Objectives:

The Student will design a 3-dimensional drawing by:

Creating the 2D geometry in the Right Side view.Creating the 3D geometry using translate command.Creating circles knowing the diameter and the center location.Changing the view of the part for better visualisation.

The Student will create a 2-dimensional milling toolpath in different Tplanes consisting of:

Using View Manager to select the Tplane for each face.Create an operation for each face using the same work offset (G54).Facing one flat surfaces.Facing the other two flat surfaces using Transform-Rotate toolpath.Drilling the two holes.Removing the material inside of one groove using contour toolpath.Machine the second groove using Transform-Rotate toolpath.

The Student will check the toolpath using Mastercams Verify verification module by:

Defining a 3-dimensional block, the size of the workpiece.Running the Verify function to machine the part on the screen.

GEOMETRY CREATIONSTEP 1: CREATE THE 2D GEOMETRY IN THE RIGHT SIDE VIEW

Option 1 The geometry file, Tutorial4_geometry.zip, can be downloaded fromwww.emastercam.com/filesThe finish part, Tutorial4_finish.zip including the toolpaths, is also provided on the same locationwww.emastercam.com/files

Option 2 -Create the geometry using the following instructions:

Create the 2D profile in the Right side view:

Create/Arc/ Create Circle Center Point and set parameters to:Diameter = 5.0;

The tool plane (Tplane) is the plane in which the tool approaches and machines the part. TheTplane represents the CNC machines coordinate system (XY axis and origin). This is the cuttingplane for a toolpath, typically normal to the tool axisThe Rotary axis for our part is A-axis. The axis orientation for different views should look as shownin the following picture.

Compare the planes axis orientation when rotating the part about B axis. (horizontal machiningcenters).
