The flute grinding angle for the second pass Afs can be calculated using Eq 12 The second flute angle decreases as αS increases Thus the flute grinding angle meets the design requirements for the second flute angle Afs ¼ αE −α J þ ∆α ð12Þ With this method the center coordinates ½ OWEx OWEy are the coordinates of the end
·The profile of helical flutes has a great influence on properties of cutting tools This paper presents an automatic method of searching for a wheel position in flute grinding for a given shape of
·To solve this problem this paper presents a trajectory calculation method for grinding the flute of conical milling cutters Firstly the conical cutting edge line is deduced and the position of the wheel in the whole grinding process is calculated under the design requirements of the rake angle and the core radius
·Wheel position including wheel location and orientation in the flute grinding process of an end mill determines the ground flute s geometric parameters rake angle core radius and flute width Current technologies for calculating the wheel position to guarantee the three parameters accuracy are either time consuming or only applicable to the grinding
A novel algorithm was proposed to optimize the wheel s location and orientation for the flute grinding to achieve higher accuracy and efficiency and this method could be extended to more complex grinding operations with the requirement of high accuracy such as various section cutting edge resharpening Expand
·However a closed flute of a tool which is one style of flute may cause many problems if grinding it by one pass grinding wheel dressing to adapt to the change of flute parameters To solve the problem in closed flute grinding this paper proposes a two pass flute grinding based on the iteration method
