A BobCAD-CAM post processor is made up of different lines of data. Each line in a post processor is referred to as a “Post Line”. When you have multiple lines of data that go together they are referred to as a “Post Block”. We also have Post Blocks that are a single line and they are referred to as “Post Questions”. Post questions are lines where the user can define and switch settings which control output on a broader scale than a single Post Line would.

Example Post Lines:

n,rapid_move,absolute_coord,work_coord,force_x,xr,force_y,yr,s,spindle_on

n,rapid_move,length_offset,d_offset,zr,coolant_on

Example Post Blocks:

2. Start of file standard

                n,"G00 G17 G40 G49",cancel_drill_cycle,measure_mode,absolute_coord

                " "

                "(FIRST CUT - FIRST TOOL)"

                system_comment

                feature_name_comment

                " "

                "(TOOL #",list_tool_number," ",tool_diameter," ",tool_label,")"

                n,t,"M06"

                force_no_add_spaces

                default_add_spaces

                n,rapid_move,absolute_coord,work_coord,force_x,xr,force_y,yr,s,spindle_on

                n,rapid_move,length_offset,d_offset,zr,coolant_on

                machining_mode

 

In the example Post Block above you can see there are multiple Post Lines that fall

under the Post Block defined by:  “2. Start of file standard”. 

Example Post Questions:

200. Is X modal? y

201. Is Y modal? y

202. Is Z modal? y

203. Are the g codes modal? y
