Defining a Plane in an APT programming:

                            In an apt programming defining a plane in a space can be done by several methods, The apt programming for defining a plane is explained in this blog. the Gcode associated with the planes are G17, G18 and G19 which represents the XY, YZ and the ZX  planar coordinates. Intersection of these XY,YZ and ZX Planes passing through a point is called origin.
                           Planes are used in the CNC programming for defining a bottom of a part or used as a part surface or to define a safety approach and retract of the cutting tool. In CNC programming software's like CATIA V4, the Plane creation plays a major role for selecting the part surface.

Plane by three points in the space:
          Any three point in space can be joined to form a plane, for example, its like placing a plate on the three hinge points which keeps the plate without falling down. with one point and two hinge points we cannot balance a plate, so thus minimum 3 points are mandatory to create the plane.



Aptsource Code:
PL1=PLANE/P1,P2,P3











------------------------------------------------------------------------------------------------------------

Plane Parallel to other plane:
Plane can be created parallel to the another plane with the given distance. plane can be drawn parallel to XY, YZ or ZX plane at the origin. Also the plane can be drawn parallel to the planes created from the points, lines or the surfaces of the part. the Aptsource for the parallel plane can be written as shown below.



Aptsource Code:
PL1=PLANE/0,0,1,5 (0,0,1 is the I,J and K value)

PL2 may be defined as a plane parallel to PL1,

PL2=PLANE/PARALEL,PL1, ZLARGE, 10







------------------------------------------------------------------------------------------------------------
Similarly we can create a plane in the space in different methods, Creating a Plane by Two lines, creating a plane perpendicular to the other plane,
                            In CNC Programming the Planes are used in many ways, like selecting a bottom for toolpath, intersecting the part to know the sectional views of the part. the planes play a major role in defining the layers in the space. we can define 256 layers which uses the planes to define. the sketcher in an programming software work with the planes. when you select a plane in a sketcher then it becomes 2 dimensional with X, Y axis active in any Z level space.


enjoy learning Apt programming and cnc programming.
