Question
A block of length is machined by a slab milling cutter in diameter. The depth of cut and table feed are set at and , respectively. Considering the approach and the over travel of the cutter to be same, the minimum estimated machining time per pass is ________ minutes.
Correct answer
11.95 to 12.05
Solution
Given:
Length of block () =
Diameter of cutter () =
Depth of cut () =
Table feed () = In slab milling, the approach distance () is given by:
Given that approach and over travel () are the same:
Total length of travel () =
Minimum estimated machining time () =
Length of block () =
Diameter of cutter () =
Depth of cut () =
Table feed () = In slab milling, the approach distance () is given by:
Given that approach and over travel () are the same:
Total length of travel () =
Minimum estimated machining time () =
