Before starting real CNC machining, this is the first thing you want to be sure about. There shouldn’t be any collisions, collision risks (not colliding but very close objects), any NC program errors or CNC axis limit problems.

To lower the first part machining times that normaly takes very long time due to lowered feedrates and pauses

It is a common habit to minimize the feedrates to visually check the NC programs while cutting the first part. Not only feedrates are minimized to check if any collision risks occur, the cutting process is also paused many times, when the operator is not sure what will happen and he/she wants to check what is going on inside the CNC. This habit is very costly. You waste a lot of time of your CNC and therefore lower your profits a lot due to this first cut preparation and checking process. MANUSsim allows you to start your first cutting with real cutting feedrates.

Determine part gouges immediately while simulation is running

Gouges to parts are reported immediately while simulation is running. You can define a tolerance to allow some amount of gouges that is acceptable. Moreover, you can define a negative tolerance if you want to be warned when cutting tool gets closer to part more than you want.

Control your tool cutting conditions

You can give allowable cut depths to your cutting tools, thus MANUSsim warns you when this depth of cut is exceeded. You can also define maximum allowable cutting feedrates for your cutting tools, so you get warnings when your feedrate is above this limit.

Learn real cutting times

MANUSsim calculates real CNC times by taking CNC machine axes accelerations, decelerations and jerks into account. Very close results to real cutting times are obtained. CAM programs do not use machine dynamics while calculating machining times, therefore this is a huge advantage of using MANUSsim. You can use this time information, to prepare quotations and to plan your shop floor activities.

Analyze real cut stock after machining

Although CAM programs can compare cut stock and target model, this comparison is not a real comparison since the cut stock is not cut with real NC code. To be exactly sure about the real cut result, you should compare the target model with cut stock that is machined with real NC code. MANUSsim allows users to do that. The comparison can be easily performed visually, excess materials are blue and getting darker with increasing excess materials. Likewise gouges are in red and becoming darker red when gouge amounts increase. Green are the zones where cut surfaces match target surfaces in the tolerance you defined. You should also have a chance to click on the material and see the amount.

Detect and speed up air cuts, allowing faster CNC machining times and increased profits per part

Side effect of CAM programming is mostly unwanted air cuts, since you have no control on roughing algorithms of the CAM programs and many CAM programs generate unwanted air cuts and uncut touch moves. Air cuts are also generated a lot on multi-axis tool paths. This is because, it takes time to minimize cutting paths individually in each operation and most of the time CAM programmers don’t have this time to make these improvements. Another most common reason is that, when the CAM programmer’s experience is not high, the end results are not well enough. MANUSsim analyze the NC code and detects the air cuts and uncut touch only movements. The feedrates of these movements are automatically increased and you get faster CNC machining times and increased profits per part.
