An aluminum block of length 50 mm and width 70 mm is being milled using a slab milling cutter with 50 mm diameter. The feed of the table is 15 mm/min. The milling cutter rotates at 60 RPM in clockwise direction and width of cut is equal to the width of the workpiece. Draw a neat sketchof the milling operation describing aboveconditions. The

Turning, drilling, and milling are just a few of the most common machining processes. They''ve been around for many, many years. Fortunately, with the development of CNC, machining has improved immensely. While conventional machining still has its purpose in manufacturing, CNC machining .
Sep 23, 2019· In orthogonal type of cutting, the surface finish obtained is very poor when compared to oblique cutting which gives a fairly good surface finish. Orthogonal type of cutting is used in grooving, parting, slotting, pipe cutting etc while oblique cutting is used almost in all industrial cutting, used in drilling, grinding, milling etc.
Speed, stated in surface feet per minute, (sfpm) is the peripheral speed at the cutting edge. To convert rpm into sfpm, use the following: V=( *D1*N s)/12 (converting D to ft.). This applies to milling, drilling turning and all rotary operations. Feed per revolution in turning ( and drilling ) is a geared feed driven from the main spindle. f r ...

workpiece surface being machined • Cutters may have straight or helical teeth, resulting in orthogonal or oblique cutting action, respectively (helical teeth lower tooth load, tool forces, chatter) • In conventional (up milling) the maximum chip thickness is at the end of the
Jul 16, 2016· After calibrating the cutting force coefficients with performing straight milling tests, two typical curved surfaces were investigated. The one was a circular curved surface with constant radial depth of cut, while the other was a Bezier curved surface with variable radial depth of cut.
It is shown that the milling force coefficients for all force components and cutter geometrical designs can be predicted from an orthogonal cutting data base and the generic oblique cutting analysis for use in the predictive mechanistic milling models.

CHARACTERISTICS OF SURFACE INTEGRITY GENERATED BY OBLIQUE MACHINING OF STEEL PARTS Wit Grzesik S u m m a r y In this study the surface integrity produced by oblique turning of a C45 carbon steel was quantified by means of 2D and 3D surface roughness parameters, strainhardening effects and associated residual stresses.
orthogonal and oblique cutting. The use of single edged tools in sloped cutting provides a favorable surface finish characteristic. Was elaborated model of oblique cutting to predict the cutting forces, the chip flow direction, the contact length between the chip .
In this study, sugar maple (Acer saccharum Marsh.), northern red oak (Quercus rubra L.), and eastern white pine (Pinus strobus L.) were surfaced by oblique cutting and face milling, while paper birch (Betula papyrifera Marsh.) was face milled. Cell damage was considerably higher in face milling than in oblique .
An oblique ion milling simulation method is proposed in which etching and redeposition at the pattern side wall are taken into account. The effective etching rate at the pattern side wall is determined as the difference between the etching rate given by the angular dependency and the redeposition rate.
Lin and Lin [13] established a thermoelastic±plastic ®nite element model for oblique cutting under a constant low cutting speed condition, in which they investigated the temperature effect on such physical properties as cutting force, speci®c cutting energy and stress distribution on the chip surface during the oblique cutting process.
