Departure function DEP LT

Application

The control uses the DEP LT function to depart a contour on a straight line with tangential connection.

Description of function

8H000_42
  • The control departs the contour as follows:
  • On a straight line from the last contour point PE to the end point PN
  • The line lies on the extension of the last contour element.
  • PN is separated from PE by the distance LEN.

Programming DEP LT

  1. To define the departure function:
  2. Program the last contour element with the end point PE and radius compensation
ApprDep

  1. Select APPR DEP
  2. The control opens the Insert NC function window.
ProgramDepLtIcon

  1. Select DEP LT
  2. Use LEN to define the distance to the auxiliary point PH

Example

11 L Y+20 RR F100

; Last contour element PE with radius compensation RR

12 DEP LT LEN12.5 F100

; Distance from PE to PN: LEN 12.5

13 L Z+100 FMAX M2

; Retract in Z, return jump, end program
