NESPERT CAM

NESPERT CAM creates parts geometry by importing from CAD geometry or by running parametric macros from its own libraries.

• Geometry import
  NESPERT CAM imports parts from 2D CAD geometry or from the projection in the OXY plane of 3D wire-frame geometry.

It can import the following geometry primitives from a CAD file: segments, circular and elliptic arcs, polylines, NURBS splines, point sets and text. While importing the system transforms the CAD primitives into contours, consisting of segments and arcs. Under certain conditions points and text are added to the part so that processing could be done on them.

NESPERT CAM intelligently corrects geometric defects and marks the locations of the remaining errors.

It defines the contour type in the part as: outer and inner closed, hole, slot, geometry for marking and point set. It allows manual changing, enabling/disabling of types of processing as per the layer or the colour of the input contours as well as changing the units of measurement of the input geometry.

NESPERT CAM imports geometry from CAD files with the following formats: DXF, DWG*, SVG, ESSI, DSTV, CDW*, FRW*, PSM*.
Imports geometry from a Rhino .3DM CAD file

If SolidEdge is installed NESPERT CAM can import CAD geometry of plane parts from PSM files, and if KOMPAS-3D/KOMPAS-Graphic is installed – CAD geometry from CDW files.

When a CAD file contains geometry of multiple parts, all of the parts are loaded at the same time without changing their mutual position – as a multipart.
The system loads selected parts from a DXF file, containing multiple AutoCAD blocks.

When the name of file or the AutoCAD block contains quantities, the system automatically fills in the quantities of the parts in the nesting Job.

• Parametric parts
  The library contains a variety of parametric macros. Each macro opens a draft and from the entered dimensions and parameters a part is saved in NESPERT CAM.

NESPERT CAM has a variety of options for nesting control and creating processing technology.

It is possible to perform fully automatic nesting and cutting technology with the push of a button, as well as to interrupt the nesting at any time and work with interactive functions, as well as interactive layout and application of functions for creating and modifying processing technology.

The user interface is visually oriented, with integrated and homogeneous methods for nesting and managing processing technology.

• Project
  NESPERT CAM saves the data during the nesting process in a project file in a folder of the operating system.
  The system supports all necessary data in the project file to allow openning the project both by the user who created it and by a remote user of the system.

• Nesting management
  To manage the design process the system uses Job, Nesting queue, Project navigator, Project tree and galleries – Parts, Blocks and Nesting layouts.

• Plates for nesting in project
  NESPERT CAM nests on multiple whole plates or usable remnants (UR). The system specifies the plates by direct input of dimensions, by a selection from the Plates dataset or by geometry import from CAD file. It allows setting a limit for each plate. It can nest on plates with pre-set sizes in a project.
  Manages inteligently the multiplicity of the plate/nesting layout. Shortens or extends a plate at any time. Creates danger zones for clamps. Defines UR with rectangular, free or stepped form.

• Nesting layouts variants
  NESPERT CAM can disable layouts from the project, after which they become unusable and their parts return for nesting. NESPERT CAM can lock layouts, after which they become uneditable and their parts do not return for nesting. Reports and NC programs can be generated for both locked and disabled layouts.

• Interactive tools for nesting
  The system puts "handles"of the following nesting functions around the objects selected for interactive nesting: continuous and step-by-step rotation, mirror flip, matrix nesting management, automatic snap and dinamic orientation, common cut nesting.

• Creating technology at any time
  Distinctive characteristic of NESPERT CAM is that it can create or change the Processing technology for the whole layout or for a part of it at any time. It is possible to nest parts without technology and to create the cutting technology before generating the NC program. It is also posible to create technology for each part and to nest parts with technology.

True shape nesting

• NESPERT CAM nests with high efficiency.
  It uses algorithms for tight step-by-step nesting and on-line control against overlapping, which does not allow nesting an object on top of already nested ones.
  It has advanced functionality for automatic or interactive nesting.
  NESPERT CAM allows interruption of the auromatic nesting, interactive action and resumption of the automatic nesting at any time.

• Automatic nesting
  For certain angular positions the system optimises, finds place and orientation of a part or a block on the plate and then nests it tightly to the already nested objects. The automatic nesting is performed in the order, set in the nesting queue and with quantities, set in the job, on a single or multiple plates, until the allowed plates or the parts in the job are expended.

• Unlimited part-in-part nesting
  NESPERT CAM nests parts in a hole of another part. The nesting levels are unlimited.

• Interactive nesting
  The nesting in interactive mode can be with true shape or in a pattern, controlled by the corresponding “handles”. Using the cursor they can be dragged, pushed or manipulated until they are placed close to the desired position on the plate. After dropping them, the algorithms for on-line control against overlapping, nest them tightly to the already nested objects on the plate. 

• Special nesting methods
  NESPERT CAM provides functions which take into account the characteristics of the CNC machines such as: nesting on the edge of the plate; common cut nesting; parallel nesting with fixed spacing between the torches and additional nesting after the parallel nesting; parallel nesting with variable spacing and number of torches.

• Working with blocks
  NESPERT CAM includes a large number of functions for working with groups of nested parts, called blocks.
  The blocks can be used as created or broken down and edited on site. Blocks are used everywhere in the system.

• Open database
  NESPERT CAM automates the creation of cutting technologies by taking into account the specifics and requirements of every cutting type - laser, plasma, oxy-fuel, water-jet or mechanical. It saves information according to the ongoing physical and chemical processes inside the cut, the type and thickness of the material and the type of the processed contour. The system supports all repeatedly used information for nesting in the SQL database, which is hidden for the user (i.e. system support is not required). The information in the database is organised in accessible for overview and editing Datasets.

  • Technological Datasets
    NESPERT CAM supports specific technological knowledge in Technological Datasets for Machines, Carriages, Tools, Gases, Postprocessors, Types and Grades of materials, Producers, Processing technologies, Technological tables.
    NESPERT CAM uses them to specify and apply the processing technology to the project based on machine, material grade and thickness, processing type, type and length of the contours.

  • Dataset Plates
    Supports a geometry and the attributive information for Rectangular plates and Usable Remnants (UR). The plates are organized by the following criteria in the dataset: material, thickness, standard, shape – rectangular or complex. The plates can be imported in the dataset through direct input, from CAD files or through saving usable remnants from a nesting layout.

  • Dataset Blocks
    Supports nested groups of parts, organised by material, thickness, machine, energy source, tool and kerf. It is used in repetitive production of parts from the same product.

  • Datasets with work and materials norms
    Supports normative data, needed for pricing and creating offers in datasets: Prices for materials and processing, Company details of customers and suppliers, Additional expenses, Delivery conditions, Settings for pricing.

• Cutting paths and route of rapid moves
  NESPERT CAM provides powerful tools for cutting paths and route of rapid moves management. 

  • Cutting path is the path of the jet, which walks along a separate contour from a part in a way, set by the processing technology.
    NESPERT CAM knows which contours are outer, inner, circular holes, slots, which paths are marked (or engraved), and also which are the centring points.
    The paths are created automatically, with on-line control against overlapping, in correspondence with material, type and length of the contours. NESPERT CAM uses the information from the Technological Datasets to create the paths and path elements associated with them.
    The system finds space for the path elements, so that they do not overlap neighbouring objects, using the on-line control against overlapping. 

  • The route of rapid moves defines the sequence of processing the separate paths in a block, in a zone and in a nesting layout. The route is generated automatically or interactively. 

• NESPERT CAM automatically creates paths for cutting, marking (engraving), cleaning. The visualisation of the paths is performed when a path element is created. The following path element can be automatically created:

  • Start/End points; Gaps; Loops and sharp corner operations,

  • path segments for controlling the speed and acceleration in corners, including radius of roundings for smooth circumvention of corners,

  • path segments for accurate cutting of holes, when the plasma source allows turn-off control.

  • chain cutting with circumventing,

  • fly cutting paths.

• NESPERT CAM interactively creates paths and path elements:
  NESPERT CAM creates:

  • Cutting with bridges; including corner and negative bridges,

  • common cuts,

  • pseudo-bridges with leading line, including on common cuts,

  • paths of parts nested on the edge of the plate,

  • paths with “eyelets” for Lead-In from adjacent path,

  • “L-locks” on the path,

  • chain cutting paths,

  • fly cutting paths.

• Interactive editing
  The system changes the place of Lead-In/Out or Gap by dragging along the path, edits the slope and length of Lead-In and Lead-Out by dragging the relevant „handles“, changes the type of Lead-In/Out using „halos“.

• Transferring a nesting layout between machines
  NESPERT CAM supports powerful functions for transfer of NC programs between different types of machines.
