CAM 2.5 axis and three axis.

00:05

After completing this lecture, you'll be able to understand C A milling and fusion.

00:10

Describe the need for a tool library,

00:12

describe tool path creation and validation and identify

00:14

key steps in the C A process.

00:17

First, what is CAM

00:19

CAM stands for computer

00:20

aided manufacturing.

00:22

Cam is a tool used to help program CNC machines to perform complex operations.

00:27

Cam can be used to program CNC mills, lathes, water jet machines,

00:31

laser and plasma cutters, 3D printers and more

00:34

C

00:34

tools are available in the manufacturing workspace in fusion.

00:39

So what is the CAM workflow

00:41

in the manufacture workspace infusion?

00:43

There are a few key elements to workflow for cam milling.

00:47

These are the basic steps required.

00:48

First, a tool library.

00:50

This is a digital library used to replicate physical tools.

00:54

Next is the setup.

00:55

These are critical properties such as which machine is

00:58

being used where the coordinate system is located.

01:00

And how big the stock is.

01:02

The tool path is the actual path A tool will take to remove material from stock

01:07

simulate will validate tool pass effective removal of material.

01:11

The NC program will compile things such as machine post processor general settings

01:16

tool pass to include as well as things like program number and comment.

01:20

A setup sheet is a document that's created to convey

01:22

information about a program such as a W CS location,

01:26

the required tools and machine time.

01:28

And the G code is the last step of the process which is our machine readable code.

01:33

This is generated by converting our tool pa and fusion

01:36

to a set of instructions for a specific machine.

01:40

The tool library is a digital representation of

01:42

physical tools that will be used to machine apart

01:45

data about the tool is stored and selected during tool pa creation

01:49

data contained in a tool library includes things

01:51

like tool type size feed rate and number.

01:55

The tool data must match a physical tool

01:57

being used to avoid potential collisions and incorrect parts

02:00

and CNC machines will reference tool numbers to retrieve tools from a tool changer.

02:05

During operation,

02:07

the setup will define a single machining orientation on AC NC machine

02:12

setups contain data about the operation type,

02:14

the machine to be used the work coordinate

02:16

system stock and general post processor settings.

02:20

A new setup will be created each time you want

02:22

to change the orientation of the part on AC NC mill

02:26

tool path creation

02:28

tool paths are routines used to define tool motion based on geometry.

02:32

A 2.5 axis tool pass generally require the selection of geometry.

02:37

This is done by directly selecting faces and contours

02:41

through axis tool pas are generally

02:42

considered model aware and only require selections

02:45

to help limit or focus a tool path on a specified area.

02:50

Tool pa settings include what a machine, how deep to cut and how to enter or exit a cut

02:56

tool, pa validation

02:58

tool

02:59

validation is critical before any program is used on AC NC. Machine

03:03

tools

03:03

can be validated by using in process stock which displays a

03:06

generated preview of the model after the tool path has been run

03:10

simulation and machine simulation are used to learn more about the tool path

03:14

simulations show if too much material has been removed.

03:17

If a collision has happened or if material has been left behind

03:21

simulations are animations that allow you to

03:23

watch a sped up version of the machining

03:27

to about documentation

03:29

tool pa documentation is the last step before setting up

03:32

and testing a set of tool pas on a machine

03:34

and see programs are containers of information about which machine to use,

03:38

which settings for that machine and which tool paths are gonna be posted.

03:41

Posting a tool pa is a method of converting the

03:44

created tool pas in cam to code a machine can understand

03:48

and setup sheets are also created from NC

03:50

programs and provide a machine operator critical setup information

03:54

to ensure things like proper stock is used.

03:56

The tools are selected properly and the orientation is correct.

04:01

In conclusion,

04:02

cam is used to create a digital tool library and tool pass to control tool,

04:06

motion to manufacture parts,

04:08

tool about definitions in cam are converted to

04:10

machine readable code for a specified machine.

04:13

Documentation is created to provide machine operators.

04:17

The instructions needed to set up a new set of tool paths.

04:20

Invalidation is used to verify tool pas before any physical parts are made.
