Why NESPERT?

NESPERT is a scalable CAM/MES system for of nesting production preparation with CNC machines for thermal cutting

NESPERT®

NESPERT is the new registered European trademark for the CAM and MES systems for professional true shape nesting developed by Vintech for 30 years.

The name NESPERT has its roots in terms, related with the true shape nesting software – NESting from true shape nesting of sheet parts or NES, from Nesting Execution System - MES system for true shape nesting production, and more than 45 years exPERT experience in the production with CNC machines, 30 of which – in the area of true shape nesting.

NESPERT is the successor of the trademarks of the CAM and MES systems Vintech.

The official version of NESPERT is 12, and the new names of the NESPERT systems are:

NESPERT CAM – CAM system for true shape nesting and NC programming (formerly Vintech RCAM)

NESPERT Manager – CAPP/CAM for technological preparation of true shape nesting (formerly Vintech Manager),

NESPERT Duct – CAD/CAM system for parametric design and NC programming by orders for flat patterns of fittings of HVAC systems (formerly Vintech Duct),

NESPERT Pipe – CAM system for NC programming of pipe cutting machines (formerly Vintech Pipe),

NESPERT NCV – verifier of NC programs for thermal cutting (formerly Vintech NCV),

NESPERT MES – system for nesting production management (formerly ViNES)

NESPERT Warehouse – for inventory management for nesting on whole plates and usable remnants, with support of weight, shape and heat No. of plates in different types of storage cells (former ViNES Warehouse-SM),

NESPERT Production – for management of the movements of Nesting layouts in a workshop or area with CNC machines for thermal and jet cutting of true shape nesting (formerly ViNES Production),

NESPERT Operator – for information services of the work on Nesting layouts on a separate or a group of CNC machines by a separate of a group of operators (formerly ViNES Operator),

NESPERT Admin – WEB administration system of NESPERT® (formerly ViNES Admin).

True shape nesting and NC programming with 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 mataerial 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.

Increasing efficiency

The implementation of NESPERT CAM leads to improved time utilisation.

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 auxiliary time to remove parts from the machine table after processing can be reduced considerably by using cutting with bridges, gaps, pseudo-bridges and cutting the scrap skeleton.

Using the above cutting methods allows implementation of work organisation in which CNC machines are loaded to the maximum.

Increasing the quality

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:

Library NESPERT rSales – for express pricing and offering,
library NESPERT rAMT – for cutting technology with parallel torches,
NESPERT NCV – stand-alone system for verification of NC programs,
Technologycal Datasets Base (TDB) for technological information and NC data.

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

Integration of processes and data in the nesting production

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.
