The analysis of orders nomenclature shows that from 70 to 90% of furniture enterprises requirements in shaped cutting are satisfied by hybrid algorithm designed by «Bazis-Center». It combines algorithms of regular cutting and control programs automatic creation for machines with Nesting functions (pseudo-nesting technology). This process is realized in three stages:
- material is cut according to selected optimization criteria and technological settings;
- BAZIS system file with generated cutting charts will be created;
- control program for particular machine will be created in BAZIS-CNC module.
Cutting charts will be generated after particular technological settings execution completion. They do not differ visually from cutting charts for round-saw machines. Simultaneously, the system creates a file that contains cutting charts in the form of combined panels, i.e. panels of BAZIS system format, contour, boring and many grooves that build an assemblage of corresponding elements of the panels placed on a chart. The panels are orientated automatically in a way, that faces with big number of holes and grooves are placed at one side of combined panel. It allows to execute many operations at one stage of processing.
Combined panels set is transferred to BAZIS-CNC module for control programs generation. There is a capability of operations sequence specification for Nesting technology.
Undoubtedly, pseudo-nesting technology is not a full-fledged solution to shaped cutting optimization in furniture production. However it allows to solve a wide range of designing tasks fast and efficiently.
One of applied problems that can be solved via pseudo-nesting technology is front panels milling and cutting. If front panels are arranged on initial MDF board, cutting chart and file for BAZIS-CNC module will be created that allows to execute all technological operation in optimal sequence, i.e.:
- grooves milling on face;
- front panels edges rounding on MDF board;
- handle holes boring;
- linear cuts milling, i.e. board division into separate panels;
Because the front panels are rectangular, material consumption ratio will be always maximum possible.
