Run trade-off studies with different tools to see which fits your machine best. Evaluate the benefits of that expensive high-end endmill before buying it. Does a higher helix angle make sense for your needs? Better to increase width of cut or run more passes at higher feed? Millalyzer hands you the data, you decide. https://www.larosterna.com/millalyzer/hl-crazyfast/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/millalyzer/hl-crazyfast/ Any analysis completes in seconds, even process optimisation! https://www.larosterna.com/vzm/collision-detection/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/vzm/collision-detection/ Collision checks can be run for either one single or a large number of programs at once, without any need for user intervention. Results are displayed by highlighting the colliding parts or can be exported to report files. A vectorized (SSE, AVX) multi-core implementation makes full use of modern CPUs such that finely resolved, very long programs and complex machine models can handled efficiently. The collision detection algorithm can be configured to require a minimum distance between parts instead of hard collisions, exclude some parts from testing, and to optionally stop at the first collision for increased efficiency in NC program validation. https://www.larosterna.com/vzm/use-verification/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/vzm/use-verification/ More and more often, programs for NC machines are generated automatically or by means of off-line programming solutions. Such programs need to be checked for correctness, collisions and reachability constraints. https://www.larosterna.com/millalyzer/milling-tools/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/millalyzer/milling-tools/ Millalyzer’s tool definition interface is entirely open, the built-in tool editor lets you quickly define new endmills. Choose to define only the most important properties or enter all detail dimensions for accurate chatter analysis. Tool library files are plain-text files in YAML or CSV format, and can be saved and loaded freely. Wondering whether those expensive high-end endmills with unequal helix angles and flute indexing make a difference? Millalyzer lets you try it out. https://www.larosterna.com/vzm/use-performance/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/vzm/use-performance/ Analysis of machine program performance often reveals considerable potential for improvement. A simulation based on high-accuracy controller emulation reveals whether dynamic machine limits are reached how bottlenecks can be avoided. https://www.larosterna.com/vzm/performance-analysis/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/vzm/performance-analysis/ Interfacing with a high-quality controller emulator such as the Siemens Virtual NC Kernel (VNCK, xMVM) enables the collection of very accurate, detailed program timing data. Graphical representations of performance limitations can then be used to detect slow NC code paths and improve the performance of existing machines. https://www.larosterna.com/millalyzer/hl-science/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/millalyzer/hl-science/ Well-founded numerical model, not just rules of thumb. https://www.larosterna.com/oss/ Thu, 25 Jan 2024 11:49:00 +0000 https://www.larosterna.com/oss/ As part of research at the Royal Institute of Technology, software for aerodynamic/structural/aeroelastic modeling of aircraft was developed. This includes mesh generation capabilities and post-processing tools for the results of aeroelastic analyses, e.g. for the determination of gust loads or aeroelastic stability evaluation. This software can be used freely under the terms of the GPL. scope for Linux (requires libc >= 2.28) sumo for Linux (requires libc >= 2.28) scope+sumo for Windows The current (January 2024) source code for scope and sumo can be found here. https://www.larosterna.com/vzm/afp/ Mon, 27 Nov 2023 14:22:00 +0100 https://www.larosterna.com/vzm/afp/ The process of composite material deposition by Automated Fiber Placement (AFP) machines can be simulated as well. Gaps in the layup become immediately visible and errors in machine program generation are detected quickly. Statistics computed based the geometry of the deposited laminate provide insight in how AFP machine productivity can be improved. Optionally, empirical information on production process interruptions (such as AFP cutter cleaning) can be entered for more realistic, material-dependent productivity estimates. https://www.larosterna.com/millalyzer/hl-database/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/millalyzer/hl-database/ Carefully assembled flow-stress models means material behaviour is accounted for. https://www.larosterna.com/vzm/use-planning/ Mon, 27 Nov 2023 10:22:00 +0100 https://www.larosterna.com/vzm/use-planning/ Machine vendors, system integrators and factory planners can use VZM to evaluate the benefit of different machine kinematics, jigs and fixtures for a production facility during planning and development. https://www.larosterna.com/vzm/interfaces/ Mon, 27 Nov 2023 14:22:00 +0100 https://www.larosterna.com/vzm/interfaces/ Machine and workpiece geometry can be imported from files in STL or 3DXML format. Such files contain tessellated geometry and can often be accessed directly from machine manufacturer websites or generated by any CAD software. Hole and fastener data can be loaded from IGES or plain text files for maximum flexibility. Engineering data such as reference curves or composite layup information, tow masks and trimming geometry can additionally be imported from IGES or other open formats. https://www.larosterna.com/millalyzer/optimization/ Mon, 27 Nov 2023 12:14:00 +0100 https://www.larosterna.com/millalyzer/optimization/ Let millalyzer find the maximum acceptable width or depth of cut, in seconds.

Larosterna is a fairly large tern breeding along the coasts of the Humboldt current. It is quite a beautiful creature wearing a stylish snow-white mustache (really!), grey coat and black hat fashionably accompanied by red accents.

For many specialized systems such as tripods or C-frame riveting machines, pre-defined dialogs are available, while a very general spline-based interpolation approach can be employed to model innovative systems that cannot be modelled at all by some other simulation systems. As an example, VZM was used to generate development-stage drilling programs for a crawler device that is moving along a doubly-curved surface, at very competitive cost. https://www.larosterna.com/millalyzer/materials/ Mon, 27 Nov 2023 12:14:00 +0100 https://www.larosterna.com/millalyzer/materials/ The built-in material database contains flow stress models and thermal data for a range of common aluminum and steel alloys. Models are not simple empirical relations, but based on research published by NPL, the Lawrence Livermore National Laboratory and many others. More materials will be added in the future and existing properties will be improved following the analysis of recently performed cutting tests.

Both versions can predict cutting forces reliably; find optimal cutter engagement values; define machine & spindle constraints; warn for premature tool failure. while the dynamic version, additionally, simulates elastic tool motion; helps to avoid excessive chatter.
