Description
Technical field:
The present invention relates generally to the method that numerically-controlled machine is provided with the amount of feeding.
Background technology:
The feed mechanism driving-chain of engine lathe is that the main shaft with lathe connects together, national Specification with main shaft revolution lathe tool move what the distance be the set-up mode of the lathe amount of feeding of correlation parameter, so both satisfy conventional feeding, formed spiral trajectory accurately when having guaranteed machining screw again.
After numerically controlled lathe occurs, the lathe amount of feeding is at the afterbody of lathe spindle the rotary speed data that scrambler is gathered main shaft to be installed, be transferred to digital control system, the operator is provided with the amount of feeding parameter that needs processing by the mode of writing code, the motion of digital control system control feed mechanism, the displacement of realization main shaft revolution lathe tool.
Numerically controlled lathe is provided with the mode of the amount of feeding at present, is to adopt the mode of numerical control programming that parameters such as long feed amount, traverse feed amount, metric thread, inch screw thread, modulus screw thread, pitch thread are set.Main G code and the M code programming of adopting carries out process operation by digital control system, and fabrication cycles can be set.Lathe in machining program and engine lathe technological procedure have bigger difference, the content that relates to is more extensive, the programming technique personnel not only will have gained some understanding to performance, characteristics and the method for operation of numerically controlled lathe, and are also all very familiar to the mounting means of tooling system, cutting parameter and workpiece.
Said method is generally adopted on existing numerically controlled lathe, and the problem of existence is that the operator for numerically controlled lathe has relatively high expectations, and must seriously limit the large-scale promotion of numerically controlled lathe through special training.
