I. Machining and diagnosis of complex shape objects – Cutting and Forming Tools, Fixtures, Progressive Technologies, CNC Programming, Metrology and Quality
Short description:Production of a complex shape products such as molds for die casting and plastic projecting, dies, but also products of the type of crank shafts, blades of steam turbines, turbo impellers etc., bringing them many material, technological and metrological problems. The activity will be defined by a complete solution of the production chain, from research and development of new advanced technological methods of processing (eg HSC, HPC, dry and hard machining, etc.) and non-conventional technologies (Laser, Sonic, Rapid Prototyping, etc.) and their applications through the construction cutting and forming tools, strategy, motion programming tools and on-line production quality management to analyzing and assessing the resulting quality of the machined object (surface integrity). Activities will be coordinated through existing and optimization algorithms developed in parallel to the application, and at the level SW simulation.

Contract research (examples):
New technology for manufacturing of the exhaust protector fixture
Přípravek slouží jako ochrana držáku výfuku při svařování dalších dílů výfuku proti ulpívání odpadních produktů, které by ve výsledku značně poškozovaly silentblok. Selecting the appropriate mix of machining operations led to savings compared to the original technology by 35%. The result will be protected using proven technology in 2014.

• Improvement of the work performance• Decrease production of bad products• Decrease incapacity and disease from the
career• Improvement physical and psychical
condition of the employees.• Minimization psychical and physical fatigue• Improvement of the psychological climate at
the workplace• The growth company
Major benefits
The ergonomics in repeated manufacturing of small components

16
The ergonomics in the production of the large units
• Productivity improvement• Planning the steps in the individual operations• Simulate the workers activities.• Creating a virtual models of workplace with accurate biomechanical
human model• Detection load of man at his work with using many ergonomics
analyses• Feasibility verification of work activities.
Using these rationalization measures is possible:

The ergonomics in the production of the large units
Wrong
Good location
The collision of move
• Impossibility locomotives rotation around its axis – interfere energy distribution
• Difficult availibility of worker on the welded places – interfere energy distribution
• Problematic of the workers overload

Production Layout
• The space saving• Manipulation reduction.• Minimization logistics activities• Updating and creating the current layout of the production system• Today is usually in the interactive 3D view.• The analysis of the production system with regard to the material creation and other
material flows.• The calculation of the required number of sites storage in production

Simulation and models creation

The simulation should as first verify intended organizational and the measures control and should eliminate the incorrect decision, which it could lead to the problems in the company. Furthermore is possible:• Production increase• Position abate (worker, machine)• Reduce of worker numbers• Risks decrease to go back on terms of contract completion• The ensure faster to start-up of new production• The ensure faster to start-up of the new transport system.
