According to the end geometry:
Flat bottom end milling cutter
Flat bottom R Angle end milling cutter
Ball end milling cutter
Indexable Mosaic endmill
The basic geometric structure of the cutting tool
The geometric accuracy of the cutting tool
For finishing cutting tools, the cutting edge must have good profile accuracy.
outline several possible deviation of cutting tool
As the grinding process is not accurate enough, irregular broken surface appears on the edge.
Radius deviation due to inaccurate grinding process
If the workpiece precision requirements are very high, should be purchased from a tool manufacturer with standard certification.
Four, to ensure that the tool radial runout error minimum
Under the premise that the maximum overhang length of the tool handle and the tool system does not exceed the specified value, the radial run-out error of the tool must be detected at the tool handle and cutting edge respectively in order to make the spindle run accurately. If the radial runout error is too large it will lead to severe vibration of the spindle.
How to choose the right cutting tool
(1) Analyze specific processing conditions, such as spindle and machine tool performance, tool clamping system, lubrication, etc.;
(2) Analyze the material characteristics of the workpiece;
(3) Analyze machining surface quality, machining precision requirements, cost, etc.;
(4) Considering various factors comprehensively, make the optimal choice.
Vi. Calculation method of machining parameters of high-speed cutting
Three important formulas
Several important terms and machining parameters in high-speed cutting process
1. Cutting speed Vc
Definition of cutting speed :Vc=N* P *Deff/1000
Vc refers to the appropriate cutting speed value suitable for high speed machining of some workpiece material in the case of a specific tool, it refers to the linear speed of the tool. How to set the Vc value of cutting speed correctly:
