Tool & Work Offset Setting With G10 Programmable Data Entry

           G10 Programmable offset is used for tool data entry (tool offset) and fixture offset data entry (work offset) in CNC machine. It is very easy to take offset in this method. g10 is used to serve in the datum position program. This code is very useful in a machine when you want to perform an operation on multiple fixtures or do the same process over and over again. Using this code, we can save the time required for offset setting.

1] TOOL OFFSET DATA ENTRY ( Tool offset) - The Tool Holder Presetter Gauge is used to offset the tool. The values ​​of X and Y are found in it, i.e. the diameter and length of the tool are calculated, And you can put that value directly in the offset screen.

G10 L10  P1 R200  ( Programmable offset,  L 10- tool length, P1 – tool offset number, R200 – length value )

G10 L11  P1 R195  ( Programmable offset,  L 11- tool wear length, P1 – tool offset number  , R195 – wear length value )

G10 L12  P1 R50  ( Programmable offset,  L 10- tool radius, P1 – tool offset number, R50 – radius  value )

G10 L13  P1 R47  ( Programmable offset,  L 10- tool radius, P1 – tool offset number, R47 –wear radius value )

2] FIXTURE OFFSET DATA ENTRY (Work  offset) - In this, we have to take offset multiple fixture. The work offset number is usually given as P1 to P6 to understand the work offset coordinate of the fixture to the machine.

Where P1- G54 (work offset coordinate )

           P2- G55

           P3- G56

           P4- G57

           P5- G58

           P6- G59

Block – G10 L2 P1 X-302.5 Y-309.50 Z-522.6 A0.0 ; 

      (Programmable offset, L2- Fixture offset data, P1- workoffset coordinate. you can use as you required to perform, put offset measure value X, Y & Z, A0.0 – In some machine, there is A, B& C axis but here we put zero )
