Drill operation on the edge of the part
● Select: Function - Horizontal drill
or
Select
option from the Function Toolbar
Move the cross hair cursor to the required location
First click - Select edge
Move to create Depth
Second click - confirm depth
Move to select diameter
Click to finish
● Adjust the values with the Machining instructions pane at the left
Description - add a description (optional) for the function.
Back - reference the instruction from the back of the part
Co-ordinates - enter the co-ordinates for the drill hole with Xstart and Ystart. Because the operation is on an edge either Xstart or Ystart will be set to 0 (or X or Y).
ZStart value - position in Z direction
Diameter - the diameter of the hole
Depth - depth of the hole
Repeat - Repeats the operations a specified number of times. This is useful for a line of holes. Note that if the repeat is set to a value of 1 the total number of holes produced is 2.
Centre - if checked the XStart, YStart value is the centre point of the drilling and the direction and repeat opitons operate outwards from this.
Direction - use this to specify the direction of the repeated holes. For the horizontal drill the direction is at right angles to the drill. Enter angles by degrees such as 90 or 270 or enter the symbols + or - which mean +90 (or -90) degrees from the angle of the drill. This latter option is useful when the drill is at an angle.
Offset - use this to specify the distance between the repeated holes.
Angle - The drill is positioned anywhere in the part and at any angle or use a single character (L R U D)
0 - up
90 - right
180 - down
270 - left
If a part contains internal horizontal drilling the program prompts with a warning - check that the internal drilling is intentional, for example on the edge of a cut-out.
Transfer to machining centre - the angle option for the horizontal drill is only available for transfer mode 8.
Tool - use this box to enter the tool number and other information. Click on the [+] button to enter options via a dialog (this is only available for some types of machining centre).
Notes
- When the repeat option is used a small X is used to indicate the specified XStart, YStart location which may not be within a drilling instruction.
