The manufacturing requirements of milling cutters are high and difficult. In this paper, through the combination of years of practical processing experience and theory, it is necessary to reasonably select tool materials, geometric parameters, grinding wheels, etc. to make a high-quality milling cutter on a CNC tool grinder. Complete the data integration system between various modules. Through the simulation software, the correctness of the program and the motion track of the machine tool is confirmed, and the precision processing process is carried out to complete the automation, high speed, and intelligence of the processing tool.
CNC tool grinders are widely used in the processing of various structural shapes such as the peripheral surface, forming surface, and grooves of the processed parts. The primary structural parameters of the milling cutter are the number of teeth, helix angle, groove depth, rake angle, end tooth, peripheral tooth clearance, etc. . In the meantime, the spiral chip flute geometry is the most critical element of the tool geometry point of view. Whether the flute geometry is reasonable or not directly affects the tool life, smooth chip evacuation, and machining accuracy. Now CNC tool grinder grinding the spiral groove of the end mill has become the primary process, instead of the traditional forming milling groove. The primary elements of choosing a groove shape are the surface, groove depth, and rake angle of the rotating grinding wheel used for grinding the tool. Generally cut brittle materials or high hardness, the groove depth is shallower. For plastic materials, the groove depth is deeper. End mills are classified into right-angle end mills, ball end mills, and arc end mills according to the type of cutter head. Right-angle end milling cutters are used to machine the surrounding surfaces of grooves, spherical milling cutters are used for forming, profiling, etc., and ball end milling cutters are used to process surrounding surfaces with a corner R.
The five-axis sharpener is made in Switzerland, it uses the FANUC control system and the standard module software developed specifically for manufacturing tools-Quinto.
The control software FANUC used by the grinder is a high-tech solution for axis positioning, interpolation, and user interface. Quinto application software provides users with a simple and flexible interface for accessing the machine.
It has five axes: X-axis, Y-axis, Z-axis, A-axis, and C axis.
Quinto Standard Software
The geometric parameters and processing parameters are input in menu type, used for forwarding processing power, supported by the database, including tool processing, side head program, grinding wheel geometric parameters, etc.
