About Construction Plane (Cplane)

The Cplane is a flat, two dimensional plane on which you create geometry and that can be defined

anywhere in three dimensional space

There are 8 predefined construction planes in Mastercam They are the same as the Graphic Views

To set the desired Cplane, choose Plane, from the Status Bar, and select the desired Cplane.

You can also work in a 3D plane that allows you to draw in unrestricted 3D space You can use the

3D plane while creating geometry that can be related with existing geometry For example, if you

create a line knowing the endpoints or trimming entities up to other entities

To set the 3D plane, choose 3D from the Status Bar.

TOOLPATH CREATION

STEP 8:

DEFINE THE STOCK.

Select the Top View from the view toolbar to see the part from the top.

Machine type

Mill

Select MILL 4 AXIS HMC.MMD.

To display the Toolpaths Manager

press Alt + O.

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

Properties.

Select theplus

Select Stock setup.

Selectstock setup

Make sure that you have the same setting in the Bounding Box as

shown to the right

The system automatically establishes the stock size by finding the

extents of the selected geometry

Select the OK button to exit.

The Stock setting should look as shown below

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)

Page 1 20

X³ TOMBSTONE PROJECT

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.

Select the Isometric View from the view toolbar to see the stock.

STEP 9:

FACE THE USER DEFINED PLANE (Triangle View).

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

tool plane represents the CNC machine’s coordinate system (XY axis and origin)

9.1 Change both Cplane and Tplane to Triangle View

Select WCS in the Status Bar.

Select View Manager.

Select the Triangle View

Click on Set your current tool plane

and origin to the selected view

button

Click on Set your current

construction plane and origin to the

selected view button.

Check Enable origin to set the new origin for the plane at the lower left corner based on the view

coordinates

Change the Work Offset # to 0

To set different work offset

for each Tplane, Mastercam

requires that you specify work

offsets in a generic format

Offsets are identified starting

with the number zero and

incremented by one for each

successive offset For

example, in Fanuc controls,

0=G54, 1=G55,

The View Manager will look as

shown to the right

Select the OK button to exit the View Manager name.
