В статті розглянуті сучасні тенденції розвитку верстатів з паралельною структурою у
машинобудуванні та металообробці. Проведено дослідження по вибору раціональнішого варіанту
компоновки верстата «пентапод» за параметрами робочого простору і жорсткості. The aim of the article is to choose the layout of pentapod parallel kinematic machine after the criteria of
workspace and spatial rigidity.
Several configurations with different arrangement of joints on a stationary platform are considered. The
geometrical method is used to determine the workspace, and spatial rigidity is calculated using machine
kinematics. It’s proved that the workspace of each configuration has a complex geometric shape. Workspace
volume and shape significantly depend on the arrangement of joints, which also affects the output specifications
of the machine and its ability to process certain parts.
The conducted analysis made it possible to choose the layout of the machine according to customer
requirements on stiffness and workspace.
