【摘要】：刀具作为机加工车间生产最主要的消耗品资源之一,在零部件制造成本中占有较大比例,能否有效的管理刀具对车间生产的效率和成本影响巨大。为此,本文以航空发动机数控加工车间为服务对象,综合应用信息编码、激光标刻以及数据库开发等技术,进行了刀具信息标识与刀具管理技术等研究。主要的研究工作如下:(1)应用刀具面分类和线分类方法进行刀具分类,进而构建刀具信息模型,然后采用刚性编码和柔性编码相结合的编码方式进行刀具信息编码,并设计了刀具信息编码软件。(2)以Data Matrix(DM)二维条码作为刀具管理系统中刀具信息载体,采用Advanced Encryption Standard(AES)加密算法,构建了目标刀具的DM二维码信息模型,并设计了DM二维码生成软件。(3)进行了刀具DM二维码直接激光标刻试验,获得了在硬质合金表面进行激光标刻DM二维码的参数选择规律,然后进行了DM二维码的可读性检验试验,揭示了油污、光线、残缺、识读距离等对激光标刻DM二维码识读性的影响,并给出了建议识读条件。(4)设计开发了基于B/S架构的网络化刀具管理数据库系统。其中,刀具信息主要包括刀具基本信息、刀具技术参数信息、刀具历史使用信息等。通过对刀具表面激光标刻DM二维码的读取,实现了对目标刀具的全寿命周期监控与管理。
[Abstract]:As one of the most important consumable resources in machining workshop, cutting tools account for a large proportion of the manufacturing cost of parts and components. Whether the tool can be effectively managed has a great impact on the efficiency and cost of workshop production.Therefore, this paper takes the aero-engine NC workshop as the service object, synthesizes the technology of information coding, laser marking and database development, carries on the tool information marking and tool management technology and so on.The main research work is as follows: (1) tool surface classification and line classification are applied to tool classification, then tool information model is constructed, and then tool information coding is carried out by combining rigid coding with flexible coding.The tool information coding software. 2) using Data Matrix Data bar code as the tool information carrier in the tool management system, and adopting the Advanced Encryption Standard AES-based encryption algorithm, the DM two dimensional code information model of the target cutter is constructed.The DM QR code generation software. 3) was designed to carry out the direct laser marking experiment of DM QR code for cutting tools. The parameter selection rule of DM QR code engraved on the surface of cemented carbide was obtained, and then the readability test of DM QR code was carried out.This paper reveals the influence of oil stain, light, incomplete, and reading distance on the reading ability of DM two-dimension code for laser marking, and gives the suggested reading condition. (4) A network tool management database system based on B / S architecture is designed and developed.Among them, tool information mainly includes tool basic information, tool technical parameter information, tool history information and so on.The whole life cycle monitoring and management of the target tool is realized by reading the DM 2 D code of laser marking on the tool surface.
