CHUCK INDEXING TUTORIAL

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 Mastercam’s 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

Otherwise follow next step

Set the construction plane to Top Plane.

Select Mill 4 AXIS VMC.MMD

Page 4 7

Select the plus in front of Properties to expand the Toolpaths Group Properties.

Select the plus

Select the Stock setup.

Select Stock setup

The stock shape should be set to

Cylinder.

Enable X Axis

Enter the Diameter and Length values

of the stock size

Enable Display stock as Wireframe

and enable Fit Screen to the stock.

The Stock Origin values adjust the

positioning of the stock, ensuring

that you have equal amount of

extra stock around the finish part

Display options allows you to set

the stock as Wireframe and to fit

the stock to the screen.(Fit

Screen)

Select the Tool Settings tab to set the tool parameters and the part material.

Change the parameters to match the following screenshot

Assign tool numbers sequentially

allows you to overwrite the tool

number from the library with the

next available tool number (First

operationtool number 1;

Second operationtool number 2,

etc)

Warn of duplicate tool numbers

allows you to get a warning if you

enter two tools with the same

number

Override defaults with modal

values enables the system to keep

the values that you enter

Feed Calculation set From tool uses

feed rate, plunge rate, retract rate

and spindle speed from the tool

definition

Select the OK button to exit Toolpath Group Properties.

STEP 6: FACE THE FLAT SURFACE AT 165 DEGREES ANGLE.

6.1 About Tool Planes

The tool plane (Tplane) is the plane in which the tool approaches and machines the part The

Tplane represents the CNC machine’s coordinate system (XY axis and origin) This is the cutting

plane for a toolpath, typically normal to the tool axis

The Rotary axis for our part is A axis The axis orientation for different views should look as shown

in the following picture

Compare the planes axis orientation when rotating the part about B axis (horizontal machining

centers)
