5 5 Machining Technologies The Main Direction of the R&D  Experimental Machining Laboratory  Metrology Laboratory 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.

6 6 Machining Technologies I. Machining and diagnosis of complex shape objects The design of cutting and forming tools

7 7 The geometry and the quality of the cutting edge Machining Technologies I. Machining and diagnosis of complex shape objects Evaluation of the cutting edge wear using a differential analysis

8 8 The optimization of cutting conditions using modern advanced machining methods – HSC, HPC, HM, DM, MQL,.... The experimental milling of sculptured surfaces and turning in HSC regime Machining Technologies I. Machining and diagnosis of complex shape objects

9 9 Thanks to the original design of the cutting tool (Milling cutter) using advanced ceramics for HSC milling managed to increase machining productivity in many industrial applications up to 400% !!! Tool with technology was awarded.. Machining Technologies I. Machining and diagnosis of complex shape objects

10 10 The measuring instrument "HOMMEL ETAMIC T-800" can be advantageously used for profile measurement, in this case it deals the reverse engineering of the component, for which does not already exist drawing documentation. Machining Technologies I. Machining and diagnosis of complex shape objects

11 11 An example of point scanning of a precise workpiece for automotive industry by CMM (LK - G90 C) Machining Technologies I. Machining and diagnosis of complex shape objects

12 12 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 Machining Technologies I. Machining and diagnosis of complex shape objects

13 13 Contract research (examples): New technology for manufacturing of the molds for pressing catalyst Jedná se o návrh a ověření celkové technologie obrobení formy pro zalisování dílů pláště výfukového tlumiče. Celkový čas výroby byl zkrácen z 65 hod na 40 hod. Ověřená technologie je registrována zn. 8/TECH/KTO/2013 Machining Technologies I. Machining and diagnosis of complex shape objects

14 14  Manufacturing Technology Planning Laboratory II. Virtual Technological Preparation of Production 14 The ergonomics in repeated manufacturing of small components The ergonomics in the production of the large units Production Layout Simulation and models creation Machining Technologies I. Virtual Technological Preparation of Production

15 15 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 Machining Technologies I. Machining and diagnosis of complex shape objects

16 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: Machining Technologies I. Machining and diagnosis of complex shape objects

17 17 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 Machining Technologies I. Machining and diagnosis of complex shape objects

18 18 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 Solutions target and deployment: Machining Technologies I. Machining and diagnosis of complex shape objects

19 19 Simulation and models creation 19 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.
