Embodiment

[0054] Please refer to Figure 1-3 , the present embodiment provides a man-hour prediction method for the machining process of aircraft structural parts, comprising the following steps:

[0055] S10: collecting sample parts.

[0056] Exemplarily, collect sample data of working hours of each process of parts of different sizes and types, and filter out the data samples of parts with countless models, incomplete process information, and abnormal working hours to obtain sample parts; Complete and abnormal part data samples are used to obtain sample parts. Such sample parts are fully representative and improve the accuracy of analysis results.

[0057] S20: process division; according to the processing process of each sample part, it is divided into a fixed man-hour process and a variable man-hour process according to the processing attributes.

[0058] The characteristic of the fixed working hours process is that it is less affected by the nature of the parts themselves, such a...

Abstract

The invention discloses a method for predicting working hours of airplane structural part processing procedures, and relates to the technical field of aircraft structural members, and the method comprises the steps: collecting sample parts; dividing processing procedures of each sample part into a quota man-hour procedure and a variable man-hour procedure according to processing attributes; for the quota man-hour process, determining the structure type, and dividing sample part types according to the structure characteristics of the sample parts; dividing size intervals, dividing the sample parts into the corresponding size intervals according to the lengths, the widths and the thicknesses of the sample parts, wherein each size interval corresponds to working hours; and inputting the size interval and the man-hour corresponding to each sample part into a man-hour library to establish a general quota man-hour library. The problem of large error of manual evaluation of the machining time before part machining is solved, the influence factors of the process can be quantified, the machining time can be quickly and accurately predicted, the universality is high, and the expandability is high.

Description

technical field [0001] The invention relates to the technical field of aircraft structural parts, in particular to a man-hour prediction method for the machining process of aircraft structural parts. Background technique [0002] At present, the processing of aircraft structural parts has the characteristics of multiple varieties and small batches. For manufacturing enterprises, the research on the man-hour prediction of aircraft structural parts CNC machining has the following significance: [0003] (1) To carry out production capacity assessment, the manufacturing enterprise can calculate the time cost of product manufacturing according to the working hours of CNC machining, calculate the salary of workers according to the working hours, estimate the delivery date of products, and ensure the rationality of enterprise production; [0004] (2) Formulate the production plan of the product. For a new product, determining the production working hours only based on experience ma...
