Our company is the production roll forming machine.
1. INTRODUCTION
At present, many CAD / CAM software package provides automatic programming function, the software interface in the programming process planning tips related issues, such as tool selection, processing, path planning, such as cutting the amount of settings, as long as the programmers to set up a the relevant parameters can be automatically generated NC program and transferred to CNC machine tools to complete the processing.
Therefore, the NC machining tool selection and cutting parameters to determine the status of human-computer interaction in the complete, this machine with the general in sharp contrast, it also requires the programmer to grasp the cutting tool of choice and the basic principles in the programming to take full account of the characteristics of CNC machining can be the right choice and a cutting blade.
2. Processing tool offering several types of commonly used and characteristics of
CNC Machining CNC machine tool must adapt to high-speed, efficient, and the characteristics of a high degree of automation in general should include generic tools, knife handle and a small amount of general-purpose dedicated connection handle. Handle tool to connect and power head mounted on a machine, it has become standardized and serialized.
2.1 Classification of CNC tool There are many ways
a. According to the tool structure can be divided into
(1) monolithic;
(2) mosaic, using welding or machine clip-on connectivity, the folder-type machine can be divided into non-transposition and transposition of the two;
(3) a special type, such as composite tools, such as damping-style tool.
b. According to the manufacturer of the material used in cutting tools can be divided into:
(1) high-speed steel cutting tools;
(2) Carbide Tools;
(3) Diamond tools;
(4) other material tools, such as cubic boron nitride cutting tools, ceramic cutting tools and so on.
c. From the cutting process can be divided into:
(1) turning tools, particularly round hole, thread, cutting knives, etc.;
(2) drilling tools, including drills, reamers, taps, etc.;
(3) boring tool;
(4), such as milling cutter.
CNC machine tools in order to adapt to the tool durable, stable, easy to transfer, exchange, etc. In recent years, machine clip-on tool to be turning a wide range of applications, in the number of digital tools to achieve the entire 30 percent of a 40% metal removal accounted for 80% ~ 90%.
2.2 CNC machine tools and common tool used in the comparison tool, there are many different requirements, mainly has the following characteristics:
(1) rigid good (especially the roughing cutter) and high precision, small vibration and thermal deformation; interchangeability, and ease of rapid tool change;
(2) high life expectancy, stable cutting performance and reliable;
(3) to facilitate adjustment of the size of the tool to reduce tool change time to adjust;
