Problems solved by technology

In terms of calculating the man-hours of cutting materials, the calculation method of man-hour quotas still remains in the empirical estimation method, which relies on manual calculations, which has problems such as low work efficiency and error-prone
In addition, it is necessary to recalculate the cutting man-hours every time a production task is issued, and it is impossible to realize the process front-end, and the workload of the man-hour quota personnel is relatively large

Embodiment 1

[0090] Example 1: Calculation of man-hours for bar blanking

[0091] 1. After the manufacturing department receives the task of product development and transfer to production, it starts to prepare production information. The product specification is aluminum alloy with a diameter of 20mm.

[0092] 2. Fill in the blanking calculation parameters in the process card of the process baseline. The bar calculation parameters are filled in as shown in Table 1.

[0093] Table 1 Bar blanking calculation parameters

[0094]

[0095] 3. In the process baseline, prepare the blanking man-hour quota data of a single machining process card. The formula for calculating the working hours of the bar is:

[0096] Step man-hour = T 基 ×shape factor÷60

[0097] where T 基 It is determined by the two parameters of bar material diameter and material. T 基 =6. The shape factor of the bar stock is equal to 1. Therefore, the working time of the bar is: 0.1.

[0098] 4. After receiving the off...

[0107] Example 2: Calculation of man-hours for shearing and blanking

[0108] 1. After the manufacturing department receives the task of product development and transfer to production, it starts to prepare production information. The product specification is 777mm in length, 515mm in width and 5mm in thickness.

[0109] 2. Fill in the blanking calculation parameters in the process card of the process baseline. The sheet calculation parameters are filled in as shown in Table 1.

[0110] Table 3 Sheet blanking calculation parameters

[0112] 3. In the process baseline, prepare the blanking man-hour quota data of a single machining process card. The formula for calculating the man-hours of the shearing steps is:

[0113] Step man-hour = (T 基1 +T 基2 )×coarse and fine shearing coefficient×shearing method×area coefficient÷60

[0114] T 基1 and T 基2 It is jointly determined by the three parameters of the length, width and thickness of the blank, and the T 基1 =10....

Abstract

The invention discloses a baseline-based machining process blanking man-hour calculation method, and relates to the technical field of digital manufacturing. And after the manufacturing department receives a product development-to-production task, production information preparation is started, a product process baseline is established at the stage, and blanking man-hour data of a single machiningprocess card are compiled. And then, when a process file is synchronized in the manufacturing baseline management module, the blanking man-hour quota data are subjected to overturning calculation. According to the invention, the process base line and the manufacturing base line are introduced, modular management of the blanking man-hour quota of the machining process is realized, and the production efficiency is improved; on the basis, a traditional blanking man-hour quota calculation process is combined with an informatization technology, and the blanking man-hour is rapidly and accurately calculated by utilizing an informatization intelligent means.

Description

technical field [0001] The invention relates to the technical field of digital manufacturing, in particular to a baseline-based calculation method for blanking man-hours in a machining process. Background technique [0002] Working hours quota is an important basis for enterprises to formulate reasonable quotations and evaluate employee performance. The formulation of scientific and standardized working hour quotas can effectively mobilize the enthusiasm of workers and promote the improvement of workers' technical level; on the other hand, it can also improve the production efficiency of enterprises, maximize the production potential of enterprises, and increase the industry competition of enterprises force. [0003] For enterprises developing electronic equipment, the production of mechanical processing products has the characteristics of many varieties and small batches, that is, there are many varieties of products, small quantities and variable specifications. However,...
