After design in fusion electronics,we can switch to 3D PCB in the command of "Switch/view 3D PCB"

Remind:This method just for single layer PCB board.

1 .Choice model

We need use "manufacture" function, so switch from "3D PCB" to "manufacture"

We can just show board and 1-copper. (Hidden another layer:16 copper(bottom copper),1 solder masker,16 soler masker, Packages(electronics components))

2. Setup

In this step ,we should tell the machine the stock size of material and the direction. More detail About Set up

3. Process in Fusion CAM

Now we need 4 steps to process our PCB boards

Step1: Milling the electrical interconnections path;
Step2:Drilling the hole;
Step3:First time Milling the profile of the PCB board;
Step4:Second time Milling the profile of the PCB board;

3.1 Step1: Milling the electrical interconnections path

In this step ,we need use "Milling-2D-Trace "command

Now we need setting

Tool & Feed&Speed
Geometry
Height
Pass

3.1.1 Tool & Feed&Speed

We can click "Tool/Select " to setting the tool

How to confirm the parameter of cutter?

Type: we need cut the copper on the surface ,so we choice "flat end mill"
Paramenter:We use the 7pin connector, the gap betweeen two pins is 2.54mm,after calculate,we find the space for electrical interconnections path is 1.01mm
- To avoid the overlap too mach,red path and blue path, we can choice the cutter small then 1mm, for example 0.8mm,0.6mm,0.4mm
- If too small, the cutter is easy to broken;
- Finial we choice 0.6mm flat end milling cutter

The following is how to setting tool parameter in software

Another parameter setting

Coolcant:because we just process thin copper and resin,so don't need use any thing ,just choice disabled. For plastic ,small copper,aluminum,we don't need coolant, but if we process steel and similar metal,we need coolant
Spindle Speed(The rotational speed of the spindle expressed in Rotations Per Minute (RPM)):Our machine's speed is 1000rpm(only one speed),so choice 1000rpm;
Surface Speed(The speed which the material moves past the cutting edge of the tool (SFM or m/min)):It would calculate by software according to cutter diameter and spindle speed: Surface speed =cutter diameter X spindle speed
Ramp Spindle Speed - The rotational speed of the spindle when performing ramp movementsSame as spindle speed ,because the machine just one speed
Cutting Feedrate - Feedrate used in regular cutting moves. Expressed as Inches/Min (IPM) or MM/MinAccording to experience,60mm/min is available
Feed per Tooth - The cutting feedrate expressed as the feed per tooth (FPT)It wpuld calculate by software automatic
Lead-In Feedrate - Feed used when leading in to a cutting move.
Lead-Out Feedrate - Feed used when leading out from a cutting move
Ramp Feedrate - Feed used when doing helical ramps into stock
Plunge Feedrate - Feed used when plunging into stock
Feed per Revolution - The plunge feedrate expressed as the feed per revolution

3.1.2 Geometry

Function define:Select any 3D Edge or Sketch to define the machining curve. In this case, we just choice the following 16 chains.

3.1.3 Height

Clearance HeightThe Clearance height is the first height the tool rapids to on its way to the start of the tool path.
Retract height: incremental offset from the Retract Height.
Feed height: incremental offset from the Feed Height.
Top height: incremental offset from the Top Height.
Bottom height: incremental offset from the Bottom Height.
Model top: incremental offset from the Model Top.
Model bottom: incremental offset from the Model Bottom.
Stock top: incremental offset from the Stock Top.
Stock bottom: incremental offset from the Stock Bottom.
Selected contour(s): incremental offset from a Contour selected on the model.
Selection: incremental offset from a Point (vertex), Edge or Face selected on the model.
Origin (absolute): absolute offset from the Origin that is defined in either the Setup or in Tool Orientation within the specific operation.

In our case ,parameter is the following:

3.1.4 Pass

In this case ,we choice Right (conventional milling)

3.1.5 Simulate

We can use "simulate" command to check if the NC program has any problem

3.1.6 Output NC program

If simulate is OK,we can use Create NC program and then output.

Remind:we need choice GBRL according to our machine

3.2 Step2: Drilling the hole

In this step ,we need use "Drilling "command

Reference from "3.1.1 Tool & Feed&Speed",we can choice drilling cutter "Φ0.8mm".

The Geometry of this step is the 15 holes we need process, choice it one by one. About height, reference 3.1.3 ,and choice one by one ,the following is for reference.

In this step, the method of Passs,Simulate,Output NC programis same with "3.1", so just reference "3.1.4Passs"," 3.1.5 Simulate", "3.1.6Output NC program"

3.3 Step3: Milling the profile

Ever time we can just cut the deep less than 1mm, but the thickness of our board is 1.5mm, so we need process two times(first 0.8mm, second 1.5mm) and output 2 NC programs.

In this step ,we need use "Milling/2D/2D Contour"command

Tool we choice 0.8mm flat end milling cutter. the feed and speed reference the following.

The Geometry just choice the profile of the PCB board.

The only different for first 2D Contour and second 2D Contour is the above "Bottom Height"
