Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0030] Step A: Collect product manufacturing information through the production execution system (as attached figure 1 ), product manufacturing information includes fiber material consumption, resin material consumption, auxiliary material consumption, production team situation, production cycle and speed, production equipment information, production energy consumption, product model and parameters, output, scrap rate data information. This information can be verified by theoretical data, and can also be continuously verified and calibrated through long-term collection of production data, so as to reduce the error between the collected information and the actual information, and avoid errors caused by accidental events.

[0031] Step B: Collect th...

Abstract

The invention belongs to the technical field of composite material manufacturing, and relates to a cost calculation and control system in a high molecular material preparation process, in particular to a cost calculation and monitoring system based on prepregs in a technological manufacturing process. According to a given prepreg cost calculation mode, a mode of including manufacturing direct expense allocation of direct labor, equipment depreciation, manufacturing power consumption and the like in product manufacturing cost in conventional product cost calculation is abandoned; and based on an actual manufacturing process and a manufacturing status, a manufacturing execution system (MES) is adopted for collecting fiber material consumption, resin material consumption, auxiliary material consumption, manufacturing team or group states, manufacturing cycle and speed, manufacturing equipment information, manufacturing energy consumption, product types and parameters, yield and rejectionrate data information, and expenses directly related to manufacturing in manufacturing expenses are stripped out to the maximum extent, so that accurate calculation of the product manufacturing cost is realized and the manufacturing cost fluctuation states of products in different manufacturing conditions can be accurately reflected.

Description

technical field [0001] The invention belongs to the technical field of composite material manufacturing, and relates to a cost calculation and control system in the polymer material preparation process, in particular to a cost calculation and monitoring system based on prepreg in the process of manufacturing process. Background technique [0002] Prepreg is a composite material made of fibers, resins and other materials, which are processed by coating, hot pressing, cooling, film covering, coiling and other processes. Because prepregs can be made into composite structural parts by autoclave process, molding process, etc., and because its operation is simpler and more convenient than directly making parts from resin and fiber, fiber prepregs are widely used in various fields. Composite products. However, due to the complex production process of prepreg, many influencing factors, and sensitivity to environmental, artificial and other factors, it is difficult to calculate the ...
