Subject content

Measuring systems for determining values of process parameers in the technological processes of garment cutting, joining and finishing. Sensors and measurement methods for determining the operating speed of machine parts, material feeding, forces, penetration force, angle acceleration and workpiece acceleration, friction, power and energy. Measuring signal conditioning, measuring amplifiers, filters, conversion of measurement data, synchronization of measuremnt and control computer systems, data storage. Measurement data processing, statistical and numerical methods. Development and application of measurement systems for characteristic technological procedures of garment production. Integration of the measurement system with the designed workplace in the laboratory environment and production process. Development of the program support for measurement, acquisition and data processing, calculation and analysis of process parameters. Procedure for determining new process parameters in conventional production processes. Investigations, measurements and analysis of process parameters in contemporary technological cutting processes by NC units, laser and ultrasonic instruments and hot patterns, by laminating joining processes, ultrasonics, conduction and convection of heat.

Aim of course

Students become familiar with scientific research methods of determining process parameters of technological procedures of garment manufacturing, with elements of measuring systems, measurement methods and numerical analysis of process parameters. The student familiarizes himself/herself with research methodology and acquires knowledge of individual research work in determining, measuring and analyzing process parameters.
