5.1.3 Example 3 - Double Push
This example demonstrates a double push on the workpiece. The program contains (2)
G105 commands. The first G105 uses the variables values set on the Bar Feeder current
commands page. The second G105 uses J and K values to override the variable values.
This is the preferred programming method when, for example, you need the rigidity of a
short bar for part of your operation, and then to machine the rest of the longer finished part.
The material is 2" (51 mm) diameter solid stock and the finished part is 4" (100 mm) long.
The cutoff tool is 0.125" wide. The spindle/tool clearance is 0.875". The amount of stock to
remove from the face is 0.025".
The program uses these Bar Feeder variable values. These values apply to the first G105
command, given without address codes:
In the second G105 command, the program uses these address codes to override the
values given in the bar feeder variables:
Variable
Number Description Value
#3100 Part Length + Cutoff Allowance + Facing Allowance 1.150
#3101 Initial Push Length 2.025
#3102 Minimum Clamping Length 4.0
Address Code Description Value
J Part Length + Cutoff Allowance + Facing Allowance 3.0
K Minimum Clamping Length 1.0
