The parameter that links these concepts and that is widely used as a standard metric to determine optimal feeds & speeds is called chip load.

On the other side of the graphic, if you reduce the feed rate too much relative to spindle speed, the flutes of your end mill will start rubbing the material instead of cutting nice chips. This action will make your tool overheat, and thus soften. Its sharp edges will become dull and if you keep cutting with dull edges and you will start to see a very deteriorated surface finish on your material.

CPT code 11107 is for each additional or separate incisional biopsy of the skin, used for billing and documentation in healthcare.

CPT code 11005 is for the debridement of the abdominal wall, a procedure to remove dead or infected tissue to promote healing.

Based on this knowledge, we can now use tables that will allow us to calculate our feeds & speeds and achieve an optimal chip load for any given material.

CPT code 11040 is used for the medical procedure of debriding partial-thickness skin, which involves removing dead or damaged tissue.

When billing for CPT code 23420 (Repair of shoulder), it is essential to consider the appropriate use of modifiers to ensure accurate reimbursement and to reflect the specific circumstances of the procedure. Below is a list of potential modifiers that could be used with CPT code 23420, along with the reasons for their use:

CPT code 11471 is for the removal of a sweat gland lesion, a procedure often performed to treat conditions like hidradenitis suppurativa.

CPT code 11420 is for the excision of benign skin lesions on the head, face, neck, or scalp with margins of 0.5 cm or less.

Now let's imagine that your spindle can't run faster than 10 000rpm. We can still increase the feed rate by using a 3-flutes end mill and keep a constant chip load:

Similarly, we suggest you slowly increase the depth of your cuts while doing these tests. Indeed, excessive depth of cut will result in tool deflection (see this article to understand why that can be problematic).

If you're using end mills that you bought at Mekanika, you can access the pre-parametered feeds and speeds for Fusion360 here on the product pages.

CPT code 11626 is for the excision of a malignant skin lesion, including margins, on the face, ears, eyelids, nose, or lips, measuring over 4 cm.

9. Modifier 78 - Unplanned Return to the Operating/Procedure Room by the Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period - Used when a related procedure is performed during the postoperative period of the initial procedure.

An important factor to consider while reading these tables is the tool diameter. A larger end mill will indeed be able to handle a larger chip load.

CPT code 11622 is for the excision of a malignant skin lesion, including margins, on the face, ears, eyelids, nose, or lips, measuring 1.1 to 2 cm.

CPT code 11426 is for the excision of a benign lesion on the head, face, neck, or scalp, with margins greater than 4 cm.

CPT code 11045 is used for billing additional debridement of subcutaneous tissue, typically as an add-on to a primary procedure.

The CPT code 23420 is reimbursed by Medicare, but it is essential to verify the specifics through the Medicare Physician Fee Schedule (MPFS) and your regional Medicare Administrative Contractor (MAC). The MPFS provides detailed information on the reimbursement rates for various CPT codes, including 23420, while the MAC can offer localized guidance and any additional requirements or restrictions that may apply. Always ensure to check the latest updates from both the MPFS and your MAC to confirm the current reimbursement status and any pertinent billing guidelines.

CPT code 11463 is for the removal of a sweat gland lesion. It specifies the procedure for excising these types of skin lesions.

As stated earlier in the article, we recommend that you start by setting the actual feedrate of your machine below the value from the table and gradually increase it. In general, you will find that your optimal feeds & speeds will be determined from experience or trial-and-error. For instance, for most materials, you can typically set the spindle speed between 15000-25000rpm and adjust your feed rate to obtain nice results with your machine.

CPT code 11640 is for the excision of a malignant lesion on the face, ears, eyelids, nose, or lips, measuring less than 0.5 cm.

Always clamp your workpiece in the best possible way. A loose workpiece will vibrate while being cut and cause a bad surface finish. If you are not sure about your clamping, use wood screws to attach your workpiece in many points to the spoiler board. It is not the fanciest clamp in the world, but it is fast and efficient.

Depending on how deep you want your end mill to go inside the material, you will have to adapt your feed rate to spare it.

CPT code 11102 is for a tangential biopsy of a single skin lesion, used by healthcare providers for billing and documentation purposes.

4. Modifier 52 - Reduced Services - Used when the procedure is partially reduced or eliminated at the physician's discretion.

As illustrated above, there are mainly two bad spots that you want to avoid. The first one happens when you reduce your spindle speed too much relative to the feed rate. Doing so, you’re forcing the flutes of your end mill to cut off too much material, which can lead to unwanted vibration or worse, a broken tool.

CPT code 11644 is for the excision of malignant skin lesions on the face, ears, eyelids, nose, or lips, measuring 3.1 to 4 cm, including margins.

CPT code 11421 is for the excision of a benign lesion on the face, neck, or scalp, including margins, measuring 0.6 to 1.0 cm.

Based on this mathematical relation, we observe that if we want to increase the feed rate to cut that plywood faster, we will have to increase the spindle rotational speed as well to keep a constant chip load :

A general rule of thumb is to take passes that are around half the diameter of your mill. But remember, as mentioned above: some more complex or hard materials requires lower depth of cut (typical examples are aluminium and  plexiglas...).

6. Modifier 59 - Distinct Procedural Service - Used to indicate that a procedure or service was distinct or independent from other services performed on the same day.

This is a great starting point if you are a novice. When you are feeling more confident, slowly increase the chip load towards the “Advanced chip load table” values.

An end mill is a cutting tool and with time, it will eventually get dull. As it gets worn out, you will need to take it easier and reduce the feedrate to keep a good surface finish. You can also just replace it or resharpen it.

Understanding how feeds and speeds work is critical if you want to improve your CNC skills. It will help you to optimize your machining speeds, to obtain a better surface finish and most importantly to have a longer tool life. Here's an overvie of what this article goes through:

Let's illustrate this concept and imagine you want to cut plywood with a 6mm 2-flutes end mill. In our case, the recommended chip load for plywood is around 0,1mm/tooth (cf. the Advanced chip load table at the end of this article).

CPT code 11424 is for the excision of a benign lesion on the head, face, neck, or scalp, including margins, measuring 3.1 to 4 cm.
