大连数控加工是在数控机床上进行零件加工的一种工艺步骤，数控机床加工与传统机床加工的工艺规程从总体上说是一致的，但也产生了显著的变动。用数字信息节造零件和刀具位移的机械加工步骤，它是解决零件种类多变、批量幼、状态复杂、精度高档问题和实现高效化和自动化加工的有效蹊径。

数控机床一路头就选定拥有复杂型面的飞机零件作为加工对象，解决通常的加工步骤难以解决的关键。数控加工的最大特点是用穿孔带（或磁带）节造机床进行自动加工。由于飞机、火箭和发起机零件各有分歧的特点：飞机和火箭的零、构件尺寸大、型面复杂
；发起机零、构件尺寸幼、精度高。

Dalian CNC machining is a process method for machining parts on CNC machine tools. The process specifications for CNC machine tool machining and traditional machine tool machining are generally consistent, but there have also been significant changes. The mechanical processing method that uses digital information to control the displacement of parts and cutting tools is an effective way to solve problems such as variable part varieties, small batch sizes, complex shapes, high precision, and achieve efficient and automated processing.

From the beginning, CNC machine tools select aircraft parts with complex profiles as the machining objects, solving the key problems that ordinary machining methods are difficult to solve. The biggest feature of CNC machining is the use of perforated tape (or magnetic tape) to control the machine tool for automatic machining. Due to the different characteristics of aircraft, rockets, and engine components: large component sizes and complex profiles of aircraft and rockets; Engine components have small dimensions and high precision.
