Control Cards Design in Process Manufacturing

Violina Georgieva and Alexander Hadjidimitrov

https://doi.org/10.6025/isej/2023/10/2/31-37

Abstract In process manufacturing, control over the process is often more important than control over the product. In production departments, operations and quality control are registered with “Control cards.” Control cards are then used to analyze defects, claims, machine and employee loads, etc.... Read More


Auto-calibration Frequency and the Coarse Error Elimination

Dragan Denic, Goran Miljkovic, Jelena Lukic, Miodrag Arsic and Milan Simic

Abstract WHAT IS THE PROPOSAL FOR THE POSITION METERING TECHNIQUE? The position measurement method is performed with a hybrid pseudo encoder deactivated by combining the pseudo encoder with the incremental code track. The combination of the two code tracks improves the measurement resolution. The proposed hybrid pseudo encoder includes the detector for the pseudo-code reading errors. This helps to decrease the autocalibration... Read More


Converter Design for Serial Pseudo and Natural Code

Dragan Denic, Goran Miljkovic, Jelena Lukic, Miodrag Arsic and Dragan Živanovic

Abstract Pseudorandom / natural code conversion time is the most important factor for the absolute position measurement cycle when using the pseudorandom positions encoder. Serial code converters are simple to implement and have advantages over other converters. In this paper, we provide examples of serial pseudo / natural code converters and a proposal for a new, faster converter.... Read More


Destructive Testing Design for Surface Mounting

Valentin Videkov, Aleksei Stratev, Georgi Furkov

https://doi.org/10.6025/isej/2023/10/2/51-57

Abstract This paper reviews cutting methods to perform destructive testing for surface mounting. Demonstrates two ways of controlling processes during the production of technology equipment and process control. Demonstrates experimental results from a process for the production of laser-cut stencils.... Read More
