BOLT CIRCLE MENU
There are two fields on the Bolt Circle menu that play a significant role in creating the bolt circle pattern.
This menu can be used to create a full bolt circle or partial bolt circle ... and these fields determine that result.
NUMBE OF HOLES IN 360 DEGREES
This field basically determines the angle between the holes. If the input is 8 for instance, the angle between the holes would become 360 / 8 or 45 degrees. Whether creating a full bolt circle array or partial array, this input determines the angle between the holes.
NUMBER OF HOLES ON THE BOLT CIRCLE
This input will determine whether the array created will be a full bolt circle pattern or partial arc. This input is combined with the Angle of the First Hole to determine the starting angle of a partial arc. If this input is 90 degrees, and the number of holes in the bolt circle is input as 3 ... and the number of holes n 360 degrees is input as 8 the following would result :
1)The first hole would be located at 90
2)The angle between the remaining holes would be 360 / 8 or 45 degrees
3)There would be two remaining hole locations ... (90 + 45) 135 degrees ... and (135 + 45 ) or 180 degrees.
CUSTOM DRILL CYCLE MENU
This menu will result in long hand G code ... no canned cycles are used in the output.
The design is to enable the user to create (2) drilling type operations and can be employed when drilling deep holes or drilling in tough materials.
Cycle #1 is designed to be a peck drilling cycle to a specified depth. The depth of cut ... feedrate ... and distance from the top to stop cycle #1 and start cycle #2 are inputs required for this cycle. Users can also set a specific retract amount when peck drilling is employed in this cycle.
Cycle #2 is designed to be a peck drilling cycle with complete retraction to either the R plane or Clearance Plane ... defined by the user input. Depth of cut ... feedrate ... and clearance amount for approach after retract are inputs required for this cycle.
This menu describes the cutting parameters. To input hole locations where this cycle should be executed ... select the HOLE LOCATIONS button at the top of the form.
LOADING LOCATIONS FROM DXF FILES
On some drilling menu forms. there is an option to load hole locations from a DXF file.
When large number of hole locations are required for executing the cycle, KipwareM® allows for the reading of those locations directly from a DXF file. Basically, every element labeled as a POINT in the DXF file will be read in as hole location. So when creating the DXF file, make certain to place a POINT at every hole location prior to saving the DXF file for import.
