Constant Cut Inside Out

A similar strategy to Pocket milling, but much faster and more efficient. It uses high feedrates and deep cuts and can be generated as Climb, Conventional or both way milling.

Constant Cut Ouside In

Mills an open pocket or the top of a part with islands from the outside in. It is very fast an efficient and uses high feedrates and deep cuts. Can be generated as Climb, Conventional or both way milling.


Used for quick part facing to prepare the raw stock for further machining, but can also be used for clearing flat areas in general.


Machine contours with separate lead-in/lead-out, multiple roughing/finishing passes, and multiple depth cuts. Can be applied without creating additional geometry and uses corner smoothing to eliminate sharp motion.


Create Pocket operations for one or more closed contours with and without islands. Can be applied using either a Conventional or Climb milling strategy. The entry point can be selected anywhere on the model and includes options for Plunge, Ramp, or Helix.


Strategies for drilling and hole making are available in CIMCO CNC-Calc. These include Drilling, Counterboring, and Tapping operations.

Thread Milling

Mill internal or external threads. Several holes can be milled in sequence as long as they have the same pitch, etc. For machines that do not support Helix moves, it is possible to linearize movements.

Letter Milling

CIMCO CNC-Calc also supports milling of text. Any true-type font can be used. Simply write the text you need to mill, and CNC-Calc can generate the toolpaths for the text and convert them into CNC code.

Constant Cut

Used to generate a very efficient Roughing operation and can be generated as a One Way or Both Ways operation to improve performance.


Used for removing material fast and easily. The Roughing strategy enables the user to remove material with the use of both Roughing and Finishing passes.


Used for quick part end facing. This strategy is controlled either by entering coordinates or by snapping it to existing geometry.


The Finish strategy is a fast way to take the final finishing cut, making the part complete.


Enables the use of grooving tools to reach those places that can not be reached with normal roughing and finishing tools. Optionally the entries can be performed with pecking motions.

Thread (ID, OD)

Machine any thread OD and ID (optionally using standard tables – metric or inch). Conical threads are also easy to generate.


Used to cut off the part. The Cutoff operation makes it possible to add complex corner geometry to the part before cutoff. The corner geometry can be rounded, chamfered, or chamfered with rounded corners.
