Abstract
The invention discloses an interpolating-free machine tool machining method. At present, trajectories of parts machined by a machine tool are machined in an interpolating mode, multiple motors are required to conduct motion, and thus the part machining accuracy is lowered due to the fact that a larger error is generated between interpolating machining and multi-motor motion. The method includes the steps that profiles of the parts to be machined are segmented according to machining requirements of straight lines and circular arcs, and the machining segment content and machining sequence of each line to be machined are determined; the parts to be machined are placed on a workpiece fixing piece, meanwhile a cuter is placed at the start point, then whether the first machining line is a straight line or a circular arc is judged, and machining is conducted according to features of different lines; finally, whether unfinished lines to be machined exist or not is judged, and if yes, the next line to be machined is machined till all the lines to be machined are machined. By means of the method, the accuracy of the motion trajectories can be improved, the interpolating-free machine tool machining method is suitable for being used for occasions with a higher requirement for motion trajectory control, and particularly for fine machining and nanometer machining which are very high in control accuracy requirement, the method can eliminate the interpolating error.
Description
Technical field
The invention belongs to machine tooling field, relate to a kind of without interpolation processing method, being specifically related to when needing the circular arc part of the angled oblique line of processing belt and radian can without the method for linear interpolation and circular interpolation.The method can avoid part to add the error caused due to interpolation and many motor movements man-hour, can improve the precision of part processing like this.
Background technology
As a kind of processing method, the element precision processed is the important indicator weighing part quality.The machining accuracy of part affects by several factors.Wherein the interpolation of Digit Control Machine Tool can affect the precision of part processing.Interpolation is the process that machine tool numerical control system determines cutting tool path according to pattern.Alternatively, some data on known curve, calculate the method for the intermediate point between known point, also referred to as " densification of data point " according to certain algorithm; Data densification, according to the information of the parts program of input, is carried out in space between the starting point of the curve described by program segment, terminal by numerical control device, thus forms the profile traces required, this " data densification " function is just called " interpolation ".In Digit Control Machine Tool, the curvilinear motion that cutter can not strictly be processed as requested, can only approach curve to be processed by dog-leg path.
The classification of interpolation: the profile of a part is diversified often, there is straight line, there is circular arc, also be likely arbitrary curve, line transect etc. the cutter of Digit Control Machine Tool can not go feed with the TP of curve often, but go feed with some very little straight lines approx, the direction of feed is generally X and Y-direction.Interpolation mode has: linear interpolation, circular interpolation, parabolic interpolation, line transect interpolation etc.
Interpolation principle: in the motion control of numerically controlled lathe, the minimum Moving Unit of workbench (cutter) X, Y, Z axis is a pulse equivalency.Therefore, the movement locus of cutter has the broken line (data point densification) that minimum step forms.Such as, with lathe in machining straight line OA, curve OB, cutter moves along X-axis to move a step or a few step (one or several pulse equivalency Dx), then move along Y direction and move a step or a few step (one or several pulse equivalency Dy), until arrive impact point.Thus the movement locus (straight line or curve) needed for synthesis.Digital control system, according to given straight line, circular arc (curve) function, between the known point on desirable track, is carried out data point densification, is determined the method for some intermediate points, be called interpolation.
The track of current machine tooling part be all with interpolation mode to complete the processing of parts profile, therefore have error of interpolation.Need to control multiple motor associated movement to complete movement locus during interpolation simultaneously, when controlling multiple motor because control signal needs process send and have delay to response, the pulse that control system sends also can lose step phenomenon in some cases, and these also can cause multiple motor cannot accomplish synchronous and make movement locus have error.
How effectively solving these major issues, the present invention can not adopt the mode of interpolation to carry out processing parts, and adding the motion reducing kinematic axis man-hour, the track such as directly taken the air line during processing linear, directly rotates during Machining Arc on disk simultaneously.So fundamentally solve error of interpolation and the error that causes of lathe multi_motor control of part processing.
Summary of the invention
The object of the invention is for when processing is more and more higher to required precision now, from the error reducing process principle error and lathe manufacture itself and control, the error having interpolation and multi_motor control to produce can be considered for error analysis, propose a kind of lathe without interpolation processing method.This processing method can reduce the generation of error from source.
Method of the present invention is based on lower device, this device increases by three kinematic axis in addition on existing platen, a rotating shaft, two shifting axles respectively, specifically disk is flexibly connected with existing platen by rotating shaft, realize rotary motion, the motor of this rotating shaft lower end and lathe or transmission mechanism output shaft are connected simultaneously, are driven by motor or transmission mechanism; The cross slid platform be made up of two shifting axles is fixed on disk, and realizes X-axis, Y-axis rectilinear motion by slide rail; Shifting axle above cross slid platform is positioned at is provided with the workpiece firmware for clamping part to be processed, and the shifting axle that this workpiece firmware is positioned at top by slide rail along cross slid platform moves linearly;
