METHOD FOR CONTROLLING TOOL SHIFTING VELOCITY IN SCREW MANUFACTURING USING NC MACHINE

摘要

How is initiated to control the feed rate of the threading using a numerical control device tool (T) The. The process according to the invention comprises: (a) the absolute position of the workpiece (W) (0, 1, 2, ... N-1) and obtaining, (b) the work (W) is the absolute position (0, 1, 2 ... N-1) through a step of checking that the reference point (0) from and, (c) when the workpiece (W) is passing through the reference point (0), work (W) from the origin exceeds measuring the amount (E) by the rotation and, (d) the feed shaft (Z axis), the distance (D ₂ ) corresponding to the excess amount of rotation (E) of the workpiece (W) and obtaining step, (e) and the target feed rate (V) of the tool, the distance between the tool (T) of the transfer point (B) and the cutting point (C) (D ₁ ) and wherein the workpiece (W), and an axis (Z-axis) corresponds to the excess amount of rotation (E) of the distance (D ₂ ) to transfer acceleration (A ') of the tool (T) from the following formula: obtaining by the A '= V ² / 2 (D ₁ - D ₂ ) in that it comprises a features.
