Customizing Drop Downs/ Right Mouse Button Menu

Customize Drop Downs Menu allows you to:

Add or remove new drop down menus

Add or remove functions in a drop down menu

In the Menus list, right click and choose the Add drop down menu option Mastercam

automatically adds a new drop down menu, assigns a default name, and places the new drop down

menu at the bottom of the menu list

To add a function to a drop down menu, choose a Category from the list and drag and drop the function

to the drop down menu in the Menus list If the drop down menu is not expanded, the new function is

added as the last function Otherwise, it is inserted below the selected function on which it is dropped

To remove a single function from a drop down menu, expand the menu, select the function, and press

the Delete key To delete the entire menu, right click and choose Delete drop down menu.

Customize Right Mouse Button Menu allows you to:

Add, remove and rearrange functions and submenus

Adding or removing drop down menu functions is associative All references to the

modified drop down menu are also updated (for example, the modified drop down menu is

used as a submenu in other drop down menus) When you add or remove functions from

drop down menus and submenus, you immediately see the results in the current Mastercam

session

Example: Add Zoom Target to the Right mouse menu.

The default Right mouse menu looks as shown to the right.

Set the Stock amount to 0

Rough step sets to Percent of tool width (sets the amount of stock that gets remove during each

cutting pass as a percent of the tool width)

Backoff % is set to 10 (determines how far the tool will back away from the wall of the groove

before it retracts)

Set in the Second pass lead in the Exit Vector to

Angle = 90 and Length = 0.1

Note the tool collision warning and select yes to

continue writing the toolpath

Note that at the start of the finish pass the tool

collide with the stock We need to increase the

length of the Lead in, on the first pass, to start feed

in the part from above the stock

Change the Length to 0.5
