Streszczenie / Summary:

This paper evaluates, considering a practical perspective, the methods of research in times of
assembly processes performed by workers i.e. time study, working day’s activity study, MTM,
MOST and Work-Factor during assembly of a milling machine spindle in JAFO S.A. factory.
This research is substantiated and methods of research in time of assembly processes are discussed.
A review of presented methods is made and their strengths and weaknesses are discussed.
The article presents results of studies in assembly time of a CNC milling machine spindle using
five time observation methodologies. The operation under consideration is divided into seven
stages. On the basis of the literature and authors’ research a practical evaluation is made considering
methods of measuring time consumed by assembly of a spindle of a CNC milling machine.
Principles of selecting appropriate methods for specific situations in industrial practice are discussed.
