3 types of CNC (3 axis)
-2d 
-2.5d (flat on bottom)
-3d
software: vcarve pro
cut 3d (vetrix *aspire)

VCARVE
-set job size (x,y)
- Z Zero = bottom left (bottom left = off table)
-xy position = bottom left (if looking at diamond, home plate)
rapid gaps
0.75 clearance gap
0.75 plunge
1.5 Z

CREATE POCKET TOOL PATH
cut depth 0.25
select tool (diameter)
cut depth = half the diameter of the bit
stepover = 84%
feeds/speeds
set spindle speed
inch/sec
1 inch feed rate
plunge rate 1/3
feed rate
clear pocket > offset
cut direction
pocket allowance
ramp plunge moves
typically always do ramp
takes a little longer
depends on bit
be really descriptive in naming toolpaths (add piece name, size of bit, type of bit, where z is)
Door 0.25 end mill Z table

CREATE DRILLING TOOLPATH
drop spindle speed to whatever bit is rated for
pick anything thicker than 1/2 inch
use vector selection order
outside right = cut out
inside left = interior work

Cut 3D

1. orientate/size model
-choose top surface
-choose model size
-units > inches
-sides to machine (2 - Top & Bottom)
-next

2. material size/thickness
- material size = bottom (set x,y,z)
-Z Zero = bottom left
-use model silhouette
-set overcut distance 

3. Roughing Toolpath
-select bit (ball nose)
-climb = plastic/metal (nicer finish)
-conventional  = wood
pass depth = 1/8th inch
stepover = 20%
spindle speed = 8500 rpm
inches/sec
feed rate = 1.5
plunge rate = 0.5 (typically 1/3 of feed rate)
rapid clearance = .75
maching allowance (5 or 6 thousands of an inch)
select raster strategy

4. Finishing Toolpath
select bit
set cutting parameters (pass depth, stepover, %, spindle speed, feed rate, plunge rate)
1/8th ball bit
pass depth = .625 (half of diameter of bit)
stepover = 6%
spindle speed = 10000 rpm
feed rate = 2
plunge rate = 0.75 (1/3rd of feed rate)
rapid clearance gap = min 0.5

5. cut out toolpath
