Why NESPERT?

All CAM systems NESPERT use their own/proprietary computing core for true shape nesting, have a common work methodology and a unified user interface.

The nesting in NESPERT is true shape, tight, optimised, step-by-step, with on-line control against overlapping, with arbitrary sequence of automatic nesting and interactive functions.

The CAM systems NESPERT have highly developed functionality for processing technology and NC programming. The Processing technology is always created with on-line control against overlapping.

The nesting algorithms in NESPERT have no limitation of accuracy and dimensions. Even 15 years ago we were nesting with or without technology on plates the size of ½ football field and was programming processing with an accuracy of 0.001mm.

The system is set for a specific machine model using an Universal Postprocessor and relevant Technological Datasets. For special programming cases, an external postprocessor is used - a Python program.

The result of designing with NESPERT CAM is a Nesting Layout, containing information about a plate with material and thickness, a list of parts with quantities, an NC program, technological and production documents.

The NC programs, technological and production documents and all variants of pricing and offers are generated from a NESPERT CAM project.

In the past 25 years of NESPERT CAM system development, there has never been a failure to set up and run NESPERT to program a CNC machine for thermal or jet cutting.

The implementation of NESPERT CAM leads to improved time utilisation.

During a work shift, speeding up the work by program and reducing downtime, increases the productivity of the CNC machine.

The machining time (processing time as per NC program) can be reduced using:

• Cutting with common cuts - to reduce the length of the cutting moves,
• chain cutting - to reduce the number of pierce points and the time for lifting the cutting head away from the plate and positioning it for piercing,
• collision avoidance - to avoid collisions between the cutting or laser head and the plate or raised parts.

The preparation time for working by NC program includes:

• Time for placing the plate on the machine table,
• time for loading the NC program in the CNC controller,
• time for setting the cutting regimes in the CNC controller and/or in the energy sorce,

For some thermal cutting machines the preparation time can also include:

• Time for setting the loaction/orientation of the plate,
• time for parts' geometry import,
• time for creating an NC program,
• time for program test run.

When the operator panel of the CNC controller has the option to import geometry and figure cutting, the operator programs the machine from the console, but at the expense of downtime. This downtime can be avoided by off_line nesting and programming at a separate workstation with NESPERT CAM and NESPERT NCV.

The finalizing time for working by program includes:

• Time for removing and arranging the cut parts,
• time for removing the scrap skeleton,
• slag cleaning time.

The finalizing time for removing parts from the machine table after processing can be reduced considerably by using cutting with bridges, gaps, pseudo-bridges and cutting the scrap skeleton.

Reducing the preparation and finalizing times and increasing program execution time is the way to increase productivity using nesting CAM systems.

The errors in production with true shape nesting are a significant reason for loss of money and reputation of a company.

The frequency of these errors increases proportionally to the increase of production load, and the consequences are:

• offers with no profit or at a loss,
• low processing quality and high waste rate of parts,
• increase in metal consumption,
• missed deadlines,
• damage of machinery and equipment.

To decrease or even exclude the influence of the errors NESPERT CAM provides in the standard license bundle advanced functions for automatic and interactive nesting and for processing technology management, and also:

• NESPERT Office - CAPP system for technological preparation of true shape nesting,
• Library NESPERT rSales – for express pricing and offering in a project and in an order,
• Library NESPERT rAMT – for cutting technology with parallel torches,
• NESPERT NCV – stand-alone system for verification of NC programs.

Ensuring consistently high quality of design and offering results, the system also ensures the corresponding consistently high quality of the manufactured parts.

The CAM systems NESPERT:

• manage the offering and the nesting order preparation,
• manage sheet metals stock,
• perform true shape nesting and NC programming of CNC machines for thermal cutting,
• dispatch, control and report the nesting production.

Using the CAM systems NESPERT the user can achieve full traceability of the parts by certificate and Heat № of the used plates.
