TUTORIAL #11 SELECT THE MACHINE AND SET UP THE STOCK

STEP 8: SELECT THE MACHINE AND SET UP THE STOCK

In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition

is a model of your machines capabilities and features. It acts like a template for setting up your

machine. The machine definition ties together three main components: The schematic model of your

machines components, the control definition that models your control capabilities, and the post

processor that will generate the required machine code (G-code). For a Mill Level 1 exercise (2D

toolpaths) we need just a basic machine definition.

To display the Operations Manager press Alt + O.


Machine type

Mill.

Default.

Select the plus sign in front of Properties in the Toolpaths Manager to expand the Toolpaths

Group Properties.

NOTE: For the purpose of this tutorial, we will be using the Default mill machine.


SELECT THE MACHINE AND SET UP THE STOCK TUTORIAL #11

Select Tool Settings to set the tool parameters.

Figure: 8.0.1

Change the parameters to match Figure: 8.0.2.

Figure: 8.0.2

machine tool requires a number for a program

name.

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 Stock setup tab to define the stock.

Set the stock shape to Rectangular if needed and enter the stock dimensions as shown in

Figure: 8.0.3.

Figure: 8.0.3

Select the OK button to exit Machine Group Properties.

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


The Stock Origin values adjust the positioning of the

stock, ensuring that you have equal amount of extra

stock around the finished part.

Display options allow you to set the stock as

Wireframe and to fit the stock to the screen. (Fit

Screen)

NOTE: The stock model that you create can be displayed with the part geometry when

viewing the file or the toolpaths, during backplot, or while verifying toolpaths. In the

graphics, the plus shows you where the stock origin is. The default position is the middle of

the stock. Click on the corner of the part to set it as the stock origin.



The stock model will appear as shown.

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

NOTE: The stock is not geometry and can not be selected.


TUTORIAL #11 MACHINE THE TWO STEPS USING OPEN CONTOUR TOOLPATH

STEP 9: MACHINE THE TWO STEPS USING OPEN CONTOUR TOOLPATH

Contour toolpaths remove the material along a path defined by a chain of curves. Contour toolpaths

only follows a chain; they do not clean out an enclosed area.

Toolpath Preview:

9.1 Chain selection

A chain of entities consists of one or more entities linked together in order and direction. The distance

between the endpoints of two consecutive entities of the chain has to be equal or less than the

chaining tolerance (0.0001"). In an open chain, the start point is placed at the end of the chain closest

to the selection point and the chain direction points to the opposite end of the chain. See the User

Notes chapter for more information on chaining.

Toolpaths

Contour.

If a prompt appears to Enter new NC name, select the OK button to accept the default.


MACHINE THE TWO STEPS USING OPEN CONTOUR TOOLPATH TUTORIAL #11

Enable the Chain button in the chaining dialog box to be able to select just the outside

contour.

Select the first chain as shown in Figure: 9.1.1.

Figure: 9.1.1

NOTE: The direction of the chain determines the cutter compensation side (Left or Right) to

orient the tool on the proper side of the geometry. For our example be sure to chain the

contour in a CCW direction. Otherwise, select the Reverse button.



To be able to machine both contours in one operation select the second chain as shown

in Figure: 9.1.2.

In the Toolpath Type page, the Contour icon will be selected.

9.2 Select a 3/4" Flat Endmill from the library and set the Tool parameters

Select Tool from the Tree view list.

Click on the Select library tool button.

To be able to see all the tools from the library disable Filter Active.

NOTE: Mastercam updates the pages as you modify them and then marks them, in the Tree

view list, with a green check mark. Pages that are not changed are marked with a red circle

and slash.



Scroll down and select the 3/4" Flat Endmill as shown.

Select the tool in the Tool Selection page and then select the OK button to exit.

Make all the necessary changes as shown in Figure: 9.2.1.

Figure: 9.2.1

The Feed rate, Plunge rate, Retract rate and Spindle speed are roughly based on the part material Aluminum and HSS

tooling. You may change these values as per your part material and tools.

In the Comment field enter a comment to help identify the toolpath in the Toolpaths/Operations Manager such as the

one shown above.



9.3 Set the Cut Parameters

From the Tree view list, select Cut Parameters and make the changes as shown in Figure:

9.3.1.

Figure: 9.3.1

Compensation type set to Computer allows Mastercam to compensate the toolpath based on the tool diameter and

does not output G41/G42 in the code.

Compensation direction set to Right compensates the toolpath to the right of the chain based on the chaining

direction. See the Figure: 9.3.2.

Roll cutter around corners set to Sharp inserts arc moves around corners in the toolpath. The radius of the arc moves

is equal with the radius of the tool.

Infinite look ahead prevents the toolpath from crossing itself (fish tail).



Figure: 9.3.2

9.4 Set the Lead In/Out

From the Tree view list, select Lead in/out and change the parameters as shown.

Make sure that you disable the Entry and the Exit options and enable Adjust start/end of

contour as shown in Figure: 9.4.1.

Figure: 9.4.1

Lead In/Out allows you to select a combination of a Line and an Arc at the beginning and/or end of the contour

toolpath for a smooth entry/exit while cutting the part.

Adjust start/end of contour moves the starting/ending position in open contours by adding (Extend) or removing

(Shorten) the specified length.



9.5 Set the Linking Parameters

From the Tree view list, select Linking Parameters and change the parameters as shown

Figure: 9.5.1.

Figure: 9.5.1

Select the OK button to exit the contour parameters.


BACKPLOT THE TOOLPATHS TUTORIAL #11

PART SETUP:

SETUP SHEET:



STEP 8: SELECT THE MACHINE AND SET UP THE STOCK

Step Preview:

In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition

is a model of your machine tool's capabilities and features and acts like a template for setting up

machining jobs. The machine definition ties together three main components: the schematic model of

your machine tool’s components, the control definition that models your control unit’s capabilities and

the post processor that will generate the required machine code (G-code). For a Lathe exercise (2D

toolpaths) we need just a basic machine definition.

To display the Operations Manager press Alt + O.


Machine type
