Abstract
An automatic machining process using a programmed machining cycle, in which process a component previously machined according to the program is used to sense deviations from the expected component shape, such deviations being employed to effect corrective tool off-sets in the aforesaid or a subsequent machining cycle. The invention also embraces a machine tool capable of performing this process.
Claims14
An automatic machining process for the production of a component according to a predetermined programme, comprising moving a member automatically through a machining cycle acording to said programme and simultaneously causing a monitoring device to be correspondingly traversed in a path determined by the programme over a component previously machined according to the programme, so as to sense deviations from the expected component shape appearing in the previously machined component, and using said deviations to effect corresponding corrective tool off-sets in one of the aforesaid and a subsequent machining cycle.
An automatic machine tool capable of performing a machining cycle automatically according to a predetermined programme to produce a desired component, said machine tool including means for supporting a component previously machined according to said programme, monitoring means arranged to traverse said component in a path determined by the programme whereby deviation from the expected component shape appearing in the component are sensed, means for converting sensed deviations into error signals and correcting means responsive to said signals to effect corrective tool off-sets in one of the aforesaid and a subsequent machining cycle.
