Saw Head Cutting Terminology Turn and Tilt

Optimumcut 1D supports both Turn and Tilt saw head orientations, these orientations are commonly known as saw head operating modes. Most double head mitre (miter) saws or cutting-off machines have fixed Turn mode saw heads set to 90 degrees as standard with manual override adjustment available on certain models.

Optimumcut 1D supports all of the following cutting example saw head orientations and also supports various non standard combinations.

Figure 1. demonstrates a linear material being cut with Turn mode saw heads set to 90 degrees to Left end (Turn Left) and 90 degrees to Right end (Turn Right)

This is a common cutting setting when cutting mullions, transoms and pressure plates on architectural aluminium curtainwall systems, etc.

Note: It is also common for modern CNC saw heads to have pneumatically controlled Tilting heads to perform Tilt mode mitre (miter) cuts of 45, 90 and 135 degrees.

Figure 2. demonstrates a linear material being cut with Turn mode saw heads set to 45 degrees to Left end (Turn Left) and 135 degrees to Right end (Turn Right)

This is a common cutting setting when manufacturing outer frames and vent frames of window systems and door frames and door leaves of door systems, etc.

Note: It is common for modern CNC saw heads to have pneumatically controlled Tilting heads to perform Tilt mode mitre (miter) cuts of 45, 90 and 135 degrees.

Figure 3. demonstrates a linear material being cut with Compound Angles. The Turn mode saw heads are set to 45 degrees to Left end (Turn Left) and 135 degrees to Right end (Turn Right) and Tilt mode saw heads set to 45 degrees to Left (Tilt Left) and 45 degrees to Right (Tilt Right)

This is an uncommon cutting setting and is mostly used when manufacturing special one-off custom products like curtainwall screens which have complex compound angles within their assembled structures.

The Turn Left & Turn Right cutting angles shown in the example below are purely displayed for understanding of concept. Each users angle settings will be unique to their own projects.

Optimumcut 1D supports all of the aforementioned cutting example saw head orientations and also supports various non standard combinations. It is always important to check your saw’s operational cutting parameters before entering data into Optimumcut.

Optimising Multiple Projects

Optimumcut-1D v3 Product Development

It is sometimes desirable to optimise multiple projects at once so they can be processed in the factory at the same time to benefit from economies of scale. Optimumcut-1D v3 Standard & Professional can undertake stock cutting optimisation of all linear materials in multiple projects at once. Individual projects can then be maintained for producing customer facing reports if each project represents different customers, different stages or phases of a large project.

To open multiple projects at the same time, multiple files can be selected in the File / Open dialog. This can be achieved via selecting a region with the mouse or by using the Ctrl or Shift keys to extend the selection.

Multiple Project Open Dialog

There are some rules that users should be aware of when optimising multiple projects in a single report.

  • Each project must have the same length and weight units.
  • The description and notes fields are appended together with a carriage return between each project.
  • Only one project image can be used so the image is taken from the first project that contains an image.
  • All component and material collections are merged together by name. If multiple materials or components share a name but have different specifications then the information from the first one is used.

After opening multiple projects, the main window remains in its previous state and the optimised results window is shown for all selected projects,

Windows 8.1 Preview

Optimumcut-1D v3 Product Development

Microsoft have released a preview of the upcoming update to Windows 8. Currently called the Windows 8.1 Preview, This update attempts to address much of the criticism that has been directed at Windows 8. This post is to highlight the changes that effect Optimumcut-1D.

The 8.1 Preview is installed via the Windows 8 app store. Once installed on a clean environment, you are presented with the usual Start Screen. Returning to the familiar desktop, it now looks like this with the return of the Start Button.

Windows 8.1 Desktop

Desktop icon

Optimumcut-1D is a regular desktop application and so is downloaded and installed from here rather than via the app store. Once installed, our short-cut appears on the desktop as it always has.

The usual right-click menu options are available on this icon. It can be pinned to the Start Screen or the Taskbar.

Pressing the Windows key and returning to the Start Screen highlights the first major change. Our short-cut no longer appears by default on the Start Screen.

Windows 8.1 Start Screen

This is the new behaviour as defined by Microsoft. Application short-cuts do not automatically appear on the start screen. It is now the responsibility of the user to find their new application in the All Apps view. A user can chose to right-click on the icon in All Apps and pin it to their Start Screen.

Windows 8.1 All Apps

Windows 8.1 Screenshot

Once Optimumcut-1D is up and running. the look and feel is exactly the same as it is under Windows 8.

Optimumcut-1D v3 Product Development

Projects Page

To keep our customers up-to-date with the latest Optimumcut-1D software updates and product developments, we have experimented with several techniques for our software to inform the user of these updates. The challenge, is doing this in a way that is not intrusive to what the user is attempting to do with our software, while at the same time not being something that is instantly dismissed and never seen again.

News Page

The recent start screen update allowed us to include the title of the most recent blog post at the bottom of the new start screen. Additionally, a News tab within the File menu also gives users access to the title and the opening sentence of the most recent 10 posts on the Optimumcut blog. This information is available to Optimumcut-1D via the RSS feed provided by our blog which is available to all users via the RSS logo RSS Logo on all our our blog pages.

Excel Import Wizard

Optimumcut-1D v3 Product Development

A common requirement of our customers in Optimumcut-1D Professional and Standard is the ability to import data from Excel. This data will typically come from other software packages like Autodesk RevitAutodesk Inventor, DS SolidWorks, Siemens Solid Edge that are used to design complex curtainwall, window, door systems or other linear products. Typically the data is exported from the other software in a Microsoft Excel format and would be tedious to enter manually in Optimumcut-1D Professional or Standard.

The Excel import feature is available via a right-click menu on the Linear Cuts, Sheets and Accessories sub items of a component.

Import Context Menu

After selecting the “Import” menu item, the import dialog appears.

Excel Import

The import dialog first requires that you select the worksheet that contains the data to be imported. This can be done with the drop-down list at the top of the dialog. After selecting the worksheet, the data from the worksheet is displayed.

It is common for worksheets to contain header information that should not be imported. Optimumcut-1D attempts to automatically determine which row contains the first row of data to be imported. If Optimumcut-1D gets this wrong, the first row of data can be changed by clicking on the row header in the left-hand column. The numbered rows should then match the rows to be imported.

Each column in the worksheet then needs to be associated with a field within Optimumcut-1D. This is accomplished with the drop-down list within each column header. Once all the columns are associated with Optimumcut-1D fields, clicking OK imports the data directly into Optimumcut-1D ready to undertake linear material optimization and produce optimized cutting lists.

Project Cost Savings

Optimumcut-1D v3 Product Development

Although Optimumcut-1D is far more than a simple linear material optimiser, our company strapline is still “Obtain the Maximum from a minimum”. This desire to maximise the yield, minimise waste and reduce project costs is at the heart of all of our software. We have therefore always had a desire to quantify the real-world savings we help our customers achieve.

The latest version of Optimumcut-1D now attempts to solve this problem of quantifying the savings. After optimising a project, the estimated savings are displayed in the top-right corner of the results window along with the percentage saved on the projects’ overall cost.

Cost Savings

It is important to note that this number is only an estimate. We cannot possibly know how efficiently our customers would manually optimise their projects without the help of Optimumcut-1D.

To estimate the savings, Optimumcut-1D performs a second, very fast optimisation. This uses a very simple algorithm that could be calculated manually. The idea is that this is a fair estimate of what a competent employee could achieve without Optimumcut-1D. We can then use this to calculate the difference in project cost between our optimal solution and the manual solution.

This feature clearly provides added benefit to our users but we also wanted to share in that increased knowledge. After calculating the cost savings, Optimumcut-1D therefore sends the saving back to Optimumcut. For any customers concerned about privacy, this data is 100% anonymous and is treated as confidential. We send 3 raw pieces of data:

  1. The 3 digit currency being used on the client PC, i.e. USD, GBP, AUD etc…
  2. The project cost exactly as it appears beside the word “Cost:” in the above screenshot.
  3. The saving exactly as it appears beside the word “Saving:” in the above screenshot.

Optimumcut does not track anything else about the data that is sent or where it is sent from. If you still feel you would not like this data sent to Optimumcut, the entire feature can be disabled via the Cost Savings configuration window.

Cost Savings

This feature is available in Optimumcut-1D v3.5 and later.

New Start-up Screen

Old samples screen

Optimumcut-1D v3 Product Development

The one area we have not been 100% happy with in Optimumcut-1D is the start-up experience of the software.

We implemented a popup samples form to try and show new users the types of projects that can be created even though we do not like popup forms ourselves.

The initial state of the main user interface is also a new empty project. Most of the time Optimumcut is started will be to edit existing projects so we wanted to make this the focus of the start-up experience.

Old recent projects screen

The recent items area of the File menu took its inspiration from Microsoft Word 2010 with a Recent Documents and a Recent Places list.

From our research, no one actually uses the Recent Places list so we decided that could be replaced with something more useful.

These Recent lists are also empty for a new user so the large empty white space is wasted.

While researching different start up screens, we came across Microsoft Access 2010. This offered much of what we were looking for.

Unlike Word, when Access starts-up it automatically shows the File menu with a tab pre-selected. It provides an area to select stuff and an area to create new stuff. This isn’t a perfect match for what we are after but it gave us some inspiration.

From this we decided that we could merge several of our existing concepts together and create a new start-up screen within our File menu.

Our new screen has two areas, an area to open projects and an area to create projects. For new users, it provides a list of samples projects to open, the existing users is provides a list of recent projects. In both scenarios a new project can be created with a project description already entered.

New samples screen New recent projects screen

This new start screen will be available in Optimumcut-1D v3.4.
