[0065] Step S20: determining a preset number of milling and milling arcuate segments according to the processing parameters.
[0066] Incidentally, milling and the milling segments are arcuate path different milling, in the absence of the old model of three-axis machining center, by simulating three-axis, within a circular arc and segments based simulation screw thread.
[0067] It will be appreciated that the machining parameters required internal thread milling, threading specific information may be obtained, according to the specific information required to determine these require milling and a number of arc segments by calculating, for example, known internal thread to be machined parameters, pitch obtained in particular during milling some of the need to ensure accuracy, the minimum error can be obtained, according to the pitch and the same minimum error can be obtained and the number of arcuate segments, arcs and segments by division calculations, in particular the greater the number of arcs and segments selected during milling, the higher the accuracy of the milling.

[0069] Incidentally, three-axis generally refers to X, Y, Z three-axis associated actions can be realized simultaneously, typically in the X-axis lathe carriage means around, Y axis carriage means, Z axis refers to the spindle. Then the third shaft axis linkage before synchronization may be implemented as a three axis-related action, the two axes may be associated with synchronization action, additional action to achieve a single axis, to two axes may be associated with synchronization operation, the two axes in either axis linkage, for example, to the car taper thread, it must move forward with the XY axis, YZ also with another forward, that is the three-axis motion must be associated with, so as to drive the tapered thread .

[0093] It will be appreciated that the segment path during milling simulation, determined the line path axis milling operation is required, when simulating milling a circular path, the plane has been determined circular path milling, then the milling path simulation time segment, Face milling circular path perpendicular to the path line segment of the milling, the milling arcuate linkage is not performed for the third operating shaft axis, such as milling in a circular path XOY plane, respectively in the Z-axis path line milling operation is axis, i.e., the third axis to be linked.
[0094] Step S3043: based on the start of the second path of the milling, the milling of the current path segment for milling simulation linkage third shaft, milling to obtain the second path.
[0095] Incidentally, the second path is the current milling path milling simulation segment, the starting point of the path to the end of the first path.
[0096] It will be appreciated that, after the start of the second milling path is determined using the third axis to simulate the milling path segment, the segment path milling path simulation within the simulated as a space surrounded by, the third shaft is sufficient to simulate the milling path segment .

[0098] It will be appreciated that the starting point is the new processing subsequent milling path simulation processing starting, the internal thread milling path is a continuous path, the path need to connect all milling, milling places the end of the second current path is traversed as milling the starting point of the arc, that is a new starting point.
[0099] Incidentally, in the step S302 and the current traversing this arc milling milling segment, after completion of the second analog path milling, milling arc re-select the current line segment and the current milling path milling simulation is performed next.
[0100] It will be appreciated that, subsequent milling of the arc current and the current selected milling segments in the subsequent milling and milling arcuate segments range after milling arc current and first current line selected milling, milling in a circle before to give arcuate path repeated milling and the milling segments and arc current after milling simulation segment.
[0101] Step S306: At the end of traverse, to be acquired within the milling path the thread milling.
[0102] It will be appreciated that the milling path is to be machined internal thread milling path, is in the range of milling and milling arcuate end segments traversed, the path of the internal thread milling simulation is completed, the milling path to obtain an internal thread.

The processing parameters of the thread to be milled, and select the best milling arcuate segments milling specifications, for example, in a case where the thread milling to be determined, selected arc 1 / 4,1 / 8 or specification is 1/16 milling simulation circular path, select the 1/8 circular arc as the circular arc milling in the present embodiment as an example, the specific required specifications determined according to the selected processing parameters internal thread.
[0113] Step S203 is a step corresponding to S203 ': The size of the milling and milling arc segment size, the pitch and the error threshold determining a preset number of milling and milling arcuate segments.
