High level of automation

Automatic gas box and height control

The oxy-fuel torch is fitted with proportional gas valves which automatically control the gas flow for automatic pre-heating, piercing and cutting. The gas mix is selected based on the thickness and nozzle size from parameters stored in the VACAM operating software. Pressure and gas flow can be controlled from the VACAM control panel so even heavy parts are easy to produce. The flame ignites automatically so no manual proceedings are required to start the cutting flame. It is possible to interrupt the pre-heating process and start cutting immediately by using the control panel. An automatic height console controls the height of the oxy-fuel cutting torch with a capacitive sensor during pre-heating, piercing and cutting.

While the plasma process got more complicated over the years, our in-house developed VACAM operating software counteracted this development by keeping it simple. With VACAM all the parameters are automatically controlled which makes a quality plasma cut very easy for the operator. Parameters like kerf offset, height control, pierce time delay and gas flow are all controlled by VACAM to ensure the best quality cut. All these parameters are automatically selected based on the cutting amperage and the processed material type and thickness. Let the VACAM operating software handle your high quality cuts without any operator intervention to eliminate human errors.

Automatic nesting and NC-programming with SigmaNEST

Voortman offers the advanced nesting engine SigmaNEST for their plate cutting machines for increasing material optimization and cutting efficiency. Advanced nesting algorithms ensure a better part yield and maximize material usage while optimizing the cutting cycle times. A powerful automatic nesting algorithm within SigmaNEST minimizes material scrap. The NC-path for the plate cutting machine is automatically created based on customer preferences. Plates can also be automatically cropped and remnants can be automatically created when desired and stored in the library.

Two important features are:

  • Inventory management and stock control
    The inventory management system within SigmaNEST offers a clear view on the available sheet stock and remnant stock. Remnants, once destined for the scrap yard can now easily be saved for future use. Traceability of remnants is also further increased in SigmaNEST Version 10 because remnants can be marked with material certificate numbers, thicknesses and other preferred settings
  • Accurate cost and time estimation
    During the quote stage of a bid accurate cost and time calculations can be made with SigmaNEST based on the cutting length, drilling length, positioning time and number of pierces. Cutting and drilling time can also be used to streamline the production process and optimize planning.
