CGTech released a white paper titled “True Constant Chip Thickness Machining: The New Standard of NC Program” discussing a method of creating optimized NC programs to limit chip thinning and excessive forces on CNC machines and cutting tools.

The goal for efficient CNC machining is achieving a constant chip thickness meeting manufacturing standards. Maintaining a tool’s ideal chip thickness through an operation ensures the tool is being used to its full potential. While it’s easy to tell when an NC program pushes a machine or a tool beyond its capabilities through tool breakage, collisions, and undue machine wear, there are no equivalent signs for NC programs that are under performing.

Unoptimized and underperforming NC programs can lead to long cycle times, excess wear on cutting tools, and poor surface finishes on machined parts. While adaptive milling and other optimization techniques have attempted to address the issue of chip thinning, none achieve constant chip thicknesses throughout the whole cut.

The white paper covers:

• How NC program simulation software exposes the problem of variable chip thicknesses
• The issues with existing adaptive milling techniques
• Why spindle speeds and feed rates are critical for NC program optimization
• How to use optimization software to establish a new standard for NC programs

“Anyone doing CNC programming and machining should pay attention to the capability to create ideal NC programs for optimal CNC machining,” Pete Haas, CGTech Product and Cutting Specialist says. “True constant chip thickness will become the new standard in the manufacturing industry.
