Straight line L

Application

With a straight line L you program a straight traverse motion in any direction.

Description of function

The control moves the tool in a straight line from its current position to the defined end point. The starting point is the end point of the preceding NC block.

Depending on the kinematics of your machine, you can program up to six axes in a linear L block.

The TNC7 basic can move up to four axes simultaneously. If an NC block commands movement of more than four axes, the control displays an error message.If the axis position does not change, you can nevertheless program more than four axes.

Input

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

Change the following contents as needed:

  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions (e.g., with M91)
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.

Straight line L with the values of the current position

To enter a straight line L with the values of the current position:

  1. Select the NC block after which you want to insert the straight line L block

  1. Press the actual position capture key
  2. The control inserts a straight line L with the actual positions of all defined axes.
 
Tip
  • You use the actPosAxes machine parameter (no. 105415) to define the axes used by the actual position capture key to create a straight line L.
  • The values are equivalent to the Actual pos. (ACT) mode of the position display.
