Course information

Using the Siemens' ShopTurn function, along with ISO codes and Parametric functions, helps fast and efficient programming. The course consists of step-by-step instructions beginning with basic principles and gradually increasing in complexity. Specific descriptions and programming
examples will also be covered in the course as well as showing both turrets working simultaneously. Subjects covered in the course include:

  • Milling and drilling on angles
  • Working both sides
  • Balanced machining times


By the end of the course, you should be able to program components to a reasonable standard, thus achieving the full potential of your CNC Twin Spindle & Twin Turret turning centres.

Applicants should have a basic knowledge of Engineering and an understanding of component drawings would be advisable.

Specific course content includes:

  • Explanation of G code groups, modal, non-modal and active at start
  • G Codes -
  • Group 7 - Tool nose compensation (G40, G41, G42)
  • M functions for the spindles (Group 1)
  • M functions for turret (Group 2)
  • M functions for clamping (Group 3)
  • M functions for the coolant valves (Group 4)
  • M functions for the axes (Group 11) (mirror image etc)
  • M functions for the handling system
  • Explanation of Siemens cycles: Cycle82 - Drilling, Cycle84 - Rigid tapping, Cycle93 -
  • Grooving, Cycle94 - Undercut, Cycle95 - Roughing, Cycle96 -
    Thread undercut, Cycle97 - Thread cutting
  • Explanation and use of Wait marks
  • Drilling and Milling
  • Positioning of the spindles (SPOS, SPOSA etc),Machining planes (G17, G18, G19)
  • G19 Ð C used as a circular axis
  • G17 Ð Axial machining as a linear axis (Transmit, with and without Y axis)
  • G18 Ð Radial machining (with Y axis)
  • Write Example program

This course is run at the Mills Mills CNC Training Academy's facility in Leamington or can be held at a customer's facility. (Charges will be different to above.)

This course is theoretical and classroom-based using Touch Screen Computers with Siemens Sinutrain Control Simulation Software. Time can be spent training on a Siemens-controlled machine depending on availability.

If training is required at a customer's facility, it is important that attendees have a room with a projector & whiteboard available & unrestricted access to a Siemens-controlled Doosan MX or SMX machine if required.
