EdgeCAM Manufacture - User Guide

Entering Manufacture Mode

EdgeCAM starts up in Design mode, as it assumes that you want to begin by

creating a part. If you have already created a part, or have loaded an existing

part, you will now want to start the machining process.

To use the EdgeCAM system, you should be experienced in CAD/CAM

methods and the appropriate equipment and terminology. You also need to

have some experience of the Microsoft™ Windows NT™ graphical user

environments.

Most of the commands you require are not present in Design mode (to make

the number of commands available to you more manageable). To access the

commands for machining a part, you must enter the Manufacture mode.

Select Manufacture (Options menu) or press the Manufacture button to

switch into Manufacture mode.

If you need to switch back into Design mode at any time, click on the Design

button or select Design (Options menu).

If this is the first time you have entered Manufacture mode since starting

EdgeCAM, you are prompted for details on what type of machining you want

to use. This information defines a new “machining sequence” or machining

worksession. You also specify which Code Generator file you want to use. A

Code Generator provides appropriate manufacturing commands and contains

the data on converting an EdgeCAM machining sequence into CNC code for

a specific machine tool type.

You may enter Manufacture mode with a new executable file (for example, a

PDI) or a new Code Generator file. If you do, you are prompted to enter the

text for the machine - specific commands that appear under the M - Functions

menu.

About Creating Wire Toolpaths

Before you try to create wire toolpaths, you should already have created a

Wire Profile. Whichever method you used to create the profile, simply select

the command Machine Design (Cycles menu) . This command uses

whatever information is stored in the profile to generate the appropriate

toolpaths. Also see Creating the Design Intent .

Manufacturing Basics

Browsing the Instruction List

The Instruction List is, simply, the list of all machining commands for the

current part. Each time a new machining command is used on the part, it is

added to the bottom of the list of the current machining sequence.

Commands that cannot be converted into CNC code (for example, viewing

and editing commands) do not appear on the list.

The browser on the left of the screen shows all machining sequences and

instructions associated with the current part.

You can also view the EdgeCAM Instruction list associated with a job from

within the Job Manager or the web-based Job Reports. If an associated

instruction list exists for a particular job, the instructions will be displayed on

the Instructions tab of the Job Manager or through a link on the job reports

page.

The icon for the current machining sequence is shown with a green

background.Note that the machine sequence description is followed by the

code generator file (‘Machine Tool’ in dialogs defining the sequence) used by

the sequence. ‘Sequence 1’ is used by default if you do not specify a

description.

By default, as the mouse is moved over an instruction in the browser window,

the relevant toolpath is automatically highlighted in the graphics area.

Uncheck the Highlight Instructions option on the Toolpaths tab of the

Preferences (Options menu) dialog to disable this functionality.

Clicking on a plus sign expands the view to show all instructions under that

machining sequence, including toolchange descriptions with turret position.

To collapse part of the view, click on the minus sign.

You can use the mouse to drag instructions to a new position in the list if

necessary. You can also copy instructions to a new position in the list by

holding down the 'Ctrl' key while dragging the instructions.
