In engineering industry the production of components begins with separation of the base material and this technological operation can be time consuming, especially in large-scale production. Such production can be made more efficient by means of laser technology focusing on material cutting. Efficiency of cutting is determined not only by shortening of working time or energy saving, but also by the required cutting quality. In the paper we compare the impact of cutting speed changing and laser beam performance on the cutting edge quality. Based on requirements of dimensional accuracy and preset roughness of the cutting edge, we evaluated the cutting quality of laser in samples of different materials. Measured values of sample dimensions and roughness are compared in conclusions of the paper, where we estimate whether the samples meet specified requirements of dimensional accuracy and roughness of the cutting edge in order to make the production process more efficient.

ncrease in the number of orders, the increasing quality requirements and the speed of order preparation require implementation of new solutions and improvement of logistics processes. Any disruption that occurs during execution of an order often leads to customer dissatisfaction, as well as loss of his/her confidence. The article presents a case study of the use of quality engineering methods and tools to improve the e-commerce logistic process. This made it possible to identify and prioritize key issues, identify their causes, and formulate improvement and prevention measures.

All recent experiences confirm the fact that the main tasks of quality management are guaranteed only with the high skilled employees. Employees are responsible for the production plan and development, services and processes. The series of standards called ISO 9000 help to establish quality management in organization. Usage of the quality management with statistical process control is also very important for the company. Companies are spending all human, material and financial resources to improve quality management. The objective of the paper is to outline the statistical process control in production company Finalcast Ltd. Žiar nad Hronom.

Wszystkie ostatnie doświadczenia potwierdzają fakt, że główne zadania zarządzania jakością są gwarantowane tylko z wysoko wykwalifikowanymi pracownikami. Pracownicy są odpowiedzialni za plan produkcji i rozwoju, usług i procesów. Seria norm ISO 9000 jest pomocna w celu ustalenia zarządzania jakością w organizacji. Korzystanie w zarządzaniu jakością ze statystycznej kontroli procesu jest również bardzo ważne dla firmy. Firmy wykorzystują wszystkie zasoby ludzkie, materialne i finansowe w celu poprawy jakości zarządzania. Celem pracy jest określenie statystycznego sterowania procesem w produkcji firmy Finalcast Ltd. Žiar nad Hronom.
