Normal > two-phase makes milling plane is less than bottom to turn when receiving circular arc radius, intersect the situation that the circumstance of milling plane compares afore-mentioned parallel milling faces wants a few more complex, because its differ △ H,be calm value no longer, however variable. Generally speaking, fall when the state of affairs with the R is lesser and very little also included angle between two plane, original intent process designing is being pressed to machine inside treatment allow poor limits also is possible. But when R the case with two planar bigger and bigger also included angle falls, if do not undertake proper deflection is handled, be like graph 1a with respect to meeting generation in that way result, treatment hind keeps a data, design of short of hardware asks to the design of outline appearance. Be like the deflection of parallel milling face that puts forward above simple basis quantity of formulary computation deflection, only translation motion contrail, if undertaking process designing is machined, its can produce the case that graph 1b place shows as a result, much mill goes a material and cause spare parts outline to be hurt by mill, short of designs a requirement. Graph 1 intersect rank difference is less than milling face turn receive circular arc radius to be opposite afore-mentioned circumstances, if the graph shows method processing 2 times,can use. In the graph 2 in, we set inferior planar N to be XOY plane, building opposite coordinate is. The rank difference that sets two-phase to hand in plane to be nodded in the either on linear outline is; Radius of circular arc of blade of milling cutter bottom is the requirement in R(and hardware design consistent) ; Come to be worth with R from 0 change equal when (at that time need not deflection) linear length is; The P moving a point on the contrail that deflection motion makes when actual process designing is in the coordinate when rank difference is (X, y) . Normal > from the graph 2 in can see, give the linear outline AB that the design sets for treatment, milling cutter must press the P(X that move a point, the contrail of Y) moves. Graph Normal > by Normal > gets Normal > , normal > gets Normal > enters era Normal TEXT-INDENT of 5pt"> : 21pt; Mso-char-indent-count: 2. 0; Mso-char-indent-size: 10.
5pt"> must move bit of P(X namely, the athletic contrail of Y) is of of of accordingly, in be being fastened relative to coordinate in this, the contrail of actual deflection motion of cutting tool is ellipse of a standard, the rank difference that its grow an axis to make milling range for two-phase comes to be spent with the line end length when R of radius of bottom circular arc is equal from 0 change, its are short the numerical value that the axis is R of radius of bottom circular arc. To this athletic contrail can use one ellipse to approach processing point-blank, implementation machines a requirement. CNC Milling
