Abstract: A method for roughening a cylinder bore wall to be coated of a component, at least one groove, running around the central longitudinal axis, and at least one associated groove web, are generated such that the at least one groove web, in a radial direction directed toward the central longitudinal axis, forms first undercuts for a coating which is to be applied. Axial grooves running in the cylinder bore wall transversely to the at least one groove are generated such that the at least one groove web, in a peripheral direction about the central longitudinal axis, forms respective second undercuts for the coating which is to be applied. An adhesion of the coating which is to be applied, in the peripheral direction, is improved, so that stress cracks or detachments owing to a different thermal expansion of the component and of the coating which is to be applied are avoided.

Abstract: A detection device for the seating detection of an object on a clamping device includes a measuring chamber with an inflow opening to supply a detection fluid from a pressure source, at least one outflow opening to discharge the detection fluid to a pressure sink and with at least one detection opening, which can be closed at least partially by the object abutting on the clamping device. An inflow resistance limits an inflow of the detection fluid via the inflow opening, at least one outflow resistance limits an outflow of the detection fluid via the at least one outflow opening and a pressure sensor determines a pressure of the detection fluid in the measuring chamber.
