1 Introduction
Production tools (better known as moulds) are an essential element in the manufacturing of wide consumption goods.The design and the fabrication of moulds are a very long and expensive step in the development of a new product.For such reason, any effort improving moulds’ manufacturing helps to reduce times and costs.
Nowadays, modern CAD/CAM technologies and five-axis high-speed milling allow:
1、導(dǎo)言
生產(chǎn)工具（稱為模具）是大部分產(chǎn)品制造的一個(gè)重要組成部分。在開(kāi)發(fā)新產(chǎn)品過(guò)程中，設(shè)計(jì)和制造模具是一個(gè)非常漫長(zhǎng)和昂貴的一步。正是這樣的原因，任何努力提高模具的制造有助于降低成本和時(shí)間。
如今，現(xiàn)代的CAD / CAM技術(shù)及5軸高速銑削允許：
