模具高速铣削技术加工的关键技术
1)刀具系统;
刀具系统是指构成刀具的系统结构,其中主要是指刀具材料、刀具结构和刀柄.刀具材料有较高的硬度和耐磨性、良好的强度和韧性、良好的耐热性和工艺性.目前,高速铣削中使用的刀具材料主要有金刚石、立方氮化棚、陶瓷刀具、硬质合金刀具和涂层刀具等.
刀具结构主要是整体和镶齿两种.镶齿刀具主要采用机夹机构,高速铣削刀具由于离心力的作用,会造成夹紧机构破坏和刀片甩掉,所以刀体夹紧机构必须有较高的强度、断裂韧性和刚度,保证安全可靠.
刀柄系统在高速铣削时,主要解决刚性不足,重复精度不稳定、离心力的影响、刀柄不方便快速换刀等问题.
2)机床系统;
机床系统是指实现高速铣削要素的结构保障系统,主要是保证高速切削速度的高速主轴系统和获得精确进给速度的快速进给系统.
高速主轴系统是高速铣削的关键之一.高速主轴系统应具有足够的刚度和高的回转精度;重量轻、结构紧凑,惯性小;良好的热稳定性;振动和噪声小;良好的冷却和润滑系统.
3) 模具CAD/CAE/CAM软件系统;
模 型构建(CAD)、分析(CAE)和制造(CAM)过程软件系统必须能够接受从其他系统传来的数据并处理这些数据,所以必须有一致、标准化的接口.目前, 模具加工最常用的接口标准是IGES(原始图形交换标准).高速铣削的关键在于CAD/CAM用的程序编制器能够自动调节铣床刀具的最佳加工方式.
4)CNC控制系统.
安 全CNC控制系统应具有快速数据处理能力和较高的功能化特征,以保证高速切削时具有良好的加工性能.高速铣削加工模具时对CNC控制系统的要求主要有以下 几点:(1)优良的进给控制功能;(2) 程序段循环时间短;(3)高的插补精度,为了保证高速下的插补精度,要有前馈和大数目超前程序段预处理功能,此外,还可以采用非均匀有理B样条插补、回冲 加速、平滑插补、钟形加速等轮廓控制技术;(4)接口数据处理网络,为了缩短数据处理时间,CNC控制器必须能通过“以太”网直接输送程序.

Die high-speed milling technology for processing the key technology
1) tool system;
Tool system is the structure constitutes a tool of the system,which mainly refers to tool material,tool and toolholder.Tool material has high hardness and wear resistance,good strength and toughness,good heat resistance and technics.At present,high-speed milling tool materials used in the main diamond,cubic nitride studio,ceramic cutting tools,carbide cutting tools,such as cutting tools and coatings.
The main tool is the overall structure and set of two teeth.Inlaid teeth mainly machine tool folder institutions,high-speed milling cutter role as a result of centrifugal force,this will result in destruction and blade clamping bodies off,so clamping cutter body must have a high strength,fracture toughness and rigidity to ensure the safe and reliable .
Handle system in the high-speed milling,the main settlement of less than rigid,repetitive precision of instability,the effects of centrifugal force,handle issues such as inconvenient for rapid tool change.
2) machine tool system;
Machine system is a means to achieve high-speed milling elements of the structure of security system,mainly to ensure that high-speed cutting speed,high-speed spindle system and access to accurate feedrate rapid feeding system.
High-speed spindle system is one of the keys to high-speed milling.High-speed spindle system should have sufficient rigidity and high precision rotary; light weight,compact structure,small inertia; good thermal stability; vibration and noise; good cooling and lubrication system.
3) Die CAD / CAE / CAM software system;
Model (CAD),analysis (CAE) and manufacturing (CAM) software system for the process must be able to receive from other systems and process data from these data,it is necessary to have a consistent,standardized interface.At present,the most commonly used mold interface standard is IGES (original graphics exchange standard).The key to high-speed milling CAD / CAM programming devices used to automatically adjust the best machine tool processing.
4) CNC control system.
CNC control system security should have the fast data processing capabilities and higher functional characteristics,in order to ensure high-speed cutting has a good processing performance.High-speed milling mold on the request of CNC control systems are mainly the following points:(1) a good feed control; (2) program segment short cycle time; (3) high interpolation accuracy,in order to ensure high-speed under the interpolation accuracy,should be the number of feed-forward and ahead of pre-processing program segment,in addition,can also be the use of non-uniform rational B-spline interpolation,to accelerate the return to red,smooth interpolation,speed up,such as bell-shaped contour control technologies; (4 ) interface data-processing networks,in order to shorten the data processing time,CNC controller must pass the "Ethernet" net direct delivery procedure.
