| Abstract |
Background. During processing on automated lathes topical issue of chip removal from the cutting zone. Specified is implemented by the mode of chip breaking, particularly through the use of the reciprocating movement of the Executive body. The analysis of the dynamic processes that occur when you work mechatronic drive system supply mode of chip breaking.
Materials and methods. The drives of longitudinal and cross feeds of the lathe module including a multi-stage friction gear (FIP), combined with aerostatic guides allow a high degree of accuracy (no slippage) to work out a given law of motion of the caliper with mounted on it a cutting unit, and with the help of this system the chips may be split as by longitudinal cutting and face turning. To achieve a reliable chip breakage with obtaining high quality surface detail allows a multi-stage friction gear (FIP) feed drives. This allows mode to provide chip breaking turning machining of parts of any configuration.
Results. In the processing in the mode of chip breaking on the lathe module type TPARM with aerostatic guides the caliper and laser interferometric sensor feedback ensures high repeatability of slide movement in accordance with a given law of change of
its velocity and effective chip breaking when machining different materials.
Conclusions. Using reverse shaping movements of the caliper with a frequency related to the frequency of rotation of the spindle, in the mode of chip breaking in feed drives precision turning modules allows along with reliable chip breaking is to eliminate built-up edge and get high quality treatment without significant reduction in tool life.
