ABSTRACT:
A process for copying and threading in automatic square cycle, applicable to and/or incorporated into engine lathes in general, includes material removing machining of parts by copying method in automatic square cycle, providing during the machining an automatic feed system for depth of cut with programmable and progressive increments through electric means, cutting of threads on a surface of the machined parts in automatic square cycle, and providing during the cutting an automatic feed system for depth of cut with programmable and progressive increments through electric means. A device for the process includes a longitudinal carriage with a cross slide having a bottom swiveling support and a copy carriage mounted to the latter, a longitudinal support for a tool with a tool holder and attached on an upper swiveling support fixed on an upper face of the copy carriage, a movable first arm fixed at a corner of the copy carriage, a head equipped with a copy valve having a stylus and an assembly mounting templates, a hydraulic unit mounted on the longitudinal carriage, first and second sets of time relays mounted on a programming panel, a first set of electric switches for programming the first set of time relays of the automatic feed system for depth of cut when in copying cycle, a second set of electric switches for programming the second set of time relays of the automatic feed system for depth of cut when in thread cutting cycle, and a control panel containing an electric selecting switch for pre-positioning of copy and thread cutting automatic cycles and a button for starting the automatic cycle.
