirements

  • Constant control of the distance between the torch and the material
  • Cutting progress as constant as possible
  • Applying the appropriate parameters to the cutting technology to obtain the best cutting quality
  • Using high definition sources

Laser
2D cutting machines with CO2 or Fiber laser cutting.

Specific requirements

  • High-speed cutting capability thanks to high power concentration, especially for thin materials
  • Constant control of the distance between the torch and the material
  • Continuous interaction with the supervisor and production management software
  • Applying the appropriate parameters to the cutting technology to obtain the best cutting quality
  • Cut on the fly

Main CNC features

  • PC-based solution: a single hardware containing the CNC together with HMI and CAM with completely separate and independent resources, to increase reliability and reduce costs
  • Look ahead up to 256 blocks, over 15,000 instructions per second
  • Standard ISO6983 syntax for complete definition of parametric machining and nesting programming, simplifying the interface with third-party CAD-CAM
  • Gantry Axes
  • Controlled jerk movements for all axes involved in the movement and separately for the tool tip, to avoid mechanical stress and obtain the best finishing surface
  • High speed machining to chamfer edges while maintaining a defined tolerance, to reduce mechanical vibrations, reduce machining times and improve finishing results
  • Volumetric compensation of positioning inaccuracies due to mechanical asymmetries and machine misalignments
  • Vibration suppression algorithms to prevent workpiece damage, extend machine life, and increase machining quality
  • Coordinates and operating origins for rototranslation and mirror machining
  • High speed machining available on 5-axis interpolation
  • Programming the position and orientation of the tool tip with the Tool Center Point (TCP) applied to chamfer heads
  • Appropriate management of heads with compensation
  • Availability of TCP parameter auto-calibration cycles. The newly obtained parameters can correct the part programs generated by CAM to adapt to reality.
  • Actual feedrate applied on the path, including orientation variations for compensated heads
  • Management of auxiliary functions without having to interrupt movement
  • Trajectory path in front and rear direction (RETRACE)
  • Support for many different digital servo interfaces for controlling servos with position or velocity reference; even pulse-direction servos or stepper motors can be used to their full potential.
  • Feed forward of speed and torque to have a trajectory following error close to 0
  • OPC UA server for connection to MES
  • Remote I/O connected with EtherCAT fieldbus to allow the exchange of thousands of I/O signals
  • IO-Link Interface Gateway
  • Safety integrated with FSoE

HMI

  • Easy OEM HMI integration using reusable user controls or interface customization provided by ISAC
  • High-definition interactive preview that the operator can rotate, pan, or zoom in on. The cut path is color-coded to quickly determine the extent of the work done.

Work aids

  • Consumables life management
  • Resumes processing after an unexpected shutdown from the last executed block or any graphically selected block. Works with repeats and nested macros.
  • Support for work suspension, manual control and maintenance and resumption from on-trajectory or off-trajectory position with automatic trajectory intersection
  • Extremely responsive torch-to-material distance control thanks to a different feedback sensor capable of maintaining a 1/10 mm tolerance even with bevel heads
  • Dynamic TCP to compensate for water jet deflection
  • Cutting process parameter database integrated within the part program. CAM can select parameters based on the material, thickness, and cut quality required for specific sides. The operator can choose a different selection.
  • Parameter Database Editor
  • Jumping movements between shapes to perform the cutting
  • Laser output power for PWM adjustment to current dynamics
  • Start and stop cutting without interrupting movement (Flying Cut).

PLC logic environment

  • Powerful PLC logic shell compliant with IEC61131
  • Extensive application libraries
