2 Axis Milling: Air Wall   
  
How to machine open pockets:  
There are situations when one needs to machine steps or "open pockets" on parts. A commonality between these features is that they are not entirely closed. The "missing" walls are commonly referred to as "check" or "air" walls. SURFCAM allows for easy machinery of these part features. A detailed explanation of the entire process and examples will be discussed below.  
  
Steps to machine this feature in SURFCAM:  
Using 2-Axis Contour, select the blue inner profile "A" as shown above; note that by default the Select Chain mode is set to "art"  
Change mode to Material and then select the red profile "B", which defines the shape of the air wall  
Press Done for chain selections and the 2-Axis Contour dialog box will appear  
On the [Tool Info] tab page set the tool, feeds and speeds  
On the [Cut Control] tab it is critical that the "Amount to Remove - On Sides" is set to a value that is greater than the distance from the part to the material boundary  
Press OK, the resulting tool path is shown in the rightmost picture

Adjusting Arc Centers in Edit NC  
  
--------------------------------------------------------------------------------
  
Question:  
My file looks correct in SURFCAM but after posting and Back Plotting in Edit NC, large arcs appear in the Back Plotted code.   
  
Answer:  
The default for the Back Plot arc center option is set to "Auto". This means that the editor tries to determine arc center location methods automatically i.e. “I,J relative to start point”, “I,J absolute”, etc. This is possible for the vast majority of arcs, unfortunately there is no perfect method for doing this. In cases like this where the user suspects a problem with the Backplot, the arc center type should be set manually. To set this option, select ANALYSIS > BACKPLOT > SETUP > BASIC OPTIONS > select “Relative To Start Point” for the “I,J,K Usage On G2/G3:”.  

更改4 Axis後處理 MPost的參數 --- MOD命令的應用:
  
在surfcam四軸後處理 xxxxx.M4裡, 以4軸 A軸為例,
通常位址碼設置如下:
  
% 00
/ 00
O >4
N >4
G >2
g >2 G
X ->4.>3
Y ->4.>3
Z ->4.>3
z ->4.>3 Z
A ->3.>3   
I ->4.>3
J ->4.>3
K ->4.>3
......
  
當你連續切削往往A軸較度值在後面會出現非常大的值(不管是正值 或 負值)
例如: X45.34 Y22.343 Z40. A-99998.945 機床就會報警..
可以更改控制器A軸參數 讓A軸 一直都是 0 -- 359.999 或 0 --- -359.99 然後又是 0 --- 359.999 或 0 --- -359.999,  
也就上面那行程序變成
X45.34 Y22.343 Z40. A-278.945
  
在Surfcam的後處理文件 在A軸位址碼那行要加入MOD命令 如下:
% 00
/ 00
O >4
N >4
G >2
g >2 G
X ->4.>3
Y ->4.>3
Z ->4.>3
z ->4.>3 Z
A ->3.>3 mod 360
I ->4.>3
J ->4.>3
K ->4.>3
