Supervisor: | Ing. Aleš Polzer, Ph.D. | |||
Supervising institute: | ÚVSSR | |||
Teaching language: | Czech | |||
Aims of the course unit: | ||||
The main goal of the course is to deepen practical knowledge and experience in controlling selected CAD and CAM software, control system (Sinumerik, Datron NEXT etc.) CNC machines and specialized contact CMM or optical measuring instruments controlled by their specialized software (eg: CCI optical roughness tester from Taylor Hobson, optical SOL 311 profilometer from Micro-Vu, contact 3D coordinate measuring machine Eclipse 1000 from Zeiss).
The graduate's ability to appropriately choose machining strategies on CNC machines with regard to machine design (performance parameters, machine kinematics, etc.) and with regard to the quality of the resulting workpiece (integrity of the machined surface, etc.). |

Learning outcomes and competences: | ||||
The graduate's ability to appropriately choose machining strategies on CNC machines with regard to machine design (performance parameters, machine kinematics, etc.) and with regard to the quality of the resulting workpiece (integrity of the machined surface, etc.). |
||||
Prerequisites: | ||||
Basics of technical drawing. |
||||
Course contents: | ||||
Programming for the production and evaluation of the quality of the workpieces according to the selected machining strategies: - workshop-oriented NC programming according to the drawing from CAD (Sinumerik), - ISO NC programming according to drawings from CAD (with cycles and parametric - Sinumerik), - programming in CAM according to 3D models (Inventor CAD/CAM or SolidWorks CAD/CAM), - programming of the measuring profile projector via dxf files (SOL 311 / InSpec), - programming templates for automating the evaluation of surface texture parameters (TH CCI / TalyProfile), - CMM programming (Eclipse 1000 / Calypso). The course is designed as a combination of knowledge of the basics of machine tool design, production on CNC machining centers and measurement of workpiece parameters. The basics of design performed in CAD software are applied to simple examples of workpiece parts. Increased emphasis is placed on the technological design with respect to machining in NC/CAM software. Differences in usable strategies and procedures in machining are evaluated in terms of the integrity of machined surfaces and the overall quality of products. |
||||
Teaching methods and criteria: | ||||
Teaching in exercises and in labs is realized with the support of modern computer technology: specialized SW and HW. |
||||
Assesment methods and criteria linked to learning outcomes: | ||||
A graded credit will be awarded on the basis of the achieved results of independently performed tasks (eg: design, NC programming, measurement) in exercises / laboratories. The final exam will test theoretical and practical knowledge of the subject matter: in the form of a brief test (5-10 questions) and individual work (30-60 min) in CAD, CAM, CMM or Sinumerik control system of the machine tool. |
||||
Controlled participation in lessons: | ||||
Student participation in exercises and laboratories is mandatory and checked regularly. Missed exercises / laboratories can be replaced by processing, for example, a brief search on a given topic (details consulted with the teacher in advance). A maximum of four unexcused / unreplaced absences per semester are allowed. |
