Top Ten Reasons To Buy Cam Express


1. The depth and breadth of the capability of CAM Express

CAM Express offers a broad range of in-depth NC programming capabilities that still exceed the capabilities provided by most of the CAM only software vendors.


A key benefit is the breadth of capabilities being provided all in one CAM system. Machine shops buying other CAM systems may need multiple packages to address all of their needs. With CAM Express they can obtain a range of machine tool programming capabilities such as turning, prismatic milling and drilling , 3 axis milling, 5 axis milling and wire EDM all in one system.

SIEMENS PLM Software is known as a leader in the CAM market place with powerful software for NC programming. CAM Express provides users with access to all of that power and capability in a system that is easy to implement, easy to learn and easy to use.

The depth and power of CAM Express and the range of functions supported enables users and shop owners/ managers to get the most out of their new, more advanced machine tools.

2. CAM Express helps maximize the value of your advanced machine tools.

Many machine shops are responding to competitive pressures by investing in new, high productivity machines. The tooling industry has been transformed by the trend to high speed milling. Likewise, production shops are increasingly implementing multi-function turning centers and mill-turns to reduce setups and cycle times.

These machine tool investments rely on NC programming systems to achieve their best results. If a new turning center causes synch codes to be inserted by hand, the programming process slows down and cycle times may not be sufficiently reduced. If cutting patterns don’t provide constant chip loads, a new high speed mill may struggle with tool breakage.

Constant Chip Loading.#SolidEdge
CAM Express delivers roughing cuts that maximize material removal without exceeding the specified chip load. The most advanced trochoidal cut patterns are applied to any geometry configuration, letting you push your cut parameters to the edge of the envelope. When the ins and outs of tool path patterns introduce corners, alleys, stepover motion, etc., chip loads can spike, damaging tools with shock and heat loads. CAM Express uses a very flexible trochoidal approach that prevents these spikes and keeps your cutting forces steady. This is the way to get maximum productivity out of any machine: push the limits without exceeding them.


Effective Semi-finishing
CAM Express applies a comprehensive set of technology to ensure that finish stock is predictable and consistent. Nothing causes problems with finish cuts like unexpected material, and CAM Express makes sure that your semi-finishing cuts leave the finish stock you expect. Z-level patterns ensure that large steps are not left behind by applying hybrid patterns, automatic cut levels, and steep area containment.

The smoothe#SolidEdgest Z-level finishing
Z-level finishing in CAM Express maintains smooth contact with the part from top to bottom. Step downs ramp gradually down the part, combining the speed and smoothness of a Z-level cut with the constant contact, constant chip load of a spiral pattern.

Streamline operations fit toolpath to the part contours in a smooth, flowing manner that does depend on the underlying surface constructions. This cut method matches contours, whether open or bounded, minimizing lifts, reducing tool wear, and providing excellent surface finish.

#SolidEdgeAutomatic rest milling.

Rest material machining is the application of a series of tools, from larger to smaller, to rough a part. Each tool in the series is asked to cut only what remains from the previous tool. CAM Express automatically tracks the rest material from one tool to the next, helping to program the tool sequence and keeping the dependent operations in synch with their previous operations.

Integrated Milling and Turning CAM Express offers a complete set of turning operations in the same environment as the complete milling operation set. Creating mill-turn operations is as easy as picking the appropriate coordinate system and programming the motion. In process workpiece models and program sequences handle the switch from milling to turning and back again easily and naturally.

#SolidEdgeG-code driven simulation
CAM Express simulates machine tool motion in a robust assembly environment, making it easy to see complex rotations or simultaneous motion graphically before asking the machine to do these advanced motions. Unlike most other systems, however, CAM Express uses the posted G-codes and M-codes to drive the machine simulation functions. This important distinction means that you see ALL of the machine motion, including any tool-change motion or go-home motion or any of the other moves that post processors often inject in to a part program as it prepared for a specific machine tool. When you simulate the internal tool paths from a different system, you might still have a surprise waiting for you at the machine, depending on what tricks the post has up its sleeve. This capability is absolutely essential for programming multi-function turning centers and mill-turns, as well as 5-axis equipment.


  • As shops respond to the pressure cooker of competition, they also need to utilize state of the art CAM technology. It is an integral part of any technology upgrade.
  • CAM Express is capable, proven CAM technology that supports the latest in high efficiency, high capability machines.
