Abstract
The invention provides a machining standard adjusting method for numerical control machining of a large casting. The method comprises the steps of: 1) establishing measuring points on a non-machining surface corresponding to a machining surface of the large casting; 2) transporting three coordinate data X, Y and Z of the established measuring points as well as corresponding vector data into a three-coordinate measuring machine; 3) analyzing the data by the three-coordinate measuring machine to obtain the actual measuring values of the measuring points; 4) comparing the actual measuring values of the measuring points with the theoretical values of the measuring points to obtain a difference value which is the standard adjusting rate in the machining; and 5) adjusting the machining standard in the numerical control machining of the large casting based on the difference value. The method provided by the invention is simple to carry out, and has high precision and high efficiency, and can effectively solve the problem of large selection difference for the machining standard caused by excessive data and excessive coordination dimensions.
Description
Technical field
The invention relates to the method for adjustment of machining benchmark in a kind of heavy castings digital control processing, and the benchmark that is mainly used in the medium-and-large-sized foundry goods of digital control processing is chosen and adjusted.
Background technology
In field of machining, because pts wt is big, size is big for heavy castings; Complex-shaped; Be difficult for turn-over and line, on three coordinate measuring machine, measure processed machine usually and add the spatial data that face obtains part, analyze data then; And then the adjustment machining benchmark, prepare digital control processing.And adopt this method to need data measured more usually, the allowance size of being stayed is more, therefore between bad coordination, finally can cause choosing of heavy castings reference data too big with actual deviation, make the part scrappage high.
Summary of the invention
The purpose of the invention provides the method for adjustment of machining benchmark in a kind of heavy castings digital control processing, and process is simple, and the degree of accuracy is high, and efficient is high, can solve machining benchmarks many owing to data and that cooperative dimensioning causes more and choose the big problem of deviation.
The technical scheme of the invention: the method for adjustment of machining benchmark in the heavy castings digital control processing may further comprise the steps:
1) adding the corresponding non-machine of face at the heavy castings machine adds and sets up the measurement point position on the face;
2) three-dimensional data X, Y, Z and the vector data corresponding with it with the measurement point position of setting up is conveyed into three coordinate measuring machine;
3) three coordinate measuring machine draws the measured value of measurement point position after analyzing data;
4) measured value of measurement point position is compared with the theoretical value of measurement point position draw deviate, deviate is the benchmark adjustment amount that adds man-hour;
5) the last adjustment of accomplishing machining benchmark in the heavy castings digital control processing according to deviate.
The beneficial effect of the invention: add at the non-machine of heavy castings and to choose measurement data on the face and set up the measurement point position; Can reduce data computing and coordination; Only need to draw the benchmark adjustment amount that adds man-hour, thereby confirm the machining benchmark of numerical control according to the deviate behind the three coordinate measuring engine measurement.
