Individually configurable automatic cost calculation system for 3-d laser cutting (ICACOST)

Objective

At present, small and medium-sized enterprises (SME's) in the sheet metal industry have to invest much time in At present, small arid medium-sized enterprises (SME) of the sheet metal industry have to invest much time in offer preparations, because of the low probability of getting the job. The offer calculation is mostly done manually as an estimation. For example, the length of the contours to be cut are extracted from drawingsand summed up. Actual production time for workpiece problem areas like sharp angles and narrow radii can only be calculated by a post-prossesor simulation or by a comparison with a similar workpiece that was manufactured before. This complicates the cost calculation and adds an unsureness factor to calculation. Therefore, only experienced employees can estimate the costs for the cutting of 3-d workpieces. The aim of the proposed software ICACOST is the quick and automatic cost calculation for 3d laser cutting. Less experienced persons shall be able to use the configured tool. Therefore, characteristic numbers are generated on the basis of the workpiece geometry. They describe all necessary machine work to perform and the workpiece specific problem areas. As next step, the dynamic machine behaviour for these problem areas is projected to specific machine parameters. By connecting the characteristic numbers with the machine parameters, the machining time for a specific machine is calculated. This machining time is an important factor for the cost calculation. The characteristic numbers are also used to find similar workpieces within the planned offer database. This database is also implemented during the project and contains all created offers. As plausibility check the user can search for similar offers and compare them with the new one. A complete cost calculation must include all costs which are important for the production, not only the machining time. These diverse parameters come from various sources, and must be combined with each othe
