# Creating a work piece

each point represents the origin for X,Y,Z 0,0,0 of the equipment

---

# Creating a work piece

First click the botton part of the arrow and choose the plane in order to fix the Z plane.
---

# Creating a work piece

Choose the stock size as a relative or fixe size.
---

# Setup: Fixed size box

###- Select the size of:
### X , Y and Z
### - Sizes will depend on the machine
###- Recomended size for G-Aid 112,112,18mm

# Tool Path window settings

note: Once you selec a tool path, this window will appear and will allow you edit the settings.

# Tool.
### Feeds and speeds <a href="https://www.youtube.com/watch?v=gTnkNHB7dss"> Tutorials</a>

####- Spindle speed: _Rotational speed of the spindle_
####- Ramp spindle speed:   _the rotational speed of <br> the spindle while doing ramp movement. <br> (Normal ramp)_
####- cutting feed rate: _speed of the tool when cutting <br> the material._
####- Ramp feed rate: _feed used when doing helical <br> ramping. (helical ramp)_
####- Plunge feed rate: _feed used when doing <br> vertical ramp. (drill ramp)_

# Selecting pocket.

Once you select the pocket continue to the next tab.

---

# Clearance height.
#### Retract height: _is the first height where the tool starts moving._
#### Clearance height: _offset from the wrok piece to avoid colision while moving to the next cut._
#### Top: _top of the model._

---
# Passes.
### Step downs and Step overs <a href="http://xhileno.fabcloud.io/cnc_class/#39"> Tutorials</a>
#### the Goal is to maximize cut and reduce time <br> without breaking the endmill.

####- Optimal Load: _50% of the cutter diameter_
####- Climb Vs Conventional.
####- Step Down.

---

# Linking and Ramps.
### Ramping like a boss
#### depending on the material and chip clearing <br>plunge or Helix might be need it.

---

# Simulation
#### Double check if the toolpath looks fine.
Using simulation you can see the number of step downs and how the endmill will move,
 thus, you can forecast any crashing of issues

###  Out cut / Contour cutting

###  Out cut / Contour cutting

# Remember to Ramp.
### Ramping like a boss
#### Low angle for non agressive cutting <br> dont go depper than to width of the endmill.
