Motion profile

This section provides basic information on the motion profile for a load case.

Motion profile 1:

Once a load case has been selected and specified, a motion profile can be created based on sections.

The motion profile illustrates curves along different points. The profiles are specified and evaluated based on certain rules.

Currently, only stop-to-stop movements are considered.

Step 1

Adding a section

Motion profile 2:

To create a profile, you first have to create a section.

  • Open the settings area (1)
    (Left-click on "Add")

Specifying the section

In the settings area you can now specify a section.

Motion profile 3:

  • Enter a name (1) for your section.
  • Select the motion profile (2) for your section.
  • Enter information on the positioning mode, position and duration of the section (3).
  • Confirm your entries with OK.

You have successfully specified your section.

Motion profile 4:

Creating several sections!

You can create any number of sections within a motion profile. The sections may have different distances/durations. To create a new section, repeat the procedure from step 1.

Step 2

Display of motion profiles (trajectory)

Once you have specified your section, the corresponding profile is displayed. The profile shown illustrates a trajectory.

Motion profile 5:

The following process steps are shown:

  • Position
  • Velocity/speed
  • Acceleration
  • Jerk of the load case.

Further basic and section settings

The settings area can be found to the right of the process curves.

Motion profile 6:

Under (1) enter:

  • an initial value for your movement.

Under (2) enter:

  • the positioning mode
  • the position
  • the duration
  • the maximum acceleration
  • the maximum deceleration
  • the jerk of the load case

The setting options are described specific in step 1: "Specifying the section".

Motion profile 7:

Selecting the units!

All units used in the settings area can be changed via pull-down menus (to the right of the input fields). When a unit is changed, the result is shown in the new unit.

Motion profile 8:

Displaying the motion coordinate for the load case!

The motion coordinate and the 0 position are displayed in the motion profile for the load case.

Step 3

If additional or modified process forces occur during the motion (e.g. the cutting force of a milling head), or if the process mass changes (e.g. the transported workpiece is removed from the tool carriage), this change can be reflected in the views. The changes are not tied to the motion sections. The input is time-dependent, which means that additional time sections have to be added.

Selecting views

In addition to the trajectory view, TC3 Motion Designer offers two further views, which are described in more detail below.

Motion profile 9:

You can select the view in the selection bar (1).

 

Viewing the process sequences

Under the Process force and torque tab you can define modified forces or torques.

Motion profile 10:

In addition, you can create several sections via the section settings.

You can switch the view under the view tabs Process mass and Inertia.

The following process steps are shown:

  • Position,
  • Velocity/speed,
  • Acceleration of the defined motion,
  • Process force,
  • Process mass and
  • Inertia


Import CSV:

Motion profile 11:

A variable force can be imported as a CSV file.

  • Assign a section name (1).
  • Open the CSV import menu.
    (Left-click on button 2)
  • Select your CSV file.
  • Confirm with OK.

The settings from your CSV file are shown in the menu (3).

Note:

All data can also be supplied manually, if no CSV file is available.

Motion profile 12:

Configuration example for a CSV import!

Chapter 4.2.1: "Importing a CSV file" illustrates a concrete example of importing a CSV file in your TC3 Motion Designer project. The example is based on version V1.1.0 of the TC3 Motion Designer and Microsoft Visual Studio Shell 2010.
